    DESCRIPTION

    Mini-plant or modular LNG plant in Skids improved.

    Object of the invention 5

    The present invention relates to the adaptation of Regasification Satellite Plants (PSRs) as a mini-plant or Modular Plant of Liquefied Natural Gas in a Skids-like structure or chassis to facilitate its removal or transfer.
     10
    Solves the problem of the long delay that exists at the time of the assembly of a PSR, around three months, of which, 2 or 3 weeks would be for civil works, and the storage volume margins of 0 are extended, 5m3 to 200 m3, as well as vaporization, from 5 Nm3 / h to 6,000 Nm3 / h.
     fifteen
    Likewise, the conditions in which the gas is stored have been improved, by means of a tank of Liquefied Natural Gas at a pressure greater than 1 bar and at a temperature of -196 ° C.

    When, for some reason, the PSR must be removed or moved, the equipment must be disassembled from the plant to equipment, and the loading, transport and unloading to its new location, 20 equipment by equipment, must be carried out.

    The mini-plants object of the present invention are placed on a structure that can be made of steel, concrete or any material that withstands cryogenic temperatures, of adequate dimensions for road, rail and sea transport, and never exceeding 25 meters of 4.5 meters. height, for easy loading, transport and unloading in trucks. The truck arrives at the final location, and should only be left on the concrete floor. It would only be necessary to connect to the gas network, after its cold and commissioning.

    The advantages of this invention are as follows:

    - Minimize work in the field, so that it would be reduced from more than 2 months of work in the field (with the exception of civil works), to 3 days. In 3 days, after the completion of the civil works, the final customer would have the plant fully installed and underway. 35

    - Installation Transfer in one or several Skids. The plant would be loaded, transported and unloaded in a new location as if it were a container.

    - Reduce civil works. The equipment is concentrated in a smaller space, so that the civil work to be carried out is reduced, and they can also be better adapted to locations where compliance with the safety distances of the UNE 60210/2015 standard is quite limited. It is not necessary to make shoes, only a concrete screed, since the weight of the equipment is distributed in the structure or support frame. Four. Five

    - Facilitates assembly in locations that are difficult to access, or exports to other countries. It is an ideal product for locations outside the peninsula, due to the increased cost of products and transport, such as the Canary Islands. It would facilitate access to this Energy to the inhabitants and industries of the Islands. fifty

    - The number of Skids is increased and therefore the storage, reaching up to 5 Skids, and with storage volumes between 0.5m3 to 200 m3.

    - The conditions in which the gas is stored are improved, by means of a tank of Liquefied Natural Gas at a pressure greater than 1 bar and at a temperature of -196 ° C.

    The industrial application of this invention is within the manufacture, assembly and installation of LNG plants and more specifically of LNG mini-plants in Skids. 5

    Background of the invention

    Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related thereto.

    Document ES0322535A3 describes a tank truck for transporting compressed and liquefied carbon dioxide at low temperature, which the tank is formed by a special steel casing. The aforementioned invention refers to the compressed and liquefied carbon dioxide anhydride container 15 at low temperature while the main invention contemplates an entire transportable LNG plant with all its equipment and elements.

    ES2245863A1 refers to a mobile LNG / CNG supply station, of the type comprising a tanker truck for subsequent provisioning and refueling between a main terminal station and a satellite or secondary station, connecting any geographical supply point from any main terminal of the inland territory or of the coast, which consists of a mobile equipment formed by a tank truck that is provided with a series of components for the supply of LNG and CNG that comprise at least the LNG container itself, a transfer tank of LNG that keeps the LNG in the conditions to carry out the refueling of gas, a high pressure pump that allows to obtain the CNG from the LNG, a set of several high pressure cylinders, a high pressure vaporizer that vaporizes the LNG heating it to room temperature to be supplied to a CNG tank, some measured flow res (CNG and LNG), and a control panel with PLC technology that automatically performs and safely resupplies gas operations and receives and transmits signals for control and operation; in combination with a circuit of circulation and control of fluids and / or electrical-electronic signals between said components. The main invention, unlike said invention, can be both transported and installed autonomously, ready for a new displacement or removal if necessary. 35

    ES2235646A1 proposes a mobile LNG regasification plant, which comprises the basic elements related to the tank, vaporizer, odorizer and others, which constitute a fixed satellite plant for liquefied natural gas regasification, which consists of a mobile equipment comprising a plurality of elements components mounted as a compact unit 40 on a platform and / or semi-trailer dragged by a tractor unit to the place of delivery, and whose unit operates autonomously, whose plurality of component elements comprises a series of main elements consisting of a tank -cryl LNG cryogen, an atmospheric vaporizer preferably with a finned tube, a primary and secondary gas low temperature safety valve, outlet pressure regulator 45, THT odorizer canister, and a pneumatically operated valve; Instrumentation elements consisting of pressure transmitters / tank level and safety probe / thermostat related to gas temperature; and a control panel that receives the signals of the level of the tank, pressure of the tank and the temperature of the gas through the instrumentation elements and that sends the actuator signals of sending compressed air 50 for the supply of the gas by closing the fluodynamic circuit corresponding, whose plurality of main elements and instrumentation and the control panel constitute a circuit unit in which the liquefied natural gas stored in the tank-tank is supplied to the atmospheric vaporizer in which by heat exchange with the environment
    it is gasified, then regulated to the supply pressure, and finally odorized by partial saturation of the gas flow; whose pneumatically operated valve cuts off the gas supply when the gas temperature drops too much. The proposed main invention can not only be transported but it is mounted on Skids to be installed on any concrete screed. 5

    Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does.

    The LNG mini-plant in Skid object of the present invention is constituted from a structure of steel or other material that withstands cryogenic temperatures, of dimensions suitable for road, rail and sea transport, and never exceeding 4.5 meters of height, for loading, transporting and unloading in trucks comprising the following 15 equipment or parts: a storage tank for Liquefied Natural Gas, where Liquefied Natural Gas is stored at a pressure greater than 1 bar and at a temperature of -196 ° C ; a discharge system whereby the tanks carry out the discharge of LNG into the storage tank; Atmospheric vaporizers (aluminum tube coil) separated from the tank, where LNG is passed from liquid to gaseous state, either by contact with the temperature of the atmosphere that heats the air, or it can be supported by electric or water reheaters hot, and in addition the vaporization can also be forced, passing the water through a container full of hot water, supported by boilers; a safety valve (VSF), which cuts off the supply if the temperature of the gas in its path is below -10 ° C, or below that recommended by the manufacturer to ensure the integrity of the materials located downstream; a regulating and measuring equipment that regulates the inlet pressure (from the tank) at a given outlet pressure (that required by the receiving network); and a system of odorization to give natural gas the characteristic smell it has.

    The LNG mini-plants object of the present invention can range from storage of 30 0.5m3 to 200 m3, and from a vaporization of 5 Nm3 / h to 6,000 Nm3 / h. The mini-plants can be configured from 1 to 5 Skids, depending on the LNG storage and the gasification capacity. These Skids are joined by flexible cryogenic hoses or cryogenic pipes, with their corresponding supports.
