FUEL GAS SUPPLY SYSTEM

摘要

PURPOSE: A fuel gas supply system is provided to minimize energy required for re-liquefying BOG and vaporizing LNG by heat-exchanging high temperature BOG with ultra-low temperature LNG. CONSTITUTION: A fuel gas supply system comprises a compressor(110), a condenser(120), a high pressure pump(130), and a B/L heat exchanger(140). The compressor compresses Boil-Off Gas generated inside an LNG storage tank. The condenser re-liquefies the compressed BOG into LNG. The high pressure pump compressed the re-liquefied LNG. The B/L heat exchanger heat-exchanges the BOG with the compressed LNG.
