초록 ▼

A process for the liquefaction of natural gas is disclosed wherein expansion valves for low-level multicomponent refrigerant and liquefied gas product streams are replaced with process-loaded turboexpanders having liquid inlet streams. Each turboexpander is coupled with a compressor or pump so that expansion work extracted from a given stream is used directly to compress or pump the stream prior to cooling and expansion. The use of process-loaded turboexpanders reduces the minimum work of liquefaction and increases the liquefaction capacity of the process.

대표청구항 ▼

A process for liquefying a pressurized gaseous feedstream comprising the steps of: (a) compressing said pressurized gaseous feedstream in a first compressor from a first pressure to a second pressure to yield a compressed feedstream; (b) cooling and liquefying said compressed feedstream by indirect heat exchange with a first and a second vaporizing multicomponent refrigerant stream in a cryogenic heat exchanger; (c) expanding the resulting liquefied feedstream of step (b) in a first expander wherein expansion work from said first expander drives said first compressor; and (d) withdrawing a liquefied gas product from said first expander; whereby the utilization of the expansion work of said first expander to drive said first compressor allows the liquefaction of said feedstream at said second pressure, which reduces the minimum work of liquefaction per unit volume of said feedstream compared with the liquefaction of said feedstream at said first pressure, and thus increases the liquefaction capacity of said process for a fixed refrigeration compressor power to generate said first and second multicomponent refrigerant streams.
