Abstract:
1. A plant comprising: a compressor that is configured to compress a feed gas comprising a first component and a second component, and to thereby form a compressed feed gas having a first pressure; a cooler coupled to the compressor, wherein the cooler is configured to receive and cool the compressed feed gas to a temperature sufficient to condense at least part of the first component in the compressed feed gas; a first separator that is configured to separate the cooled compressed feed gas into a first vapor portion and a first liquids portion, and an expander that is configured to expand the first vapor portion to a second pressure to thereby allow formation of an expanded stream; and a second separator that is configured to separate the expanded stream into a second liquids portion and a second vapor portion, wherein the cooler is configured to allow the second vapor portion to provide refrigeration to the compressed feed gas.
