A TREATMENT SYSTEM OF LIQUEFIED NATURAL GAS

摘要

The present invention relates to a liquefied natural gas (LNG) treatment system comprising: an LNG supply line connected to a first consumer from an LNG storage tank; a pump pressurizing LNG discharged from the LNG storage tank; a heat exchanger; a plurality of boil-off gas compressors; and a cold and heat generating device generating power as a cooled working fluid rotates a turbine. The LNG treatment system according to the present invention can improve energy efficiency as generated energy can be used as a power source for another device, by generating the energy using LNG discharged from the LNG storage tank or waste cold and heat energy of boil-off gas as a power source of the cold and heat generating device.
