Title:
ENDOTHERMIC GAS LIQUEFACTION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/040190
Kind Code:
A1
Abstract:
An endothermic gas liquefaction device and a gas liquefaction method thereof. The device comprises a gas liquefaction system, a temperature converting device (2) and a condenser-evaporator (1), wherein the gas liquefaction system is used for transferring the heat of a gas to the condenser-evaporator (1) to form a liquid state; the condenser-evaporator (1) is internally provided with a system working medium for heat exchange with the gas liquefaction system, wherein the system working medium absorbs the sensible heat of the gas in the gas liquefaction system and then converts same into low-temperature steam; and the temperature converting device (2) is used for converting the low-temperature steam in the condenser-evaporator (1) into high-temperature steam, and transferring a part of the heat of the high-temperature steam, wherein after the energy of the high-temperature steam in the temperature converting device (2) is transferred, the steam is cooled into a liquid and is returned to the condenser-evaporator (1) for circulation repeatedly. The invention is free of the feeding and discharging of raw materials and the generation of contaminants, and air separation is performed on an environmental gas.
