Methanation – An Opportunity to Recycle Carbon and More Efficiently Introduce Hydrogen to the Blast Furnace?

Interest has grown among steel producers in blast furnace hydrogen injection to reduce coke rate and emissions intensity. Injecting hydrogen into the blast furnace has some inherent challenges, including limited utilization and heat balance difficulties. Injecting methane into blast furnaces, by contrast, is a well-understood technology. Methanation of carbon-containing steel plant offgases presents an opportunity to use hydrogen in the blast furnace. This approach has the added benefit of allowing carbon in the offgas to be recycled back to the process, rather than being emitted. The paper explores using synthetic natural gas as a blast furnace fuel.
