Abstract
The invention relates to a method for separating a mixture comprising at least carbon monoxide, hydrogen, and methane. According to said method, the mixture is separated by a first separating means, at least one liquid fraction of the chamber of the separating means is sent to a product stripper, and at least part of the liquid fraction is sent from the product stripper to a CO/CHseparating column in order to produce a methane-enriched liquid flow and a gaseous flow enriched with carbon monoxide. The process is carried out under cold conditions at least partially as a result of a carbon monoxide cycle, said cycle at least partially ensuring the condensation at the top of the CO/CHseparating column and/or the reboiling in the chamber of the product stripper and/or the reboiling in the chamber of the CO/CHseparating column and/or the cooling of the mixture for the first separating means.
