The ULCOS blast furnace process aims at reducing the CO2emission of the blast furnace by 50% in two steps:
Decrease of carbon consumption by recycling most of the top gas after CO2removal, which requires operating the blast furnace with pure oxygen;
Underground storage of CO2.
The first stage is essential to demonstrate the feasibility of this new process. It has been tested over a 6 week campaign at the LKAB experimental BF in Luleå. The facility was adapted specifically for the trials (including the erection of a VPSA plant). Different operating conditions were investigated. In conclusion, and taking into account underground storage, the CO2emission at the blast furnace was reduced by up to 76%. For the steelmaking plant, this should result in a net CO2-savings of 65% at the level of the hot rolled coil. |
