The plant comprises an adsorbent-filled tank permanently interposed in a line between a purification unit operating by adsorption of solidifiable impurities from a gas mixture containing carbon monoxide, and a cryogenic separation unit which delivers pure carbon monoxide at its outlet. The adsorbent in the tank advantageously the same as the adsorbent in the adsorbers of the purification unit has an affinity for carbon monoxide, thus making it possible to reduce the cyclic variations in the carbon monoxide production delivery rate which results from the cyclic operation of the adsorbers of the separation unit. This plant permits a simple, efficient and inexpensive regulation of the carbon monoxide production in such a plant, while greatly limiting production losses.
