摘要： The separation energy requirement of a conventional cryogenic process for separating carbon monoxide ("CO") from a gaseous feed containing primarily CO and hydrogen is reduced by an improvement to the process. In the process, CO is scrubbed from a vapor portion of the feed by a liquid methane wash and dissolved hydrogen is stripped from the resultant CO-loaded liquid methane stream. The hydrogen-stripped CO-loaded liquid methane stream is sub-cooled and split into at least first and second substreams. The first substream is expanded and introduced into a CO/methane fractionation column as a liquid feed. The second substream is partially vaporized and introduced into said fractionating column as a two-phase feed. The fractionating column separates the hydrogen-stripped CO-loaded liquid methane feeds to provide CO-rich vapor overheads and methane-rich bottoms liquid. A "high pressure" CO recycle heat pump stream provides reboil to the fractionation column. The improvement consists of providing part of the heat duty required to partially vaporize the second substream by heat exchange of the second substream against an "intermediate pressure" CO recycle heat pump stream of a pressure intermediate that of the CO-rich vapor overheads and the high pressure CO recycle heat pump stream.

摘要： Hydrogen (4), and carbon monoxide (21) are separated from a gaseous mixture thereof, typically a mixture of essentially hydrogen, carbon monoxide and methane (1) using liquid methane (3) to dissolve carbon monoxide in a methane wash column (2), removing (8) residual hydrogen (15) from the loaded methane wash (6,9), and separating (18) the residual loaded methane into carbon monoxide and methane fractions (21,22). The residual hydrogen (15) is removed in a hydrogen stripping column (8), said column being refluxed with a methane rich scrubbing liquid stream (13) withdrawn from an intermediate location of the methane wash column (2).

摘要： Carbon monoxide is separated from a gaseous mixture containing hydrogen and methane and contaminated with nitrogen by scrubbing carbon monoxide from a vapor portion of the feed by a liquid methane wash; stripping dissolved hydrogen from the resultant CO-loaded liquid methane stream; fractionating the resultant hydrogen-stripped CO-loaded liquid methane stream to separate nitrogen therefrom; and fractionating the resultant nitrogen-freed bottoms liquid into CO product overheads vapor and methane bottoms liquid. If the gaseous mixture also contains argon, argon content can be removed with the methane content to obviate a separate argon-separation stage as required by prior art processes.

摘要： The molar ratio of hydrogen and carbon monoxide in synthesis gas is changed by partially condensing at least a portion of the feed gas and separating the partially condensed feed mixture by non-fractionating phase separation. Preferably, the partially condensed feed mixture is separated by a first phase separation into a first liquid stream and a first vapor stream; the first vapor stream is partially condensed and separated by a second phase separation into a second liquid stream and a second vapor stream; the second vapor stream is warmed and expanded to provide refrigeration and partial condensation; and the expanded partially condensed stream is separated by a third phase separation to provide a third liquid stream and a third vapor stream. The synthesis gas product is at least partially derived from the third liquid stream and a portion of the third vapor stream.

摘要： Hydrogen and carbon monoxide are separated from a condensate-containing gaseous mixture thereof by using (a) a “first” stripping column (8) to remove the hydrogen content of the CO-loaded methane stream (6) obtained by washing CO from the gaseous mixture, or the vapor portion from a phase separation thereof, ascending a methane wash column (2) and (b) a “second” stripping column or a flash separator (30) to remove the hydrogen content of the feed gas condensate (9) obtained from the methane wash column (2), or the phase separation. The vapor stream (32) from the second stripping column or flash separator (30) is fed to the first stripping column (8). The liquid stream from the first stripping column and the liquid stream (33) from the second stripping column or flash separator (30) are fed (16, 17, 19 & 20; 34 to 39) to different locations of a separation column (18) providing a gaseous carbon monoxide product stream (21) and a liquid methane wash recycle stream (3). The process improves the efficiency of the separation by avoiding dilution of the CO concentration of the feed gas condensate (9) with the CO-loaded methane stream (6) which occurs in prior art CO/hydrogen separations using a methane wash.

摘要： Carbon monoxide is separated from a gaseous mixture containing hydrogen and contaminated with nitrogen by separating hydrogen and carbon monoxide contents to provide a carbon monoxide-enriched nitrogen-containing stream and separating carbon monoxide and nitrogen contents of said stream in a nitrogen-separation column to provide a nitrogen-enriched overheads vapor and a nitrogen-freed bottoms liquid. The overheads vapor is washed with liquid nitrogen to remove carbon monoxide therefrom and the resultant carbon monoxide-enriched liquid nitrogen is returned to said column as additional reflux. The liquid nitrogen wash simultaneously reduces the loss of carbon monoxide with the nitrogen-enriched vapor and provides refrigeration to the process. When the gaseous feed is a synthesis gas also containing methane, the methane and carbon monoxide contents can be separated before or after separation of the nitrogen and carbon monoxide contents.
