Abstract
A liquefied gas treatment system according to an embodiment of the present invention includes a boil-off gas heat exchanger exchanging heat between boil-off gas, pressurized by a boil-off gas compressor and recovered along a boil-off gas supply line branching off upstream of a liquefied gas-consuming unit, and the boil-off gas supplied from a liquefied gas storage tank, wherein the boil-off gas heat exchanger cools the boil-off gas, recovered along the boil-off gas supply line, with the boil-off gas, supplied from the liquefied gas storage tank, or flash gas, supplied through a vapor recovery line.

8. A liquefied gas treatment system, comprising:
-
a boil-off gas supply line connected from a liquefied gas storage tank to a liquefied gas-consuming unit; a boil-off gas compressor provided on the boil-off gas supply line and pressurizing boil-off gas generated from the liquefied gas storage tank; a boil-off gas heat exchanger provided upstream of the boil-off gas compressor on the boil-off gas supply line and exchanging heat between the boil-off gas, pressurized by the boil-off gas compressor and recovered along the boil-off gas supply line branching off upstream of the liquefied gas-consuming unit, and the boil-off gas supplied from the liquefied gas storage tank; a boil-off gas decompressor provided downstream of the boil-off gas heat exchanger on the basis of a flow of the boil-off gas, recovered along the boil-off gas supply line, and decompressing the boil-off gas pressurized by the boil-off gas compressor; a vapor-liquid separator separating flash gas from the boil-off gas decompressed by the boil-off gas decompressor; and a vapor recovery line connected from the vapor-liquid separator to the boil-off gas heat exchanger and supplying the flash gas to the boil-off gas heat exchanger, wherein the flash gas separated in the vapor-liquid separator is heat-exchanged with the boil-off gas recovered along the boil-off gas supply line, and is joined on the boil-off gas supply line provided between the liquefied gas storage tank and the boil-off gas compressor. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
