<p>The present invention relates to a treatment system of a liquefied gas. According to an embodiment of the present invention, the present invention comprises: an evaporation gas compressor compressing a produced evaporation gas; a condenser making the evaporation gas compressed at the evaporation compressor exchange heat using a coolant; a coolant line installed to make the coolant circulate; a coolant compressor compressing the coolant through multi-stages; an evaporation gas decompressor decompressing the evaporation gas; a gas-liquid separator separating a flash gas; a gas recovery line supplying the flash gas to the evaporation gas compressor; and a coolant pre-cooling and pre-heating exchanger exchanging the coolant. According to the present invention, the coolant discharged from the condenser on the coolant line cools the coolant supplied to the condenser; thereby reducing an output of an expander due to a lower amount of inflow of the expander as the cooled coolant is cooled more by the flash gas supplied from the gas-liquid separator, and the volume of the coolant reduced.</p> |
