The plant comprises an adsorbent-filled tank (8) permanently interposed in the line (2), between the purification unit (3), operating by adsorption of solidifiable impurities from the gas mixture (5) containing carbon monoxide, and the cryogenic separation unit which delivers pure carbon monoxide at its outlet (6). The adsorbent in the tank (8), advantageously the same as the adsorbent in the adsorbers (4A, 4B) of the purification unit (3), 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 (4A, 4B) of the separation unit (3).
