LNG BOG RELIQUEFACTION SYSTEM

摘要

PURPOSE: A re-liquefaction system for LNG(Liquefied Natural Gas) and BOG(Boil Off Gas) is provided to reduce power consumption without using power for transferring the LNG and the BOG from a re-condenser to a pipe line. CONSTITUTION: LNG discharged from an LNG storage tank(110) pass through a re-condenser(130). BOG compressed in a BOG compressor(120) passes through the re-condenser. The BOG is liquefied again. The LNG which passes through the re-condenser and the compressed BOG are mixed using a mixing apparatus(150). Synthetic gas is transferred to a high pressure pump(160) for the LNG.
