Processes, Год журнала: 2024, Номер 12(2), С. 370 - 370

Опубликована: Фев. 10, 2024

To reduce pollution and improve the efficiency of coal resource utilization, this study proposed an integrated process for smelting reduction ironmaking gasification. A multi-zone constrained mathematical model, based on heat mass balance calculations, was developed to predict energy material flows required produce 1 ton hot metal. Two scenarios were examined: one using pure O2 as gasification agent (referred non-hydrogen-rich process) other a combination steam hydrogen-rich process). In non-hydrogen rich process, PCR (Post Combustion Ratio) varies from 0% 8%, total consumption, volume exported gas decrease by 57%, 57% 53%, respectively. H2 content increases 30% 50%, 38%. The upper limit in SRV (Smelting Reduction Vessel) off-gas is mainly determined PCR, which decreases 52.7% 45.2% 8%. findings work can serve theoretical basis further investigation new process.

steel research international, Год журнала: 2025, Номер unknown

Опубликована: Фев. 18, 2025

In light of global climate crisis, it is imperative to implement measures aimed at reducing energy consumption and carbon emissions in the iron steel industry. This study focuses on development innovative methodologies for minimizing during production, with particular emphasis synergistic optimization both long‐ short‐flow steelmaking processes. A flow model has been constructed analyze material flows associated long‐process (BF–BOF) short‐process (electric arc furnace (EAF)) steelmaking, as well assess potential reduction through industrial symbiotic technologies. The findings illustrate that S2 scenario, where proportion EAF increased 50%, are reduced 1,464.12 kg tcs, representing an 18.9% decrease. lower than achieved by traditional steelmaking; symbiosis technologies, such chemical production coke oven gas hydrogen can facilitate additional 41.33 tcs. offers a new pathway reference green transformation
