Natural gas liquefaction plant and power supply equipment for natural gas liquefaction plant

摘要

The gas turbine equipment during rated load operation of 72 which possesses the turbine which turns the compressor 74 which compresses the air in the power supply equipment 71 for the natural gas liquefaction plant which supplies power to the natural gas liquefaction plant which liquefies the natural gas which separates the impurity with natural gas purification equipment 70, the compressed air and the fuel from the compressor burning, the combuster 75 which forms the combustion gas, by the combustion gas from the combuster and gas turbine equipment, the cold source supply system 85 which is supplied to gas turbine equipment carbon dioxide which are separated from the natural gas with natural gas purification equipment as a coolant of gas turbine equipmentIt has. Because the hot part of gas turbine equipment can be cooled sufficiently with this with carbon dioxide from cold source supply system, it is possible to improve reliability without decreasing the output and efficiency of gas turbine equipment.
