摘要：
Disclosed herein is a boil-off gas treatment system. The boil-off gas treatment system includes a compressor compressing boil-off gas generated in an LNG storage tank of a ship or a floating structure, a heat exchanger cooling the compressed boil-off gas through heat exchange with boil-off gas to be supplied to the compressor, an expansion unit performing adiabatic expansion of the boil-off gas cooled by the heat exchanger, a gas-liquid separator performing gas/liquid separation of the boil-off gas subjected to adiabatic expansion by the expansion unit and supplying liquefied natural gas to the LNG storage tank, and a bypass line through which the boil-off gas subjected to adiabatic expansion is supplied from a downstream side of the expansion unit to a downstream side of the gas-liquid separator.
