Method and apparatus for liquefying a hydrocarbon stream

A method and apparatus for liquefying a hydrocarbon stream (10) such as natural gas. The method comprises the steps of: (a) compressing the hydrocarbon stream (10) using one or more compressors (12) driven by one or more steam turbines (14) to provide a compressed hydrocarbon stream (20); (b) heat e...

Zusammenfassung:	A method and apparatus for liquefying a hydrocarbon stream (10) such as natural gas. The method comprises the steps of: (a) compressing the hydrocarbon stream (10) using one or more compressors (12) driven by one or more steam turbines (14) to provide a compressed hydrocarbon stream (20); (b) heat exchanging the compressed hydrocarbon stream (20) against one or more refrigerant streams (40) to fully condense the compressed hydrocarbon stream (20) and provide a liquefied hydrocarbon stream (30) and one or more warmed refrigerant streams (50); (c) compressing at least one of the warmed refrigerant stream(s) (50) of step (b) using one or more compressors (18) driven by one or more gas turbines (22); and (d) at least partly driving one or more of the steam turbines (14) of step (a) using steam provided by one or more of the gas turbines (22) of step (c).
