Abstract:
1. A liquefaction plant comprising: a first flow path defined and configured for sequential delivery of a first stream of natural gas through a compressor, a first side of a first heat exchanger and a first side of a second heat exchanger; a second flow path defined and configured for sequential delivery of a second stream of natural gas through an expander, a second side of the second heat exchanger and a second side of the first heat exchanger; and at least two paths including a cooling path having a first expansion valve therein and a liquid production path having a second expansion valve therein formed from the first flow path at a location subsequent an intended flow of the first stream of natural gas through the first side of the second heat exchanger, wherein the cooling path selectively is defined and configured to direct at least a first portion of the first stream of natural gas to the second side of the second heat exchanger and wherein the liquid production path is defined and configured to selectively direct a second portion of the first stream of natural gas to a gas-liquid separator.
