Carbon capture,
utilization and storage
of CO2 emissions
Danieli technologies make possible carbon capture from BF, BOF, as well as from DRI plants and reheating furnaces operating with natural gas, when these cannot be avoided or reduced directly.
The most effective technology applied today for CO2 storage and utilization is related to Enhanced Oil Recovery -EOR where the CO2 is collected from the industrial plant, compressed, and transported via pipeline and then injected into oil wells to improve their productivity. A relevant part of the injected CO2 will be trapped in the well, contributing also to the storage.
Danieli adopts the CO2 chemical absorption for carbon capture in BF, BOF, natural gas DRI process gases, reheating furnaces and in electrical arc furnaces.
Energiron direct reduction plants feature built-in CO2 capture, and for example, the carbon dioxide captured in the two DRI plants at Emirates Steel, in the United Arab Emirates, is used locally for oil extraction by EOR.
Energiron ZR CO2 capture plant. One of the major advantages of the Energiron DRI technology is the selective elimination of CO2 which can be further commercialized as by-product.
In BF/BOF operations, for conventional air pollutant clean-up (SOx, NOx, PM), the flue gas enters a Danieli Corus absorber reactor and flows counter-currently to a CO2-lean solvent. There, CO2 is absorbed into and reacts with the Mono Ethanol Amine -MEA to form water-soluble compounds. The treated flue gas (mostly nitrogen) is discharged to the atmosphere and the CO2-rich solution is pumped to a stripper reactor for regeneration.

Another Danieli original development allows CO2 capture of flue gases from electric steelmaking and reheating furnace processes, using micro-algae to make a product that can be turned into a biofuel, or utilized in pharmaceutical manufacturing. Such technology has been already implemented in an industrial pilot plant.
