Title:
RE-LIQUEFACTION SYSTEM OF EVAPORATIVE GAS AND SHIP
Document Type and Number:
WIPO Patent Application WO/2018/230950
Kind Code:
A1
Abstract:
The present invention relates to a re-liquefaction system of an evaporative gas and a ship. The present invention comprises: an evaporative gas compressor for compressing an evaporative gas, generated in a liquefied gas storage tank, in multiple stages and supplying the same to a source of demand; an evaporative gas heat exchanger for exchanging heat between the evaporative gas compressed in the evaporative gas compressor and the evaporative gas introduced into the evaporative gas compressor; a decompression valve for decompressing the evaporative gas heat-exchanged by the evaporative gas heat exchanger after being compressed by the evaporative gas compressor; and a gas-liquid separator for gas-liquid separating the evaporative gas decompressed by the decompression valve, wherein the present invention further comprises a high-temperature evaporative gas delivery line for delivering a high-temperature evaporative gas, discharged from the evaporative gas heat exchanger, from an upstream side of the decompression valve to a source of demand of low pressure when a lubricating oil used in the evaporative gas compressor of a high-pressure stage is mixed with the evaporative gas and introduced into the evaporative gas heat exchanger, and the high-temperature evaporative gas, compressed by the evaporative gas compressor, is injected into the evaporative gas heat exchanger in order to remove the lubricating oil introduced into the evaporative gas heat exchanger.
