A TREATMENT SYSTEM OF LIQUEFIED GAS

摘要

The present invention relates to a liquefied gas treatment system comprising: an evaporated gas supply line which supplies evaporated gas by connecting a high pressured source of demand from a liquefied storage tank; and an evaporated gas compressor which is provided on the evaporated gas supply line in multiple stages and pressurizes the evaporated gas in multiple stages, wherein an upstream side stage of the evaporated gas compressor includes two or more cylinders. According to the present invention, the liquefied gas treatment system allows to optimize and use available fuel stored in a ship depending on a situation of the ship, thereby reducing waste of the evaporated gas and saving fuel costs of the ship according to an effective use of energy to be consumed by the ship.
