AIR-COOLED TYPE LIQUEFIED GAS PRODUCTION FACILITY

摘要

Provided is an air-cooled type liquefied gas production facility having an air-cooled type liquefied gas production section for producing a liquefied gas by liquefying a supply gas containing methane as the main component. In the air-cooled type liquefied gas production facility, the air-cooled type liquefied gas production section comprises: a heat exchanger for cooling the supply gas by subjecting the supply gas to heat exchange with a refrigerant; a compressor for compressing a refrigerant evaporated by the heat exchange with the supply gas; air-cooled heat exchangers for cooling the compressed refrigerant by subjecting the compressed refrigerant to heat exchange with air; an expansion section for cooling the cooled refrigerant by expanding the cooled refrigerant; and a pipe rack section having the air-cooled heat exchangers arranged at the vertically uppermost part thereof. The pipe rack section has arranged in the space thereof located vertically below the air-cooled heat exchanger: tubing for delivering the supply gas to the heat exchangers; tubing for delivering the compressed refrigerant to the expansion section; and tubing for delivering the expanded refrigerant to the heat exchanger. The vertical length of the space is greater than the transverse length of the space when viewed from above.
