Chemie Ingenieur Technik, EarlyView.The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases
Chemie Ingenieur Technik, EarlyView.A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Analysis on evaluation indicators of slagging in boilers co-firing coal with biomass
Reli fadianThe power generation by co-firing of coal and biomass is the most economical and efficient technology for existing coal-fired power plants to achieve CO2 emission reduction and large-scale efficient utilization of biomass. However, due to the significant

Influence of Slag Composition and Temperature on Slag Foaming.
ISIJ International, 1992 The slag foaming behavior caused by the reaction between FeO containing slag and hot metal was investigated for the CaO-SiO2-Al2O3-P2O5-TiO2-MnO-MgO-CaF2 system. The peak of slag foaming height was observed when (CaO)/(SiO2) was around 1.2 and the peak value of (CaO)/(SiO2) became slightly large with the increase in temperature and the CaF2 mixing ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This paper examines whether occupational pension funds (OPFs) apply a strategic and long‐term logic when assessing ESG practices in their investee firms. Using discourse analysis of semi‐structured interviews with asset managers and workers' representatives, we examine whether Spanish OPFs look beyond compliance‐driven CSR and consider the ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Research on supermarket‐related voluntary sustainability standards (VSSs) is divided on whether competition helps or hinders efforts to reduce negative social and environmental impacts. This paper examines how the standardization process shapes these outcomes.
