Boil-Off-Gas Processing system and BOG Processing method in Floating Gas Power Plant

摘要

According to one embodiment of the present invention, there is provided an evaporation gas treatment system for a floating gas power plant. Evaporation gas treatment system of a floating gas power plant according to an embodiment of the present invention, at least one liquefied gas storage tank for storing the liquefied gas therein, and the liquefied gas stored in the liquefied gas storage tank is generated by natural vaporization A power generation unit for generating electric power by receiving at least one of natural evaporation gas (nBOG) and forced evaporation gas (fBOG) generated by forcibly vaporizing liquefied gas stored in a liquefied gas storage tank as fuel gas, and receiving power from the power generation unit. It includes a re-liquefaction unit for driving the supplied and re-liquefying the natural evaporation gas to supply to the liquefied gas storage tank, the remaining amount is supplied to the power generation unit of the total amount of natural evaporated gas generated in the liquefied gas storage tank and the remaining remain liquefied gas storage Stored in the tank to maintain the internal pressure of the liquefied gas storage tank within the permissible range and exceed the permissible range of the liquefied gas storage tank; Which it may be fed to the re-liquefaction unit.
