[0001] This application claims priority for US Patent Application Serial No. 12 / 877,177, which was filed on September 8, 2010, which claims priority for US Provisional Patent Application Serial No. 61 / 242,645 , which was filed on September 15, 2009. These priority requests are incorporated as a reference in their entirety to this request, to the extent that they are not inconsistent with this request.
[0002] In compression systems a multiphase fluid is usually separated in phases, before compression, so that the appropriate machinery and processes can be used in the respective phases. For example, a compressor may be suitable for a gaseous portion of multiphase fluid, but unsuitable for a liquid portion. To separate gaseous materials from liquids, rotary separators can be used.
[0003] In some compression systems, however, multiphase fluid can reach an inlet of the compression system containing more particulate matter, liquid phase or other types of contaminants, than what the rotary separator is designed to handle. In addition, it may be desirable to have multiple passes in the separation of the multiphase fluid. In such cases, the compression systems may employ an arrangement of spiral tubes to perform the first separation. The arrangement of spiral tubes, however, introduces a pressure drop in the compression system and generally requires a large number of spiral tubes to be effective, increasing the size, complexity and, therefore, the cost and requirements of maintenance of the compression system. Thus, what is needed is a compact specific weight-based separator that does not suffer from head losses or other drawbacks of spiral tube arrangements.
[0004] The modalities of the exhibition can provide an apparatus for the separation of a fluid. The apparatus may include an inlet duct having an inlet inlet and an inlet outflow, the inlet duct defining an inlet width that decreases between the inlet inlet and inlet outflow, and an inlet radius that decreases between inlet flow intake and inlet flow discharge. The apparatus may also include a separation curve fluidly connected to the inlet outlet of the inlet duct and including an outer surface that defines an opening. The apparatus may further include a liquid outlet fluidly connected to the opening of the separation curve to allow a higher specific weight component of the fluid to exit the separation curve, and an outlet duct having an outlet flow inlet connected to the curve of separation, to allow a lower specific weight component of the fluid to come out of the separation curve.
[0005] The modalities of the exhibition also provide a static separating apparatus for the separation of a higher specific weight component of a fluid from a lower specific weight component of the fluid. The static separator apparatus also includes a liquid outlet fluidly coupled to the openings, the liquid outlet configured to receive at least part of the higher specific weight component and an amount expelled from the lower specific weight component from the separation curve through of the openings. The static separator apparatus also includes a gas return channel extending from the liquid outlet and intercepting the separation curve, the gas return channel configured to derive at least part of the amount expelled from the lowest specific weight component of the liquid output back to the separation curve.
[0006] The modalities of the exposure may still provide a method for separating a component of higher specific weight from a component of lower specific weight of a fluid. The method may include channeling the fluid through a separating curve arranged between an inlet duct and a separator outlet duct, and expelling at least part of the highest specific weight component and at least part of the lower specific weight through openings in the separation curve. The method may also include derivating the portion of the lower specific weight component expelled through the openings back into the separation curve, and maintaining a substantially constant cross-sectional area of the flow at least in the inlet duct and the curve separation.

[0007] The present exhibition is best understood from the detailed description below, when dealing with the associated figures. It is emphasized that, according to industry standard practice, several features are not designed to scale. In fact, the dimensions of the various resources can be arbitrarily increased or reduced, for clarity of discussion.

[00011] It is to be understood that the following presentation describes several example modalities for the implementation of different resources, structures or functions of the invention. The example modalities of components, arrangements and configurations are described below for simplification of the present exhibition; however, these exemplary embodiments are provided as examples only and are not intended to limit the scope of the invention. In addition, the present exhibition may repeat reference numbers and / or letters in the various example modalities and through the figures provided here. This repetition is for the sake of simplicity and clarity, and in itself does not dictate a relationship between the various example modalities and / or configurations discussed in the various figures. Furthermore, the formation of a first resource on or in a second resource in the description that follows may include modalities in which the first and second resources are formed in direct contact, and may also include modalities in which additional resources can be formed. interposing the first and second resources, so that the first and second resources may not be in direct contact. Finally, the example modalities presented below can be combined in any combination of forms, that is, any element from an example modality can be used in any other example modality, without departing from the scope of the exhibition.
[00012] In addition, certain terms are used throughout the description below and in the embodiments for reference to particular components. As someone skilled in the art will appreciate, several entities may refer to the same component by different names and, as such, the naming convention for the elements described here is not intended to limit the scope of the invention, unless specifically defined otherwise on here. In addition, the naming convention used here is not intended to distinguish between components that differ in name, but not in function. In addition, in the following discussion and in the embodiments, the terms "including" and "comprising" are used in an open-ended manner, and thus should be interpreted to mean "including, but not limiting". All numerical values in this exhibit may be exact or approximate values, unless specifically stated otherwise. Therefore, several types of exhibition can deviate from the numbers, values and ranges shown here, without deviating from the intended scope. Furthermore, as used in the embodiments or in the specification, the term "or" is intended to involve exclusive and inclusive cases, that is, it is intended that "A or B" is synonymous with "at least one of A and B ", unless expressly specified otherwise here.
[00013] Figure 1 illustrates a cross-sectional view of an example separator 10, according to one or more modalities. The example separator 10 is a compact static separator and includes a process fluid inlet 12, a process fluid outlet 14 and a liquid outlet 15. The process fluid inlet 12 is connected to an external tube (not shown) ) or another type of conduit that connects to a source of process fluid (not shown). The process fluid outlet 14 can be connected to another external tube or conduit and, for example, possibly to a rotating separator of a compression system (not shown). In other example embodiments, however, the process fluid outlet 14 can be connected to or upstream of any other structures and / or devices. The process fluid inlet 12 can be connected fluidly to an inlet conduit 16, which can also be referred to here as an inlet pipe, and the process fluid outlet 14 can be connected fluidly to an outlet conduit 18, which can also be referred to here as an outlet tube. It will be appreciated that the term "tube" is not necessarily limited to a structure having a circular cross section, and other cross sections are contemplated here.
[00014] In at least one example embodiment, the inlet tube 16 and the outlet tube 18 can be removable and can include a top 17 attached to a base 19. The top 17 can be mechanically attached to the base 19 and can include a gasket or other sealing member (not shown). In other exemplary embodiments, the top 17 can be attached to a base 19, for example, by welding or other processes and / or devices. In addition, in at least one example embodiment, the inlet tube 16 and the outlet tube 18 can be arranged so that a portion of the outlet tube 18 can be located within the inlet tube 16, as shown. Also as shown, the outlet tube 18 can bend from vertical to horizontal, and can come out of the inlet tube 16 and connect to an external structure, as described above. It will be appreciated that directional terms such as "vertical", "horizontal", "above", "below", "sideways" and the like refer to relative positioning and / or orientation and are not meant to be limiting for this exhibition.
[00015] In other example embodiments, the outlet tube 18 can be arranged inside the outlet tube 18. The arrangement of one of the outlet tube 18 and the inlet tube 16 within the other can have the useful advantage of reducing the general size of the separator 10. However, example embodiments in which the outlet tube 18 extends away from the inlet tube 16, for example, in the opposite direction to that of the inlet tube 16, are contemplated here.
[00016] Still, in an exemplary embodiment, the liquid outlet 15 can be arranged below the inlet and outlet tubes 16, 18 to allow gravity to drain separate portions of a fluid flow. In another example embodiment, the liquid outlet 15 can be arranged above or to the side of the inlet and outlet tubes 16, 18, and can employ other drainage means, such as auxiliary pumps and / or a rupture vessel of integral gas with a liquid level control system (not shown).
[00017] Furthermore, the inlet tube 16 can include a bulge 20 where the inlet tube 16 has an increased radius. The inlet tube 16 may contain a portion of the outlet tube 18 in the bulge 20, so that, in the horizontal cross section, the unobstructed area of the inlet tube 16 remains substantially constant, despite partial obstruction by the outlet tube 18. "Substantially constant", as used here with reference to areas, is generally defined as meaning tolerant to variances of less than or equal to around +/- 10%.
[00018] The separator 10 generally includes an outlet duct 24, an inlet duct 26 and a separation curve 28 which together define a main flow path of the separator 10. In an example embodiment, the main flow path it can be substantially axisymmetric around a center line 54, and it can also have a flow area of substantially constant cross-section, as described in greater detail below with reference to figure 2.
[00019] The inlet tube 16 can be connected fluidly to the inlet duct 26, as shown. Inlet duct 26 can be substantially axisymmetric and can flex or turn away from centerline 54 near where inlet duct 26 is connected to inlet tube 16, and then can become tapered around from the center line 54. Inlet duct 26 can also have a cross section of annular inlet duct and can be oriented at an angle aa from centerline 54 of separator 10. In an example embodiment, the angle a it can be between around 60 degrees and around 80 degrees in relation to the center line 54, between around 65 degrees and around 75 degrees in relation to the center line 54, or around 70 degrees in to the center line 54.
[00020] The inlet duct 26 can be upstream of and fluidly connected to the separation curve 28, which will be described in greater detail with reference to figures 2 and 3. The separation curve 28 can be a curve of approximately 180 degrees , and can be axisymmetric around the center line 54. In addition, the separation curve 28 can be at least partially toroidal in shape around the center line 54. Additionally, the separator 10 can include a gas return channel 36 , which fluidly connects the liquid outlet 15 to the separation curve 28 near the inlet duct 26.
[00021] The outlet duct 24 can be downstream of and fluidly connected to the separation curve 28. The outlet duct 24 can have an annular outlet duct cross section and can be of a truncated shape around the center line 54 , similarly to the inlet duct 26, until it flexes to meet the outlet tube 18. The outlet duct 24 can be arranged at an angle β with respect to the center line 54, which can be substantially equal to the angle a. So that portions of the inlet and outlet ducts 26, 24 are substantially parallel; however, in other example embodiments, the angle P may be greater than or less than the angle a. For example, the angle P can be between about 65 degrees and about 85 degrees in relation to the center line 54. In addition, the inlet and outlet ducts 26, 24 can be at least partially concentric or substantially so in relation to each other. As can be appreciated, the concentric arrangement can provide the advantage of reducing the overall size of the separator 10.
[00022] Figure 2 illustrates an enlarged portion of figure 1, as indicated by the dashed box in figure 1. Inlet duct 26 has an inlet fluid inlet 50 that can be connected to inlet tube 16 and a fluid outlet outlet 56 which can be connected to the separation curve 28. In addition, the inlet duct 26 may have an outer wall 58 and an inner wall 60, which are spaced apart. The distance between the inner and outer walls 58, 60 can define a WI entry width. In any given horizontal cross section, the inlet duct 26 can still define an inlet radius Ri, with the inlet radius RI being the distance from the center line 54 to the center of the inlet duct 26. As illustrated, the WI inlet width can decrease from a maximum inlet fluid inlet 50 to a minimum in outlet fluid outlet 56. In addition, the inlet radius Rx can vary inversely with the inlet width WI, so the input radius RI increases as the WI input width decreases. The inlet radius RI can have a maximum inlet radius RI at the outlet fluid discharge 56 and a minimum inlet radius RI at the inlet fluid inlet 50. Therefore, the cross-sectional area through which a fluid can flow that is, the flow area of the inlet duct 26 can remain substantially constant. In addition, the inlet duct 26 can extend at an angle a, as described with reference to figure 1, until the inlet radius RI reaches a desired length, which can be, for example, three times the nominal radius of the tube inlet 16, at which point the outlet fluid discharge 56 from the inlet duct 26 can be connected to the separation curve 28.
[00023] The separation curve 28 can be connected fluidly to the inlet duct 26 at an inlet end 62, and can have a gas outlet end 64 which is connected to an outlet fluid inlet 66 of the outlet duct 24. Between the inlet end 62 and the gas outlet end 64, the separation curve 28 may include an inner surface 32 and an outer surface 34, with an outer body 41 of the separator 10 providing the outer surface 34.
[00024] The gas return channel 36 can be formed around the outside of the separation curve 28, so that the separation curve 28 can be arranged between the gas return channel 36 and the center line 54. The gas return channel 36 can include a passage 35, which can be at least partially toroidal around the outside of the separation curve 28 and can terminate at an injection interface 37. The injection interface 37 is fluidly connected to the curve separator 28 near the inlet end 62. In an example embodiment, the gas return channel 36 fluidly connects the liquid outlet 15 to the separation curve 28, and the injection interface 37 is a converging nozzle or an ejector, to help redirect a gas outflow, as described below.
[00025] The separation curve 28 may further include an auxiliary liquid outlet channel 40, which may include a ferrule 38 extending from the outer surface 34 towards the inner surface 32 and located near the gas outlet end. 64 of the separation curve 28. The auxiliary liquid outlet channel 40 can also include a liquid passage 42, which can extend, for example, through the outer body 41 to the liquid outlet 15, thereby fluidly connecting the ferrule 38 at liquid outlet 15.
[00026] The gas outlet end 64 of the separation curve 28 can be connected to the outlet fluid inlet 66 of the outlet duct 24. In the example embodiment, the outlet duct 24 can be formed similarly to the duct inlet 26. Therefore, outlet duct 24 may have an outlet fluid outlet 67 connected to outlet tube 18, and an inner wall 65. The inner wall 65 can be defined by a radial flow expander 22, which can form a flow expander peak 25, where a flow of fluid through outlet duct 24 flows out to outlet tube 18, thereby changing from a flow path with a ring-shaped cross section to one with a circular cross section. In an example embodiment in which the inlet duct 26 is inside the outlet duct 24, the radial flow expander 22 can be formed in the inlet duct 26, so that it defines the inner wall 60 of the inlet duct 26. In in such an embodiment, the peak flow expander 25 can form the beginning of the change in the shape of the cross section of the fluid flow from circular in the inlet tube 16 to ring-shaped in the inlet duct 26.
[00027] The inner wall 65 can be spaced from an outer wall 63 of the outlet duct 24 for defining an outlet duct width Wo. The outlet duct width Wo can increase from a minimum outlet duct width Wo at the outlet fluid inlet 66 to a maximum outlet width Wo at the outlet fluid outlet 67. Additionally, the distance from the center line 54 up to half of the outlet duct 24 can define an outlet duct radius Ro in any given horizontal cross section. In an example embodiment, the outlet duct radius Ro can decrease from the outlet fluid inlet 66 to the outlet fluid outlet 67 in an inverse proportion to the increasing outlet width Wo, so that the cross section flow area of outlet duct 24 remains substantially constant throughout.
[00028] Referring now to figure 3, an elevated perspective view of the outer surface 34 and the outer body 41 of the separation curve 28 is shown. In an example embodiment, the outer surface 34 has a region shaped like V or scallop shell 44. The scallop shell 44 region can have a peak 46 and a valley 48 defined there. Peak 46 can fit on inner surface 32 (not shown) and can help support outlet duct 24 (not shown). In other example embodiments, however, the peak 46 may not fit the inner surface 32. Valley 48 may have an opening 49, or slot, defined there. Opening 49 can extend through the outer body 41 until the passage of liquid 42, thereby dividing the outer body 41 into projections like claws 43. In another example embodiment, however, the opening 49 can be distinguished from the passage of liquid 42. The liquid passage 42 can extend around the edge 45 of the outer body 41 to the outlet of liquid 15. The opening 49 can also extend through the outer body 41, thereby fluidly connecting the inner surface 32 with the liquid outlet 15.
[00029] In an example embodiment, the outer surface 34 can include a plurality of scallop-shaped or V-shaped 44 regions, defined at intervals around the separation curve 28. A plurality of peaks 46 and a plurality of valleys 48 can each be defined on the outer surface 34, where each of the plurality of valleys 48 is defined between two of the plurality of peaks 46, as shown. In addition, in each of the plurality of valleys 48, one or more of the openings 49 can be defined, with one, a few or all of the openings 49 fluidly connecting the outer surface 34 with the liquid outlet 15.
[00030] In an example operation, with reference to figures 1 and 2, a multiphase fluid flows through the process fluid inlet 12 and into the inlet tube 16. The multiphase fluid can be characterized by a more specific weight component high, which can be referred to here as a "liquid", and a lower specific weight component, which can be referred to here as a "gas", it being desirable to separate the two components. It will be appreciated that, despite the naming convention chosen here for the two components, the higher specific weight component may additionally contain relatively dense solids and / or gases, and the lower specific weight component may additionally include liquids relatively light and / or solid. Therefore, the separator 10 can separate any higher specific weight component from any lower specific weight component.
[00031] In an example embodiment, to maintain a relatively fixed magnitude of the meridional velocity of the multiphase fluid flow, the radius of the inlet tube 16 increases in the bulge 20 to account for partial obstruction by the outlet tube 18, thus maintaining a substantially constant cross-sectional flow area. The multiphase fluid then flows to the inlet duct 26, where the cross-sectional flow area continues to remain substantially constant, despite the decreasing inlet width WI, due to the increasing inlet radius Rx. At outlet fluid discharge 56, the width of the multiphase fluid flow, as defined by the WI inlet width, has decreased to the point where the multiphase fluid flow is a relatively thin sheet.
[00032] The flow of multiphase fluid is then directed through the separation curve 28, which can be a relatively abrupt curve. The pressure drop coefficient is related to the ratio of the width of the multiphase fluid flow to the radius of the separation curve 28. A reduction in the flow width WI in the inlet duct 26, therefore, can reduce the pressure loss coefficient and / or allow a smaller radius of the separation curve 28. In an example embodiment, the head loss coefficient on the separation curve 28 can be approximately 0.74 or, in other words, approaching the head loss caused by a customary long curve.
[00033] Unlike a long curve, however, the inertial force felt by the multiphase fluid flow in the separation curve 28 can be, for example, equal to around 1800 times the force of gravity, which will generally be sufficient to separate the liquid from the multiphase flow. It will be appreciated, however, that the separator 10 can be designed so that other levels of inertial force can be obtained. The inertial force can force the liquid towards the outer surface 34 of the separation curve 28, where it can then be expelled through the openings 49 defined on the outer surface 34, through the outer body 41. Once expelled, the liquid can be channeled away from the separation curve 28 through the liquid outlet 15, using gravity or other means for draining the liquid, as described above with reference to figure 1.
[00034] As the liquid (and / or any other components with a higher specific weight of the flow) is centrifugally expelled through the openings 49, the scallop-shaped or V-shaped 44 regions (see figure 3 ) channel the gas through the separation curve 28 towards the gas outlet end 64. The scallop-shaped regions 44 can additionally prevent a return flow of gas through the inlet end 62. In some cases, a film of the liquid can be pushed, despite the centrifugal force, by the gas along the outer surface 34 and towards the gas outlet end 64. In an example embodiment including the auxiliary liquid outlet channel 40, as shown in the figure 2, the film can be collected by the ferrule 38, before the liquid exits through the gas outlet end 64. The liquid can then drain through the liquid passage 42 and through the liquid outlet 15, pushed forward by gravity or d additional devices, as described above.
[00035] A part of the gas that is intended to escape through the gas outlet end 64 can be expelled in a centrifugal way through the openings 49 together with the liquid. In fact, this can be an advantageous occurrence, as it can assist in channeling the liquid through the openings 49. The gas return channel 36 can be configured to return all or a portion of the gas that escapes through the openings 49. In In an example operation, the multiphase fluid flow in front of the injection interface 37 can create a decreased static pressure at the injection interface 37, which can create a pressure gradient at passage 35. This can act to siphon the gas expelled through the openings 49 for the liquid outlet 15 back through the passage 35 and for the separation curve 28 near the inlet end 62, thereby deriving the outflow of gas back into the multiphase fluid flow. In an example embodiment, the gas return channel 36 can be configured to return or drift around 5% or more of the total amount of gas that proceeds to the separation curve 28. Additionally, the liquid outlet 15 can include plates or other coalescent medium (none shown) for restricting the liquid at the liquid outlet 15 as to a migration to the gas return channel 36.
[00036] After passing through the separation curve 28, the multiphase fluid can consist of an increased percentage of gas and a reduced percentage of liquid, thus having an overall reduced specific weight. However, to maintain the desired low loss coefficient described above, the cross section of the multiphase fluid flow can be maintained at a substantially constant size. Thus, as the outlet radius Ro decreases, the outlet width Wo can increase to compensate and maintain the flow area of substantially constant cross section, until outlet duct 24 connects to outlet tube 18. The multiphase fluid flow then it can exit the separator 10 through the outlet tube 18, through the process fluid outlet 14 and, for example, to a rotary separator and / or a compressor.
[00037] Figure 4 illustrates an example method of separating a multiphase fluid flow into a high band frequency range and a lower specific weight component. The method of figure 4 can proceed by operating an example embodiment of the separator 10 shown and described above with reference to figures 1 to 3, or separators similar to these. The multiphase fluid flow can define an annular cross section, as determined by the shape of an inlet conduit through which the multiphase fluid flow can be
[00038] channeled. The annular cross section can have a radius that increases and a width that decreases, before the multiphase fluid flow encounters a separation curve, shown in 101. As such, the multiphase fluid flow can expand radially, while thinning in width, so that it becomes a thin sheet close to the separation curve, thereby allowing the radius of the separation curve to be small, while allowing the separation curve to produce minimal head loss, as described above.
[00039] The multiphase fluid flow can be channeled through the separation curve, shown in 102. Once on the separation curve, a portion of the lower specific weight component can be expelled through openings in the separation curve, shown in 103. The expelled portion of the lower specific weight component can be derived back to the separation curve, shown in 104, for example, by the gas return channel described above with reference to figures 1 and 2. The separation curve it also expels at least a portion, up to substantially all of the highest specific weight component through the openings, shown in 105. However, there may be a film remaining of the highest specific weight component left on the separation curve, even after the first expulsion . As such, the method can still include expelling the remaining film from the highest specific weight component, shown at 105, and can also do so through an auxiliary liquid outlet channel, as described above with reference to figure 2 The highest specific weight component expelled can then be drained, shown in 107, through a liquid outlet, such as that described above with reference to figures 1 and 2. In addition, the method may include avoiding a return flow from the multiphase fluid flow by channeling the multiphase fluid flow through the separation curve with a scallop-shaped region, as described above with reference to figure 3.
[00040] The lower specific weight component that is channeled through the separation curve, after that, can be channeled through an outlet conduit. The outlet conduit may have an increasing width and a decreasing radius, shown at 108. Once through the outlet conduit, the multiphase fluid flow, having a reduced amount of higher specific weight component, can proceed to other components of a compression system through an outlet, shown in 109.
[00041] While varying the radius and width of the multiphase fluid flow, shown in 101 and 108, and channeling it through the separation curve, shown in 102, the method may include maintaining a cross-sectional area substantially constant of the multiphase fluid flow, shown at 110. This can maintain a relatively constant magnitude of the meridional velocity of the multiphase fluid flow, and can have the advantage of minimizing head loss on the separation curve, as described above.
[00042] Therefore, the modalities of the exhibition can include a separator including an inlet duct that has an inlet flow inlet, an inlet flow discharge, an inlet width that decreases between the inlet flow inlet and the inlet flow discharge, and an inlet radius that increases between the inlet flow inlet and the inlet flow discharge; a separation curve fluidly connected to the inlet discharge from the inlet duct and including an outer surface that has a scallop-shaped region, and an opening formed on the outer surface; a liquid outlet fluidly connected to the opening of the separation curve; and an outlet duct having an outlet flow inlet connected to the separation curve, an outlet flow discharge, an outlet duct width that increases between the outlet flow inlet and the outlet flow discharge, and a outlet duct radius that decreases between the outflow inlet and the outflow outlet.
[00043] Exposure modalities can still provide the separator as described above, in which the inlet duct has a substantially constant cross-sectional flow area, and / or in which the inlet duct, the separation curve and the duct outlets have a substantially constant cross-sectional flow area. Exposure modalities can also provide the separator, as described, in which the opening of the separation curve is formed in the scallop-shaped region, and / or the separator as described above, further including: an inlet conduit connected to the inlet duct; and an outlet duct connected to the outlet duct and disposed at least partially in the inlet duct. Exposure modalities can provide the separator as described above, still including an auxiliary liquid outlet channel defined on the separation curve near the outlet duct and fluidly connected to the liquid outlet, and / or in which the liquid outlet channel auxiliary includes: a ferrule extending from the outer surface of the separation curve; and a liquid passage extending from the outer surface and fluidly connected to the liquid outlet. Exposure modalities can also provide the separator, as described above, still including a gas return channel fluidly connected to the liquid outlet and the separation curve, in which the gas return channel is configured to derive a gas flow from the liquid outlet to the separation curve near the inlet duct.
[00044] The modalities of the exhibition can also provide a separator including: an inlet tube; an inlet duct having an annular inlet duct cross section and fluidly connected to the inlet tube; a separation curve fluidly connected to the inlet duct and having a defined slit there; an outlet duct having an annular outlet duct cross-section, fluidly connected to the separation curve, and arranged at least partially concentric with the inlet duct; and a liquid outlet fluidly connected to the gap of the separation curve. Exposure modalities can still provide the separator as described above, in which the inlet and outlet ducts are at least partially truncated around a center line of the static separator, and the separation curve is at least partially toroidal around the center line. Exposure modalities can also provide the separator, as described above, in which the inlet duct is arranged at an angle of between about 60 and about 80 degrees in relation to the center line, and / or where the separation curve includes an external surface having a V-shaped region that includes a peak and a valley, and / or in which the slit is formed in the V-shaped region valley.
