A device for regasification of LNG, and cogeneration of fresh water and dry air, having a casing hermetically sealed from the exterior withstanding vacuum conditions, and containing a working fluid in its liquid and gaseous phases; the casing is traversed by t a cryogenic tube through which LNG is fed and regasified natural gas is collected via the other end. The external surface of the cryogenic tube condenses the gaseous working fluid, releasing energy, and evaporative condenser tubes located outside the casing, with the external condensing surface in contact with damp air, and the air vapor contained in the damp air condenses thereupon, generating cold fresh water and releasing energy to the working fluid in its liquid phase which flows through the evaporative condenser and which evaporates, generating a gaseous phase working fluid, which exits through the evaporative condenser and is directed into the casing for the condensation

The present invention relates to a technology for liquefying natural gas, which is subsequently transported by rivers and oceans and ultimately regasified. Pretreated natural gas is compressed by a compressor 1, the heat of compression is removed in an air or water cooler 2, and multi-stage pre-cooling is subsequently performed by evaporating a heavy refrigerant in an evaporator 3. The light refrigerant vapor and its pre-evaporation cold are recovered in a shell-and-tube heat exchanger 7, where the pressure of the gas to be liquefied is reduced by a pressure reducer 10, unliquefied gas is separated, and liquefied natural gas is discharged. The heavy refrigerant obtained by evaporation is compressed by a compressor 4, condensed in an air or water cooler 5, and reused in the multi-stage pre-cooling of natural gas. A light refrigerant is compressed by at least two compressors 11, the heat of compression is removed in an air or water cooler 12, and then passes through continuous cooling by a low-pressure light refrigerant in a double-flow superheater 12 and an evaporating heavy refrigerant in an evaporator 3. The high-pressure light refrigerant is then split into two streams. The first stream is expanded through an isentropic process in an expander 14. The second stream passes through continuous cooling in a shell-and-tube heat exchanger 7, then expanded through an isenthalpic process in a throttle valve 15, and evaporated by subcooling natural gas in an evaporator 8. The streams are then mixed at equal pressure and used as a single stream of low-pressure light refrigerant to cool the second stream of light refrigerant before expansion and evaporation in the isenthalpic process with natural gas in the shell-and-tube heat exchanger 7, and to cool a single stream of high-pressure light refrigerant in a double-flow superheater 13. The present invention provides stronger cooling of the natural gas, reduces the amount of boil-off gas and the work required for its recompression and recycling, and provides a simpler hardware design for the heat exchanger.
