In the process of steel production, a large number of blast furnace gas, converter gas, coke oven gas, rich in carbon monoxide, hydrogen and methane are valuable components, which are the main secondary energy sources of steel works. 55-60% of H2 is contained in coke oven gas, converter gas and blast furnace gas respectively containing 60% ~ 60% and ~25% CO, so steel exhaust completely can be used as a source of chemical synthesis of CO and H2 needed.

PIONEER, on the basis of its mature and leading PSA technology, according to the characteristics of blast furnace gas, developed the process of the formation of a unique CO separation technology of blast furnace gas, by which blast furnace gas can be used from the low cost of mass separation CO.


CO is a kind of important raw material with chemical synthesis. It can purify CO from the converter gas to over 99%, which is used for the production of ethylene glycol, acetic acid, dimethyl carbonate, polycarbonate, TDI, DMF and other chemical products, thus significantly enhancing the added value of the gas. To obtain CO by the use of converter gas has a large cost advantage. With the rapid development in the non-steel industry, it has attracted attention by many domestic and overseas famous iron and steel enterprises.

BFG to carbon monoxide

Separation of CO from blast furnace gas is an international problem, which is mainly due to the blast furnace gas also contains a large number of N2 and CO2. Because of the close boiling point of N2 and CO, the traditional cryogenic rectification process can not be used to separate CO from blast furnace gas. The adsorption of CO and N2 is low...
