Production of hot hydrogen-rich syngas in integrated plants for efficient injection in the blast furnace and CO2 mitigation
The main objective of the project is to adapt an existing pilot plant on industrial site for the production of hot H2-rich syngas by dry-reforming of coke oven gas and/or natural gas with hot CO2 from oxy-combustion of coke breeze or alternative solid C sources.
- Design the reforming process to be flexible in terms of input streams and to produce optimum syngas for direct injection in the blast furnace, resulting in significant reduction of its coke rate and associated CO2 emissions.
- Realization of the pilot tests that will demonstrate the reforming process and will provide sufficient and reliable data to extrapolate the operating results to the industrial scale.
- Assessment of the reduction of coke rate and associated CO2 emissions based on the long-lasting experience of the steel industry with gas injections in the BF, and more specifically by using the reference models and the practical experience of the involved partners.
- Realization of a complete evaluation of the industrial applicability of the reforming process, and the evaluation of alternative applications of the syngas, with detailed CO2 calculation, environmental life-cycle analysis (LCA) and economic evaluation.
