<P>PROBLEM TO BE SOLVED: To obtain a higher purity product gas in the case of separation and recovery by adsorbing the product gas by an adsorbent. <P>SOLUTION: A raw gas containing carbon monoxide is supplied to adsorption towers 16A, 16B and then carbon monoxide is separated and recovered by desorbing carbon monoxide from the adsorbent. At this time, the pressure of the adsorption towers 16A, 16B is reduced by an ejector 18 operated with steam as a primary fluid (driving fluid) and carbon monoxide (secondary fluid) desorbed from the adsorbent together with steam (primary fluid) is discharged while carbon monoxide is sucked into the ejector 18. Then, the discharged fluids are cooled to an ordinary temperature or near and steam is condensed. The discharged fluids are thereby vapor-liquid separated and carbon monoxide, a gas component, is recovered as the product gas. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
