FUEL GAS SUPPLY SYSTEM OF LIQUEFIED NATURAL GAS OPERATED IN AMBIENT TEMPERATURE

摘要

A fuel gas supply system of LNG(Liquefied Natural Gas) operated in normal temperature is provided to save manufacturing and maintenance costs by replacing material of a compressor from low temperature material to normal temperature material, and to improve performance and efficiency of the compressor by installing a fuel gas cooling device to a discharge unit of the compressor. A fuel gas supply system of LNG(Liquefied Natural Gas) operated in normal temperature comprises a normal temperature heater(30), a compressor(40) and a fuel gas cooler(41). The normal temperature heater heats low temperature fuel gas generated in a droplet removing device(22). The compressor compresses the fuel gas heated in the normal temperature heater so as to supply the fuel gas to a use device(60). The fuel gas cooler adjusts the fuel gas so as to have temperature demanded in the use device by lowering temperature of the fuel gas increased by compression of the compressor.
