专利说明:

The present invention relates to an assembly of at least three modular building elements of a mass exchange apparatus and / or heat and mass exchange method and / or heat using such an assembly. The invention also relates to an apparatus constituted at least partially by an assembly of at least three such modular elements. The present invention relates in particular to a cryogenic distillation apparatus, such as an air separation, constituted at least partially by an assembly of modular elements according to the invention and to a method for modifying such an apparatus. .
On the other hand, the invention is also applicable to other mass and / or heat exchange apparatus, such as a heat exchanger, an adsorption purification apparatus or a distillation column. The apparatus according to the invention can be installed and commissioned quickly. Once installed, it is easy to increase or decrease its capacity and / or energy efficiency. Its maintenance is less complicated and if necessary, it is easy to move. In addition, it is easy to modify the apparatus according to the invention by modifying its capacity and / or the contents of the products it must produce. You can also add or remove a product.
Currently an air separation apparatus can be composed of a plurality of packets, each containing an entire equipment of the apparatus, for example the whole of a column, the whole of a heat exchanger, the whole of an adsorption unit for purification at the top of the air. The dimensions of each packet are determined by the equipment that it must contain and therefore the packages all have different dimensions. Most packages are placed directly on the ground.
It was proposed to have the equipment the air separation apparatus in packets, for example containers, each containing an entire equipment. The assembly of heterogeneous packets each containing equipment requires significant human effort for assembly (welding, wiring, ...), but also for startup (verification, test).
It is known from US-A-4872955 and US-A-6281334 to make a multi-stack distillation column.
In the case of a distillation which does not operate at ambient temperature, for example a cryogenic distillation, once the column has been assembled, it is necessary to construct an enclosure around the column and to fill it with insulating material. '
It is also known from EP-A-913653 to place a first distillation column operating at a pressure in the insulating enclosure and to have another distillation column operating at another pressure in another insulating enclosure above the first column. This construction requires the use of a crane and the assembly of the two enclosures is complicated.

The modular elements are easily joined together, to facilitate the construction of a device and are also easily detached to facilitate the modification or removal of the elements.
Connections of fluid or electricity type or instrumentation between adjacent modular elements, but also the sealing between adjacent modular elements, will be made at the interfaces between two adjacent elements, by docking a modular element with another, not requiring no or little human intervention.
It is obviously conceivable that connections of fluid or electricity or instrumentation may be made by means disposed on the outer walls of the adjacent or non-adjacent modular elements.
The functioning of the modular elements will have been fully validated upstream of the transport of the element (verification, quality control, ...)
In addition, the modular aspect makes it possible to increase or reduce the size of the apparatus for treating a gas, for example an air separation device, and also to easily disassemble it for installation on another site by adding or removing modular elements of modular elements within the same device. The modular aspect also makes it possible to easily multiply the number of devices in parallel (notion of "multi-train").
For maintenance, we can imagine doing a standard exchange with another modular element.
Some modular elements may possibly be changed during the life of the device, for example by a modular element more energy efficient (but certainly more expensive) if the energy cost becomes greater. This configuration method can also be applied to an adjustment of the productions of liquid, of gas under pressure ...
The implementation, in particular of the gaseous fluid connection, will be facilitated by the use of the concept of an apparatus operating at atmospheric pressure or a pressure slightly above atmospheric pressure, for which it will be possible to tolerate certain leak rate.
According to the invention, it is possible to choose a single size of modular element having given dimensions to install part of a device of the apparatus, by using several modular elements each of the same size. Alternatively, two modular element sizes can be chosen, the modular elements of the two sizes each having the same height and the same width but the length of a modular element size being twice that of the other modular element size. In this case, a number of modular elements of a first size and a number of modular elements of a second size will be used.
The dimensions are chosen so that at least one piece of equipment of the apparatus is not only transported on site in the modular element but installed on site to form part of the apparatus that operates, remaining inside the same modular element than that used for transport.
In some cases, a whole equipment of a device, or even several equipment in full, can enter a modular element, for example the equipment can be a reboiler or a condenser, a heat exchanger, for example a heat exchanger more small, such as a subcooler, a pump, a compressor, a turbine, a relief valve or a control room, instrumentation or electrical.
In other cases, particularly when the equipment in working order is high, it is necessary to design the equipment in a series of pieces, each of which is arranged in an individual modular element. The modular elements are then superimposed and the pieces connected in series inside the modular elements to allow operation of the pieces in series, with at least one fluid of a modular element passing through the other modular element. Thus the superimposed pieces make up the entire equipment, such as a column allowing the exchange of heat and / or material, for example a distillation column or a washing column or a heat exchanger or an adsorption tower or absorption.
The height of the piece is chosen so that the piece can enter the modular element. To improve stability, the modular element is arranged with its length parallel to the ground, its width also parallel to the ground and its height being perpendicular thereto.
For the case where a single modular element size is used, the length of the modular element is preferably at least 1.5 times the height of the modular element, or even at least twice the height of the modular element , or at least 4 times the height of the modular element.
For the case where a single modular element size is used, the length of the modular element is preferably at least 1.5 times the width of the modular element, or even at least twice the width of the modular element , or at least 4 times the width of the modular element.
For the case where only one modular element size is used, the width of the modular element may be greater or smaller than the height of the modular element or equal to it.
For the case where a single modular element size is used, the length of the modular element is obviously larger than the height of the modular element and greater than its width.
For the case where two sizes of modular element are used, the length of the shorter modular element is preferably at least 1.25 times the height of the modular element shorter, or even at least 1.5 times the height. shorter modular element, or at least twice the height of the shorter modular element. The length of the longer modular element is preferably at least 2.5 times the height of the modular element longer, or even at least 3 times the height of the modular element longer, or at least 4 times the height of the longer modular element.
For the case where two sizes of modular element are used, the length of the shorter modular element is preferably at least 1.25 times the width of the modular element shorter, or even at least 1.5 times the width. shorter modular element, or at least twice the width of the modular element shorter. The length of the longer modular element is preferably at least 2.5 times the width of the modular element longer, or at least 3 times the width of the modular element longer, or at least 4 times the width of the longer modular element.
For the case where two sizes of modular element are used, the shortest modular element and the longest modular element have the same height and width.
For the case where two sizes of modular element are used, the height of the longer modular element is half the height of the shorter modular element and / or the length of the longer modular element is substantially the same. double the length of the shorter modular element.
The modular elements can be declined according to different configurations.
The modular elements may each contain a portion of equipment having only one main function.
For example, equipment, such as a heat exchanger, may consist of part or all of superimposed modular elements.
An adsorption purification apparatus may consist partly or entirely of superimposed modular elements.
A distillation or washing column may consist partly or entirely of superposed modular elements.
A modular element may not contain instrumentation or power supply and in this case does not necessarily require validation / testing workshop, other than quality control.
On the contrary, a modular element can contain objects having a multitude of functions (rotary machines, such as a compressor, a turbine or a pump, electrical components, instrumentation, processes, fluid distribution devices (pipes , valves ...), becoming a complex module that requires a validation / test / complete control in the workshop The modular element can contain equipment having an "annex" function such as support, control room, electrical room, instrumentation room / analysis, shop / spare part ...
The modular elements can be arranged so that their length is arranged vertically and / or horizontally with respect to the ground, once put in place to constitute the apparatus. The position with the length arranged horizontally relative to the ground when the element is installed at its final position is preferred for reasons of stability and ease of assembly of the elements. In addition, since these elements are generally transported with their length in the horizontal direction, for example by truck or boat, the element remains in the same position for transport and final installation. It is therefore not necessary to provide supports inside the element to prevent its contents from moving when the element is in a vertical position, since the element is always in the horizontal position, whether it is for transport, on-site installation or final disposal on site.
The structure of at least the modular elements in contact with sections of the apparatus operating at a subambient or even cryogenic temperature will be in a material that is mechanically resistant to low temperature or in a more conventional material protected by adequate thermal insulation.
The walls of the modular element will be flat, or "curved" outwards or inwards if it is easier to contain the pressure. The solution "convex" inward facilitates the transport (the wall does not exceed the "carrier" structure). The insulation may be integrated with the walls and structures exposed to the ambient environment, for example using vacuum panels. The use of more traditional insulation (particulate, for example perlite, glass wool filling or rock) may also be provided according to the accessibility required for the maintenance of the equipment concerned.
The wall of the inner zone with its possible insulation delimits a chamber and can directly "contain" the body having a process function (for example, exchange waves for heat exchange, structured packing for distillation, adsorbent for adsorption, compression, relaxation). Connectors for transferring at least one fluid between the modular elements can be made by welding or preferably by a mechanical system with a seal compatible with cryogenic temperatures and with the nature of the product to facilitate scalability and ease of disassembly , both at the level of the fluid distribution ("pipes") or at a connection between two parts of the same process function. The mechanical strength of the assembly of the modular elements may, for example, be provided by a twist lock type system (in English "twist-lock") preferably housing in the standardized corners of the modular element) regardless of the connection " fluid ", the connection" fluid "just ensuring a seal, which may be imperfect.
The other connectors (electricity, instrumentation) are more classic type "plug and play"
There may also be piping external to the modular elements to connect two parts of the device, especially in the case of fluids under pressure above a given threshold.
The modular elements have guides and quick locking systems in the corners, allowing precision in plug and play connections.
The civil engineering can remain simple, using a single flat slab or only piles located under the structure, possibly only corners, of each modular element resting on the ground. The modular element resting on the ground can be possibly reinforced, for example, by adding point of contact with the ground.
The modular elements preferably have a structure such that the mechanical forces between elements or the ground are preferentially taken up in the corners. The insulation of a modular element is integrated in the walls of the element and possibly in the structure of the element. This avoids the formation of thermal bridges.
A modular element has at least one dimension, or even two or three, greater and / or at least one dimension, or even two or three, lower and / or at least one dimension, or even two or three, equal to those of a standardized container maritime. Typically the modular element has at least one dimension corresponding to the size of a standard shipping container of 20 feet or 40 feet, or about 2.5 x 2.5 x 6 m or 2.5 x 2.5 x 12 m.
An element can have at these eight angles a standardized wedge of maritime container, for example according to ISO 668. The invention will be described in more detail with reference to Figures 1,3 and 4 which represent modular elements according to the invention. invention and Figure 2 which shows two superposed modular elements to form an assembly according to the invention, in Figures 5 to 8 which represent assemblies of modular elements according to the invention, in Figure 9 which shows a section of modular elements assembled according to the invention, in Figure 10 which shows a section of a modular element according to the invention, Figures 11 to 13 which show assemblies of modular elements according to the invention and Figures 14 to 19 which represent a life cycle of an assembly of modular elements according to the invention.
Figure 1a is a top view of a modular element. A view from below would be substantially identical. The modular element 10 is an element allowing an exchange of material and / or heat. It is composed of a box 2 of parallelepiped shape, formed of beams for example metal. The element has eight ISO 101 "container" wedges attached to the casing 2 and has a width oriented horizontally to the ground, a length oriented horizontally to the ground and a height oriented vertically to the ground when it is installed to be part of a device.
ISO containers are subject to specific building standards and performance tests. It's the same for ISO corners.
ISO corners are certified by an internationally recognized organization to allow their "multimodal" use in maritime, road, rail or even air transport.
ISO wedges made of steel, aluminum or stainless steel are commercially available for their specified purpose. The element comprises a box having a horizontal opposite upper and lower face, two opposite vertical end faces and two opposite vertical side faces, the upper and lower faces of the box being defined by the length and the width of the box, the two front faces of the box by the length and height of the modular element and the two side faces of the box by the width and height of the box. The side and front walls are for example sheet metal. The faces formed by the width and the length of the element are open to allow the passage of fluids. Alternatively, the opening may be smaller than the surface of the lower and / or upper face, covering at least a portion of the insulation 3 and possibly part of the zone 4.
It is obvious that the height and the width of the element are not necessarily identical, so that the side walls can all be rectangular without being square. The walls may also be smaller than the dimensions of the element box. The walls are preferably fixed inside the box 2, but can be fixed outside thereof. An insulator 3 dresses the box 2 on the inner side, at least on the vertical sides of the parallelepiped. The upper and / or lower face may also comprise a wall, and be isolated. The insulator 3 can be plated on a sheet which rests on the casing 2 to ensure a "fluid" seal between the interior and the ambient. The insulator 3 can also directly provide this sealing function, as well as the structuring wall function. Otherwise, a sealed wall, for example a metal sheet, may be applied on the inside of the insulator 3. The box 2 and the insulator 3 delimit an internal area. The casing 2, the wall and / or the insulation 3 may be sized to contain the possible overpressure inside the inner zone.
The inner zone surrounds an area 4. This zone 4 contains a body which makes it possible to carry out mass and / or heat transfer, for example structured packing to make distillation, a plate and fin exchanger matrix for making heat exchange, adsorbent in the form of beads or structured to adsorb. This zone may also contain an area of the support, for example in the lower part, fluid distribution zones, for example in the lower part and / or in the upper part. It can also be partitioned into several parts, for example vertically, with walls that can be sealed, and / or structuring (for example, withstanding a differential pressure) and / or thermal insulators. Preferably the body fills the entire section of zone 4.
At least one fluid flows upwards or downwards through zone 4. In some cases, for example that of distillation, a fluid, for example a gas, flows upwardly and another, for example a liquid, so that descending through zone 4.
The inner zone may be entirely made up of zone 4. However, as illustrated, it may also also contain at least one other zone, for example here a fluid circulation zone 5, delimited by a leaktight and possibly insulating wall 6, in a kind of sheath. The part in contact with the insulator 3 may be delimited by a sealed wall, for example metal, if the insulation does not provide this function. In the case of the figure, two fluid circulation zones 5 are delimited by a vertical leaktight wall 6. This makes it possible to replace gas or liquid lines of a conventional apparatus by circulating at least one fluid to be sent to a modular element higher or lower and not to be treated by mass exchange and / or heat in the element through which they circulate.
It is also conceivable that the inner zone comprises several zones 4. For example, one could have a first zone 4 and a second zone separated from each other, each containing structured packing to make distillation or a matrix of plate and fin exchanger for heat exchange or adsorbent in the form of beads or structured to adsorb.
Similarly, the at least two zones could each have a different function or different dimensions, one containing structured packings and the other a plate and finned exchanger matrix.
The fluid sent into the zone 5 can be directly in contact with the walls of the zone, which separate the zone of the insulation. Otherwise the fluid can be contained in a pipe that passes through the area.
Figure 1b shows a section on line X-X of Figura 1a. It shows the four beams of the box 2 and two of the side walls attached to the inside of the beams and coated with insulation 3. A mass exchange body and / or heat of the first zone 4 is held in place by the insulator 3 and is supported by a distributor 4 'for dispensing a gas passing from the outside of the element to the body or the body to the outside of the element. This dispenser can also be used to hold the body in place. This distributor can be reduced to a set of support beams. The body may be a mass exchange body only, a heat exchange body only, (for example a plate and fin heat exchanger) or a mass and heat exchange body.
Figure 1c shows a variant of the element with a section on line Y-Y of Figure 1a. It shows the four beams of the caisson 2 and two of the side walls attached to the inside of the beams and coated with insulation 3.
A barrier 6 divides the chamber 5 in two to form two gas paths, one of the two paths being again divided in two by the barrier 6 ', the barriers 6, 6' forming a T. The gas rises or falls in the path coming from outside the element.
Figure 1d shows a variant of the element of Figure 1c with a section on line Z-Z of Figure 1a. Here instead of occupying the entire height of the element as in the most frequent case of Figure 1a, 1b, 1c, the body is divided into two parts 3, 4, each having a distributor and / or a set of beams support, down, the two parts being separated vertically from one another by a space.
The gas rising in the path 5 next to the body 4 enters the body 3 through the distributor 3 '.
Figure 2 shows a view on the side of an assembly of two modular elements according to Figure 1a. For each modular element, we see the four beams of the box and one of the side walls coated with insulation. The stack of two parallelepiped-shaped modular elements 10 and 20 forms an assembly of two modular elements interconnected by mechanical connection pieces 141 at the ISO corners 101. The opening between the two parallelepiped-shaped modular elements, generated by the connecting piece 141 and / or by the spacing of the beams between the frames of the two modular elements, is filled by an element 131 which ensures both the sealing vis-à-vis the outside and the continuity of the insulation between the two modular elements of parallelepipedal shape 10 and 20. The element 131 may be composed of several sub-elements, for example one providing the isolation function and another the sealing function. The connecting piece 141 can be made so that the upper and lower ISO corners are in contact, for example, by an internal mechanical connection to the ISO corners or outside by using the lateral holes of the ISO corners. The opening between the two parallelepiped-shaped modular elements is then reduced to its minimum, approximately 2 cm, corresponding to the positioning gap of the horizontal metal beams and the ISO corner 101, in general, around 1 cm. Other ways of assembling the modular elements and / or sealing between the modular elements can be envisaged, for example welding and / or a seal, for example made of PTFE or its derivatives and / or bonding by adhesive in addition to or in replacement of a mechanical connection. The beams can be interconnected by a mechanical system, typically bolts, in the manner of a pipe flange, to reinforce the seal if necessary.
Obviously more than two elements can be assembled in this way.
As the two elements have the same length and the same width, it is sufficient to fix one element on the other by the corners 101 which are contiguous, in order to attach the elements together. The space between the elements is filled at least with the seal 131 so that the fluids in the zones 4 can not leave all the elements but pass entirely from one element to another.
FIG. 3 represents a top view of a modular element according to FIG. 1a carrying the sealing element 131.
This figure shows the location of the sealing element, for example a seal 131, at the interface between two parallelepiped-shaped modular elements 10, 20. The element 131 is based on the thickness of the insulation, and also preferentially on the box 2, with the exception of the ISO 101. Other elements 132, 133 and 134, possibly of the same nature as the element 131, will ensure the continuity of fluids between the two modular elements of parallelepipedal shape 10, 20, in terms of sealing and possibly insulation: the element 132 in the case where the zone 4 has been partitioned into several parts, for example vertically, with walls that can be sealed, the element 133 in the case where it is desired to channel a fluid leaving the zone 4, typically at the outlet of a heat transfer, the element 134 for the fluid circulation zones 5.
These elements 131, 132, 133 and 134 can be put in place during the assembly of the two parallelepiped-shaped modular elements 10, 20. These elements 131, 132, 133 and 134 may possibly constitute a single piece.
FIG. 4 is a top view of a variant of FIG. 1a in which zone 4 does not contain a body which is only part of a mass / heat transfer element but contains a complete equipment 7, for example heat transfer, which comprises for example an inlet 8 and an outlet 9, which pass through the insulator 3, the possible structuring wall and / or sealing, and possibly the structure 2.
In this case, an element of a separation apparatus is sufficiently small or complex to be divided into several sections, each of which would be in a respective modular element. This is typically the case of heat exchangers used as reboilers or as condensers.
At least one fluid flows upwards or downwards through the interface between two parallelepiped-shaped modular elements, at the level of the zone 4, the two parallelepiped-shaped modular elements being of the type shown in FIG. 4, or FIG. 1a and Figure 4.
In FIG. 5, a gas separation apparatus 1, for example air, is at least partially made up of different modular elements 11, 12, 21, 22, 23, 24, 31, 32, 33, 41, 42, 43, 44, 45, 46, 47 and 48 as described for at least one of the preceding figures. They are of parallelepipedal shape and comprise at least 8 corners 101, for example ISO of container type, fixed on a structure, assembled for example as described above.
For example, the modular elements 11 and 12 may be dimensions of a normalized container 40 feet long and the other modular elements 21, 22, 23, 24, 31, 32, 33, 41, 42, 43, 44, 45, 46, 47 and 48 of dimension of a standardized container of length of 20 feet.
The circulation of the fluids respectively in a first stack composed of the modular elements 21, 22, 23 and 24, a second stack composed of the modular elements 31, 32 and 33, a third stack composed of the modular elements 41, 42, 43, 44, 45 , 46, 47 and 48 is substantially vertically within each modular element and each stack, and substantially vertically at the interface 11, 12 between two modular elements of the stack. Each stack is arranged so that the longest edge of the modular elements is parallel to the ground.
In the case of an air separation, the first stack 21, 22, 23 and 24 can essentially perform the function of pre-cooling and purification at the head, the second stack 31, 32 and 33 the exchange function and the third battery 41, 42, 43, 44, 45, 46, 47 and 48 the cryogenic distillation function between nitrogen and oxygen.
The third stack could be a single column operating at low pressure or a plurality of columns at different pressures, each consisting of a few elements of the stack.
The modular elements 11 and 12 make it possible in particular to circulate the fluids horizontally through rectangular ducts and / or round pipes so as to transfer the fluids respectively between the first stack 21, 22, 23 and 24 and the second stack 31, 32 and 33, the second stack 31, 32 and 33 and the third stack 41, 42, 43, 44, 45, 46, 47 and 48. The modular elements 11 and 12 can also provide process and / or control functions and / or or utilities-. For example they may contain control means and / or control and / or analysis and / or instrumentation and / or supply of utilities, such as electricity or air instrument. The modular element 11 is placed astride the modular elements 24 and 33, above the first and second cells, and the modular element 12 placed astride the modular elements 31 and 41 under the second and third cells. The modular elements 11 and 12 preferably comprise intermediate ISO corners 102 to facilitate assembly respectively with the modular elements 24 and 33, with the modular elements 31 and 41. The modular element 11, 12 can be isolated in different ways. It can be isolated by depositing an insulator on the outside of the box. It can be insulated by coating the inside of the front and side insulation faces and in addition the upper or lower face if it is exposed. Another possibility is to isolate the at least one pipe or the at least one sheath inside the element 11,12.
Since the elements 11, 12 comprise only two openings, these openings being in the lower face and the upper face respectively, the elements 11, 12 serve essentially to transfer a fluid from one stack to the adjacent stack, and possibly to change the direction of fluid flow through the piles. Thus a fluid passing through the first stack from bottom to top can pass through the second stack from top to bottom. Note, however, that a fluid can cross the two batteries in the same direction. For example, a gas passes through the first stack and is sent to the second stack through the element 11. Then it goes down to the element 31 via the zone 5 of the elements 33, 32, 31 before being sent to the room of the element 31.
This would make it possible, for example to form a distillation column, by using two stacks of elements, for example the first two stacks of FIG. 5. The gas rising in the distillation bodies of the elements 21 to 24 would be sent by the zones 5. elements 33 to 31 to the distillation bodies of the elements 31 to 33 it will go from the bottom.
The column thus formed would have a particularly small height.
FIG. 6 differs from FIG. 5 by the addition of a fourth additional stack composed of modular elements 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61 and 62, which in the case separation of air can essentially ensure the function of cryogenic distillation between argon and oxygen. The modular element 43 of Figure 5 has been replaced by the modular element 13 which allows in particular to circulate the fluids horizontally through rectangular ducts and / or round pipes so as to transfer the fluids respectively between the third stack 41 , 42, 44, 45, 46, 47 and 48 and fourth additional stack 51.52, 53, 54, 55, 56, 57, 58, 59, 60, 61 and 62. The modular element 13 is placed within the third stack (between the modular element 42 and 44) and within the fourth additional stack (between the modular element 53 and 54). The modular element 13 makes it possible, if necessary, to circulate fluids vertically between the lower part of the third stack 41 and 42, and the upper part of the third stack 44, 45, 4 ©, 47 and 48. The modular element 13 allows in this case to distribute the gas from a single stack on two batteries. Here for example a gas of an intermediate point of the third stack, constituting a simple low pressure distillation column, is enriched in argon. This gas continues in part its way up the single column, that is to say the elements 45 to 48 but is also sent to the top of the fourth additional battery 54, 55, 56, 57, 58, 59 , 60, 61 and 62.
By cons, no fluid passes from the element 53 to the element 54 through the element 13. In other configurations, at least one fluid can pass from the element 53 to the element 54 through the element 13 and vice versa.
Elements 51 to 53 may have several variants. They can be simple supports in which case they do not even contain insulation, being simple empty boxes. They may contain other elements useful for the process, for example pumps. The elements 51 to 53 may be modular elements according to the invention as illustrated in Figures 1 to 4 with a chamber containing a distillation packing body. They may for example form a denitrogenation column, with the pipes containing the argon produced by the element 62 sent through the zones 5 of the elements 62 to 54, the element 13 and the zones 5 of the elements 51 being sent to the element 51 to be distilled therein and to provide a product rich in argon from the element 53.
Figure 7a is a front view and Figure 7b is a rear view of the same assembly.
In contrast to FIG. 5, the stacks of parallelepiped-shaped modular elements that have at least 8 container-type ISO 101 corners attached to a structure are contiguous along the length of the modular elements, instead of the width.
To fix ideas, the modular elements 21, 22, 23, 24, 31, 32, 33, 41, 42, 43, 44, 45, 46, 47 and 48 are of dimension of a container 20 feet. If the invention as described in Figure 5 (ie, having a container that "overlaps" two containers of two adjacent stacks), the modular link elements 11 and 12 of the figure would have a width that is double that of a container format, which does not allow its transport and handling by conventional means.
In Figures 7a and 7b, the horizontal connection between the first stack and the second stack, respectively the second stack and the third stack, is made using two modular elements 11a and 11b, respectively 12a and 12b, the width and the height being that of a conventional ISO container, and the length adjusted to two standard ISO container widths so as to properly associate with both stacks. This configuration allows its transport and handling by conventional means.
The connection between the first stack and the second stack could be achieved through a single modular element 11a, and that between the second stack and the third stack to a single modular element 12a, the modular element 12b can then be reduced to its sole structure function.
In contrast to Figures 7a and 7b, for Figure 8, the width of the modular elements 11a, 11b and 11c, respectively 12a, 12b and 12c has been reduced so as to place three modular elements between the two stacks, without creating "empty" between the modular elements, while maintaining a format that allows its transport and handling by conventional means of ISO container.
Figure 9 illustrates the connection between two batteries, for example the assembly 12 of Figure 5. This is a side view. The modular elements 31 and 41 are arranged on the modular connecting element 12 which is arranged on a non-illustrated support. At each ISO corner there is a mechanical connection piece and the element 82 provides both external sealing and continuity of the insulation between the modular element 12 and the modular element 31, respectively 41, as described above. The element 71 symbolizes a fluid sheath (or a pipe) which makes it possible to pass from / to the modular element 31 towards / of the modular element 41 while passing substantially horizontally through the modular element 12, having a vertical transfer from / to the modular element 31, respectively the modular element 41 to / from the modular connecting element 12, the joining plane then being horizontal. The modular element 12 preferably has intermediate ISO corners 102 to facilitate assembly with the modular elements 31 and 41.
Figure 10 illustrates (seen from above) an alternative to Figure 9 of a modular connecting element 12. The element 71 is a fluid sheath for moving from one stack to another. Element 72 is a fluid pipe for passing from one stack to another. The spaces 73 and 74 delimited by internal walls and the wall of the insulator 83 make it possible to pass fluids between the two stacks. The modular connecting element 12 may also contain process equipment: for example, a piece of process equipment 91, such as a material and / or heat exchange body, may be delimited by the insulation 83 and an inner wall, or another piece of process equipment 92 with its own container, for example a distillation column. The modular link element 12 can also also contain control functions, instrumentation and / or utilities. The modular element 12 preferably comprises intermediate ISO corners 102.
Figure 11 differs from Figure 5 by doubling the second stack into two parallel sub-stacks 31a and 32a, 31b and 32b, respectively. The modular elements 12b and 11c make it possible to transfer fluids to / from the two sub-stacks, from the modular elements 12a and 11b. Modular element 12c can be reduced to its sole function of structure. The modular element 11a makes it possible to transfer fluids to / from the first stack 21, 22 and 23.
The modular elements 11a, 11b, 11c, 12a, 12b and 12c may have the same height as the other modular elements, or preferably a reduced height for example of half, as shown in Figure 11.
Figure 12 differs from Figure 11 by doubling the first stack into 2 parallel sub-stacks 22a and 23a, respectively 22b and 23b. The modular elements 11a and 21 make it possible to transfer fluids to / from the two sub-stacks.
FIG. 13 differs from FIG. 5 in that the elements 21, 22, 23 and 24 are larger in size than the modular elements 31-33 and 41-48, for example containers 40 'and that the connecting element 11a intermediate size between 20 'and 40' so as to overlap the two piles 21-24 and 31-33. The battery 21-24 has a different orientation from the other batteries, especially the adjacent one 31-33, preferably perpendicular.
Figures 14 to 19 describe an example of a life cycle of an apparatus for separating and / or liquefying gas, for example air. The apparatus is constituted at least in part by different parallelepiped-shaped modular elements according to one of FIGS. 1 to 4. which comprises at least 8 ISO 101 container-type wedges fixed on a structure, assembled for example as described above. .
Figure 14 illustrates the construction of the apparatus in its initial configuration. The various modular elements A, B, C, D, E, F, G, H, I, J, K and L are of two different sizes. The modular elements all have the same height and width. On the other hand, the modular elements C and E are substantially twice as long as the others. Optionally, A, L and K may also be substantially twice as long as the others
The modular elements are superimposed on three vertical piles. Each stack consists only of elements of one of two sizes. The modular elements come from a manufacturing center CF and / or a logistics platform PL where several elements of each of the two sizes are stored. There are several copies of each element and each type of body, to replace any faulty element. Thus a single manufacturing center and / logistic platform can serve several devices in very distant places, storing replacement elements. A quality control process ensures that each modular element is functional.
The various modular elements are assembled on site by stacking them to constitute at least a part of the apparatus.
The first stack comprises an element A, surmounted by three elements B and a part of the element C.
In the case of a cryogenic air gas separation apparatus, the modular element A may contain an air blower and a pre-cooling, the modular elements B of the adsorbent for purifying the air from the blower in A and the modular element C fluid transfer sheaths from the first stack to the second stack and / or the second stack to the first stack.
The modular elements are designed so that the air rises from the lowest modular element B to the middle modular element B and then to the upper modular element B, purifying with water and carbon dioxide. carbon and some of the secondary impurities in the air. Then the purified air of the modular element B from the top is transferred to the sheaths of the modular element C to pass into the second stack. The regeneration nitrogen is transferred by the modular element C from the second cell to the modular elements B.
The second stack is placed next to the first stack so that the side walls of the modular elements of the two stacks touch each other, possibly with a small day in between.
The second stack comprises a portion of the modular element C containing the sheaths described above, the three modular elements D each containing a heat exchange section, and a portion of the modular element E containing sheaths for transferring to the at least one fluid from the second stack to the third stack and / or at least one fluid from the third stack to the second stack. The purified air passes through the modular elements D to be cooled to a cryogenic temperature and distillation fluids pass from the modular element E to the modular elements D to be heated.
The third battery is placed next to the second battery so that the side walls of the modular elements of the two batteries are touching, possibly with a small day in between.
The third stack, higher than the other two, comprises at the bottom part of the modular element E with its fluid transfer sheaths. Above E is the modular element F which is a vaporizer. Above F are superposed the three modular elements G each containing a distillation section. The modular element H contains a condenser and optionally a distillation section and is above the lowest of the modular elements G. Then come the three modular elements I each containing a distillation section. Above the highest section of the modular element I is a condenser. Alongside the other sections are the modular element K which contains a heat pump for distillation and the modular element L which contains a heat pump for the refrigeration balance of the apparatus.
It is obvious that the scheme could be simplified by eliminating the modular elements L, K and / or the condenser J. The number of modular elements B, D, G and I can be modified to produce the required products or by modifying the heights modular elements.
The installation of the device is limited to have the modular elements on top of each other and ensure that they are well attached and sealed to each other and that the battery is securely attached to the ground. This can be achieved by unskilled labor.
Figure 15 illustrates a first evolution of the apparatus of Figure 14 during its life cycle. A new modular element I containing a distillation column section comes from a manufacturing center CF and / or a logistics platform PL. It is interposed between the upper modular element I and the modular element J, for example to increase the purity of a product. For this it is sufficient to remove the condenser J, to have the new modular element I in place of the condenser and replace the condenser J above the new modular element I. In this way, four modular elements I are superimposed instead three.
In the case of a cryogenic air gas separation apparatus, the modular element I may contain a distillation section for the purpose of producing pure nitrogen ("minaret").
To reduce the energy consumption of a device we can add: o A modular evaporator / condenser element at the top and / or in the column or at an intermediate column level to reduce the nip of the vaporizer and / or condenser or for add a vaporizer function or additional intermediate condenser o A modular element containing a distillation section (s) o A modular element of exchange line to heat exchanger elements to reduce its pinching and thus reduce the consumption of the heat pump assessment o A modular element containing a "low energy" heat pump or a modular element containing a heat pump connected in parallel with an existing heat pump or connected in part to an additional vaporizer or condenser
To reduce the energy consumption of a device can be changed modular elements by modular elements more efficient.
To modify the apparatus to produce impure oxygen, a modular distillation element can be omitted. The added or removed modular element may also contain a liquid product pump, a liquefier or a product compressor.
Figure 16 illustrates a maintenance of the apparatus of Figure 15 during its life cycle. . A functional modular element L comes from a manufacturing center CF and / or a logistics platform PL and replaces the defective modular element L. The defective modular element L is returned to the manufacturing center CF and / or to a logistics platform PL where it can be repaired and made available, or dismantled, possibly recycling part of its components.
It may also be decided to replace the modular element L which would still be functional by a new modular element L more energy efficient for example, or even more efficient in capacity (debottlenecking).
This maintenance operation can obviously be performed for any element A, B, C, D, E, F, G, H, J or K of the device.
Figure 17 illustrates a second evolution of the device of Figure 15 during its life cycle. New modular elements J, F and K come from a manufacturing center CF and / or PL logistics platform and are interposed at different locations of the device, for example to increase the energy efficiency of the device.
In the case of a cryogenic air gas separation apparatus, the energy consumption can for example be reduced on the one hand, by doubling the vaporizer by adding a modular element F and / or by doubling the condenser by adding a modular element J, to reduce the thermal nip of these exchangers, on the other hand, by doubling the heat pump for distillation by adding a modular element K, to operate the pump to heat with better performance.
Here again the installation of the new elements is easy and it is enough to move the other elements to dispose the new element just above or just below another modular element having the same function (thus identified by the same letter of the alphabet) or not having the same function.
Figure 18 illustrates a third evolution of the apparatus of Figure 17 during its life cycle. New modular elements Μ, N, O and P come from a manufacturing center CF and / or from a logistics platform PL and are interposed at different locations of the apparatus, for example to produce another product. Here the new modular elements are arranged to form a fourth stack.
In the case of a device for separating cryogenically air gas, it is possible, for example, to produce argon: The modular element M may contain transfer sheaths and is larger in size. The fourth battery comprises at the bottom the modular element P which contains a pump for raising liquid, then the three superposed modular elements O each containing a distillation section. Part of the modular element M, which is inserted in the third stack is above the upper modular element O. Then above the part of the modular element M present in the fourth stack, there is eight modular elements N superimposed each containing a distillation section. The head of the fourth stack is surmounted by a condenser H, moved from the third existing stack of Figure 17.
Figure 19 shows the end of the cycle of the device. It can either be moved to another place, or simply disassembled: in the latter case, at least one of the modular elements A, B, C, D, E, F, G, H, I, J, K, L , Μ, N, O, P is returned to the manufacturing center CF and / or to a logistics platform PL where they can be either made available, or modernized or dismantled, possibly recycling part of their components. In particular, an item that is no longer required on a first device can be returned to the manufacturing center or the logistics platform, possibly stored on site and sent to a second device when an item need arises. This mode of operation has advantages of speed of intervention, economy of scale and ecological management.
