    摘要: A gaseous hydrocarbon stream (10) is cooled to produce a liquefied hydrocarbon stream (20). The gaseous hydrocarbon stream (10) is cooled in one or more heat exchangers (140a) using a first refrigerant from a first refrigerant circuit (100) in which said first refrigerant is compressed in a first compressor (110) driven by a first gas turbine (120) having a first inlet air stream (125) and liquefied using a second refrigerant circuit (200) wherein a second refrigerant is compressed in a second compressor (210) driven by a second gas turbine (220) and having a second inlet air stream (225). The cooling duty available in a stream of a chilled coolant (320) is divided over at least first (340) and second (350) parts in accordance with a common input parameter, and one or both of said first and second inlet air streams (125, 225) are cooled with the chilled coolant (320), whereby the cooling duty available in the first part (340) is used to cool the first inlet air stream (125), and the cooling duty available in the second part (350) is used to cool the second inlet air stream (225).

    摘要: A gaseous hydrocarbon stream (10) is cooled against a first refrigerant and a second refrigerant, to produce a liquefied hydrocarbon stream (20). The first refrigerant is cycled in a first refrigerant circuit (100), comprising compressing in a first compressor train(110) comprising one or more first compressors on a common drive shaft (215). The second refrigerant is cycled in a second refrigerant circuit (200), comprising compressing in a second compressor train(210) comprising one or more second compressors on said common drive shaft (215).The common drive shaft (215) is driven with one single gas turbine (220). A first inlet air stream (225) for combustion is cooled against a stream of a chilled coolant (320) and then passed to the single gas turbine (220).

    摘要: In a method and apparatus for treating a hydrocarbon stream (110) comprising methane, at least a part (130) of the hydrocarbon stream (110) and a main refrigerant stream (310) are cooled by indirect heat exchanging against a pre-cooling refrigerant (230). The pre-cooled hydrocarbon stream (140) is passed to a first inlet (151) of an extraction column (125), and an effluent stream (160) is discharged from the extraction column (125). The effluent stream (160) and at least a part of the pre-cooled main refrigerant stream (320) are passed to a further heat exchanger (175), where they are both cooled thereby providing a cooled methane-enriched hydrocarbon stream (180) and at least one cooled main refrigerant stream (410,430). Said passing of the effluent stream (160) to the further heat exchanger (175) and said passing of the pre-cooled hydrocarbon stream (140) to the first inlet (151) of the extraction column (125) comprises indirectly heat exchanging the effluent stream (160) against the pre-cooled hydrocarbon stream (140).
