Method and apparatus for cooling a gaseous hydrocarbon stream |
摘要 |
<p>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). The single gas turbine (220) is a multiple shaft gas turbine with a shaft power for mechanical drive of at least 40 MW, comprising at least one auxiliary turbine (180) and at least one inlet air compressor (160) mechanically connected to the auxiliary turbine (180) via a first internal shaft (22), and a power turbine (190) drivingly engaged with the common drive shaft (215), which power turbine (190) is separately rotatable from the first internal shaft (22).</p> |
