Title:
BOIL-OFF GAS RE-LIQUEFYING SYSTEM AND SHIP COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/043030
Kind Code:
A1
Abstract:
The present invention relates to a boil-off gas re-liquefying system and a ship comprising same. The system for treating a liquefied gas of heavy hydrocarbon comprises: a compressor for compressing a boil-off gas, generated in a liquefied gas storage tank, in multiple stages; a condenser for condensing the boil-off gas which has been compressed by the compressor; an intercooler for exchanging heat between some and the rest of the liquefied boil-off gas which has been condensed by the condenser, transferring a gaseous boil-off gas generated by means of the heat exchange to the compressor, and transferring the liquefied boil-off gas to the liquefied gas storage tank; and a liquefied gas pump for applying pressure to the liquefied gas in the liquefied gas storage tank, wherein the liquefied gas pump transfers the liquefied gas to the intercooler such that the gaseous boil-off gas in the intercooler is liquefied.
