LIQUEFIED GAS PROCESSING SYSTEM FOR VESSEL Russian patent published in 2017 - IPC B63B25/16 

FIELD: gas industry.

SUBSTANCE: proposed is a liquefied gas processing system for a vessel, which includes a cargo tank storing liquefied natural gas and an engine using the liquefied natural gas stored in the cargo tank as fuel. Liquefied gas processing system includes: the first evaporating gas flow, which is formed from the liquefied natural gas in the cargo tank and is discharged from that tank; the second evaporating gas flow, which is supplied as fuel into the engine in the first flow; and the third evaporating gas flow, which is not supplied into the engine in the first flow. First flow is compressed in a compressor and then is divided into the second flow and the third flow. Third flow is liquefied by heat exchange with the first flow in a heat exchanger, as the result of which the evaporating gas is processed without the use of a repeated liquefaction device, which uses a separate cooler.

EFFECT: liquefied gas processing.
