摘要： A method for producing liquefied natural gas (LNG). A natural gas stream is directed to a mechanical refrigeration unit to liquefy the natural gas stream and form a pressurized liquefied natural gas (LNG) stream with a pressure greater than 50 psia (345 kPa) and less than 500 psia (3445 kPa). A liquid refrigerant subcooling unit is provided at a first location. Liquid refrigerant is produced at a second location that is geographically separate from the first location. The produced liquid refrigerant is transported to the first location. The pressurized LNG stream is subcooled in the liquid refrigerant subcooling unit by exchanging heat between the pressurized LNG stream and at least one stream of the liquid refrigerant to thereby produce an LNG stream.

摘要： A method of processing natural gas to produce liquefied natural gas using a consolidated refrigeration and liquefaction module. The natural gas is cooled in a first array of one or more heat exchangers using a first refrigerant from a first refrigerant circuit, wherein the first refrigerant is compressed in a first compressor. A second refrigerant from a second refrigerant circuit is compressed in a second compressor. The second refrigerant is cooled and partially condensed using the first refrigerant in a second array of one or more heat exchangers located in the consolidated refrigeration and liquefaction module. The partially condensed second refrigerant is separated into liquid and vapor phases using a refrigerant separator located in the consolidated refrigeration and liquefaction module. The natural gas is liquefied to produce LNG in a third array of one or more heat exchangers using the vapor and liquid phases of the partially condensed second refrigerant.

摘要： A liquefied gas treatment method for a vessel is performed by a liquefied gas treatment system for the vessel including a cargo tank storing LNG, and a main engine and a sub engine using the LNG stored in the cargo tank as fuel. The liquefied gas treatment system includes a compressor line configured to compress BOG generated in the cargo tank by a compressor and supply the compressed BOG to the engines as fuel, and a pump line configured to compress the LNG stored in the cargo tank by a pump and supply the compressed LNG to the engines as fuel. In a laden condition in which an amount of the LNG stored in the cargo tank is larger than in a ballast condition, the BOG generated in the cargo tank is supplied as fuel to at least one of the engines through the compressor line.
