Abstract:
A gas production plant comprising:a gas source providing a feed gas stream having a first gaseous component and a second gaseous component; a first separator fluidly coupled to the gas source, wherein the first separator removes at least part of the first gaseous component from the feed gas stream, thereby producing a first offgas stream and a first product stream predominantly comprising the first gaseous component; a second separator fluidly coupled to the first separator, wherein the second separator removes at least part of the second gaseous component from the first offgas stream, thereby producing a second offgas stream and a second product stream predominantly comprising the second gaseous component; a liquefaction unit fluidly coupled to the first and second separator, wherein the liquefaction unit receives at least part of the first product stream and at least part of the second offgas stream to produce a third product stream predominantly comprising liquefied first gaseous component; and wherein the liquefaction unit produces a third offgas stream of which a first portion is combined with the first offgas stream, and of which a second portion is used as a non-waste gas.
