Title:
METHOD AND APPARATUS FOR SEPARATING BLAST FURNACE GAS
Document Type and Number:
WIPO Patent Application WO/2009/116671
Kind Code:
A1
Abstract:
Provided is a method and apparatus for separating blast furnace gas in which blast furnace gas emitted from a blast furnace is separated into gases that comprise various elements, by means of two stages of a gas separation and refinement apparatus. First, the first stage of the gas separation and refinement apparatus separates the blast furnace gas into: a gas comprising H2, N2, and unavoidable impurity gas components; a gas comprising N2 and unavoidable impurity gas components; a gas comprising N2, CO, CO2 and unavoidable impurity gas components; and a gas comprising CO, CO2, and unavoidable impurity gas components. Next, the second stage of the gas separation and refinement apparatus separates, the gas comprising CO, CO2, and unavoidable impurity gas components into a gas comprising CO and unavoidable impurity gas components; a gas comprising CO2 and unavoidable impurity gas components; and a gas comprising CO, CO2, and unavoidable impurity gas components.
