摘要：
A blast furnace gas discharged from a blast furnace is separated into gases containing various components using two-stage gas separation and refinement apparatuses. First, the blast furnace gas is separated into a gas containing H 2 , N 2 , and an unavoidable impurity gas component, a gas containing N 2 and an unavoidable impurity gas component, a gas containing N 2 , CO, CO 2 , and an unavoidable impurity gas component, and a gas containing CO, CO 2 , and an unavoidable impurity gas component with a gas separation and refinement apparatus of a first stage. Then, of these separated gases, the gas containing CO, CO 2 , and the unavoidable impurity gas component is separated into a gas containing CO and an unavoidable impurity gas component, a gas containing CO 2 and an unavoidable impurity gas component, and a gas containing CO, CO 2 , and an unavoidable impurity gas component with a gas separation and refinement apparatus of a second stage.
