And installation procedures for providing gaseous carbon monoxide and / or a mixture containing carbon monoxide.

摘要

A process for supplying gaseous carbon monoxide and / or gas mixture containing at least 10% carbon monoxide in which: a) a gas (1) feed containing carbon monoxide as at least one of its components main and preferably at least one of nitrogen, methane and hydrogen as other principal components is purified using an adsorption step in one of at least two adsorbent beds (3) to produce a purified feed gas to be sent a separation unit b) the separation unit separates the feed gas to produce gaseous carbon monoxide, wherein the gaseous carbon monoxide is a final product (37) and / or a gas mixture (73) is a product end containing at least 10% carbon monoxide, possibly by mixing gaseous carbon monoxide (72) with at least one other gas (71) from the separation unit c) liquid carbon monoxide is stored in a re cipiente (47) storage, d) liquid carbon monoxide is withdrawn from the storage vessel and at least part (61) of the liquid is vaporised to produce gaseous carbon monoxide, forming carbon monoxide gas at least part of the product of gaseous carbon monoxide and / or being mixed with another gas to form at least part of the gaseous mixture containing at least 10% carbon monoxide, characterized in that the withdrawal and vaporisation of liquid carbon monoxide take place during at least part period at the beginning of the adsorption step before the adsorbent bed is saturated with carbon monoxide and optionally i) if there is a reduction in the amount of feed gas sent to the separation unit, and / or ii) when the product requirement exceeds the maximum capacity of the separation unit.
