Abstract
Systems and methods for pre-cooling a natural gas stream to a liquefaction plant. A system may include a compressor configured to receive a first natural gas stream at a first pressure and produce a second natural gas stream at a second pressure; an exchanger to cool the second natural gas stream; and an expander to receive the cooled natural gas stream and expand the cooled natural gas stream to produce a chilled natural gas stream. The refrigeration content of the refrigerant is used to liquefy and sub-cool the natural gas stream to produce liquefied natural gas in a cold box or cryogenic exchanger. The refrigerant may be an external gas or an internal refrigerant working fluid expanded and compressed in a twin compander arrangement and compressed by a refrigerant compressor, or an external single mixed refrigerant working fluid compressed by a refrigerant compressor and expanded thru a JT valve.
