In a process for separating a mixture containing carbon monoxide, hydrogen and carbon dioxide, the mixture cooled in a heat exchanger is contacted by a stream of liquid methanol at a temperature below −40° C. to produce carbon dioxide enriched methanol and a carbon dioxide depleted gas relative to the cooled mixture, the carbon dioxide depleted gas is cooled in the heat exchanger and is sent to a separation unit to produce a carbon monoxide enriched stream and a hydrogen enriched stream and the streams enriched in carbon monoxide and hydrogen are heated in the heat exchanger by exchanging heat with the mixture.

Method and apparatus for separating a synthesis gas by cryogenic distillation

In a process of the separation of a mixture of carbon monoxide, hydrogen and methane, the mixture is sent to a scrubbing column, a bottom liquid withdrawn at the bottom of the scrubbing column is depleted in hydrogen with respect to the mixture and is sent to a stripping column, a bottom liquid from the stripping column is sent to a separation column and a liquid enriched in methane withdrawn from the bottom of the separation column is vaporized in order to form a final product.

Process and apparatus for the cryogenic separation of a mixture of carbon monoxide, hydrogen and methane for the production of CH4

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.

Method for separating a mixture of carbon monoxide, methane, hydrogen and optionally nitrogen by cryogenic distillation

A storage enclosure and an apparatus and method for producing carbon monoxide and/or hydrogen by means of cryogenic separation, including one such enclosure is provided.

Storage enclosure, method and apparatus for producing carbon monoxide and/or hydrogen by means of cryogenic separation, including one such enclosure

The invention relates to a method for producing carbon monoxide consisting, during an adsorption step, in using N adsorbers (A,B), wherein N is equal to greater than two, each of which follows, at an offset; the same period T cycle during which adsorption and regeneration phases succeed each other, in exposing, at the beginning of the adsorption phase, each adsorber to an eluting phase during which only a part of a nominal flowrate of the mixture is transferred to the adsorber until said adsorber is substantially carbon monoxide saturated while at least the second adsorber is maintained in the adsorption phase and a purified gaseous mixture is partially liquefied for producing a liquefied gaseous mixture, in storing said mixture in a capacity () and in transferring the liquefied gaseous mixture from the capacity to at least one column () for the separation thereof into a carbon monoxide rich product and, during at least one part of the adsorber eluting phases, the liquid level in the container is decreased and during at lest one part of the cycle outside of the eluting periods, said level is increased.
