PROBLEM TO BE SOLVED: To achieve both of impurity removal and collection of COin a dry type gas purification facility.SOLUTION: Steam is obtained by supplying water to a humidifying device 27, and CO is shift reacted with COby the obtained steam in a shift reaction device 28 for collecting CO. Without reducing heat efficiency and complicating the facility, removal of impurities such as a halogen compound, a sulfur constituent, an ammonia component, a mercury and the like, and collection of carbon dioxide (CO) are performed. |
