The gas resource in iron & steel factory is very rich.One of gas utilization routes is methanol synthesization using gas,including BFG,LDG and COG,and in this way both the CO_2 reduction and the chemical products with high value can be obtained at the same time.In this paper,the technique route of BFG utilization for resource is put forward,and the environment and economy evaluation models are set up to analyze and estimate the CO_2 reduction and economic benefit of methanol synthesization by BFG and by gas off full- oxygen blast furnace.
