STRUCTURE OF CRYOGENIC HIGH-PRESSURE PUMP FOR LNG

摘要

PURPOSE: A structure of a cryogenic high-pressure pump for LNG is provided to process evaporation gas in the cryogenic high-pressure pump without additional facility. CONSTITUTION: A structure of a cryogenic high-pressure pump for LNG is as follows. Evaporation gas which is generated by heat of a motor(13) within the cryogenic high-pressure pump for LNG is mixed with LNG within the cryogenic high-pressure pump for LNG using high pressure LNG which is extracted during the operation of a pumping unit of the cryogenic high-pressure pump for LNG. The evaporation gas is condensed and then flows into an inlet of the pumping unit.
