A method for producing a CO-enriched gas from a feed gas comprising carbon dioxide (CO), at least one component selected from H, N, CH, CO, Oand argon, water vapor, optionally impurities such as NOx and/or SOx , and a solid-particle concentration of between 0.01 and 100 mg/m, wherein the feed gas is at least partially dried upstream of a PSA unit in order to prevent the solid particles from caking in the PSA unit is provided.

Dust-laden wet gas treatment

A method for purifying or separating a gas mixture comprising at least one fuel, using a unit having at least one adsorber subjected to a pressure cycle comprising at least one step of placing under vacuum by means of a vacuum pump, wherein at least one adsorber and/or the vacuum pump, depressurized during the cycle, is repressurized at least partly by an external gas to said unit and not containing a sufficient quantity of oxidizer to create an inflammable mixture during this repressurization.
