Title:
NATURAL GAS RELIQUEFACTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/122349
Kind Code:
A1
Abstract:
The present invention relates to a natural gas reliquefaction system capable of increasing a reliquefaction amount of evaporation gas generated from natural gas through ultra-low temperature cooling. Provided is a liquid gas reliquefaction system comprising: a storage tank in which natural gas is stored; a compression apparatus for compressing evaporation gas generated in the storage tank through a supply line and returning the compressed evaporation gas to the storage tank through a return line; a first heat exchanger installed to perform heat exchange between the supply line and the return line and primarily cooling the evaporation gas of the return line; a constant pressure valve installed between the storage tank and the first heat exchanger on the return line for decompression; and a second heat exchanger installed in front of or at the rear of the constant pressure valve on the return line and secondly cooling the primarily cooled evaporation gas by an ultra-low temperature cooling circuit.
