Abstract
In a process for the purification of a gas flow containing NO, carbon dioxide and nitrogen, the gas flow is purified by adsorption in order to produce a flow enriched in carbon dioxide and in NOand depleted in nitrogen, the flow enriched in carbon dioxide and in NOand depleted in nitrogen is treated in a treatment unit in order to form a fluid enriched in NOwith respect to the treated flow, the fluid enriched in NOis sent to a catalytic conversion unit making possible the conversion of at least a portion of the NO, in the presence of oxygen and also of ammonia or of urea, to give nitrogen and water in order to produce a gas depleted in NOwith respect to the fluid enriched in NO, the catalytic conversion unit also being fed with a fluid having nitrogen as main component.
