SYSTEM FOR PROCESSING LIQUEFIED GAS IN SHIP

摘要

Disclosed is a system for processing a liquefied natural gas in a ship, comprising a storage tank for storing liquefied natural gas, and an engine using the liquefied natural gas stored in the storage tank as a fuel. The system for processing the liquefied gas comprises: a first stream comprising an evaporation gas that is generated from the liquefied natural gas inside the storage tank and then discharged from the storage tank; a second stream comprising the evaporation gas from the first stream which is supplied to the engine as the fuel; and a third stream comprising the evaporation gas from the first stream that is not supplied to the engine. The first stream is compressed by a compression device and then branched into the second stream and the third stream. The third stream is heat exchanged with the first stream in a heat exchanger and then liquefied, thereby processing the evaporation gas without using a reliquefication device that uses an additional coolant.
