Abstract:
The blast furnace (BF) process is the most energy efficient way to reduce iron ore to primary steel thanks to its large scale and low thermal losses. However, as it is operated on fossil coal, novel approaches are required in order to drastically reduce its carbon footprint in an economic way.To reach this goal, ArcelorMittal is building a large demonstration plant which integrates two innovative approaches: “Pre-treatment and injection of cellulosic waste streams to create a biogenic feedstock for renewable reductant injection in the BF and thus displace fossil coal”; “Biological fermentation of the carbon monoxide waste gas of the BF into Ethanol to avoid the incineration of the carbon monoxide. The use of the bio-ethanol in other sectors (transport, chemicals) will displace fossil oil or natural gas”. A first of a kind plant is currently under construction at ArcelorMittal in Gent in which biocoal will be produced from torrefaction of wood waste. The key objective of this project is to validate how this biocoal technology can be used in a production representative environment which is a large-scale industrial steel mill, including the introduction and impact on the BF operation. The innovation deals with both the selection of the waste streams, the environmental friendly conversion into biocoal, the gasification of the biocoal in the BF and finally also the production of advanced bio-ethanol from the waste gas of the BF.
