Development of high purity CO gas recovery system for BOF gas by modified PSA process

Journal Article:

Abstract

COPISA process (where two processes for separating CO-adsorptive gases and desorbing desorption-difficult gas are added to conventional PSA gas separation process) is outlined. In two units of PSA, CO/sub 2/ gas is adsorbed and separated in first PSA unit. The gas excluding CO/sub 2/ is fed to second PSA unit, where CO is adsorbed and separated from N/sub 2/ and H/sub 2/, and then desorbed and recovered under reduced pressure. For optimizing the process, a pilot plant was operated for about 1000 hrs. in a half year. The results confirm possibility of simplifying pre-treatment of coal gas. CO-PSA pressure swing pattern suitable for elimination of Co-adsorptive N/sub 2/ is established. Recovery of CO gas is enhanced. Optimization of gas flow pattern between adsorption towers required for reduction in operating cost is performed. (7 figs, 1 tab, 8 refs)
