Abstract:
Provided is a method for separating blast furnace gas in which blast furnace gas emitted from a blast furnace is separated into gases of various elements using two stages of a gas separation and refinement apparatus. The first stage of the gas separation and refinement apparatus (S1) separates the blast furnace gas into a gas comprising carbon dioxide and unavoidable impurity gas components, and a gas comprising nitrogen, carbon monoxide, and unavoidable impurity gas components. The second stage of the gas separation and refinement apparatus (S2) separates the gas comprising nitrogen, carbon monoxide, and unavoidable impurity gas components which was separated by the first stage of the gas separation and refinement apparatus into a gas comprising nitrogen and unavoidable impurity gas components, and a gas comprising carbon monoxide and unavoidable impurity gas components.
