| Installation and Operation of High Purity
CO Gas Recovery Plant Susumu Koizumi, Tuneo Fujita, Toshikazu Sakuraya |
| Synopsis: Mizushima Works installed a high purity CO gas recovery plant COPISA (CO pressure induced selective adsorption) and began its CO supply to a neighbouring chemical factory in July 1985. COPISA separates a high purity CO gas from the BOF gas by the PSA process. From the BOF gas, which consists mainly of CO, CO2 and N2, CO2 is adsorbed in the 1st stage adsorption, and CO is selectively adsorbed in 2nd stage adsorption. By this process, more than 98% high purity CO is recovered. Capacity of this plant is 410 Nm3/h, and product CO is used as raw material for synthetic chemistry and also as the bubbling gas in the steelmaking process. |
