Production of iron through BF route is still a dominant route and coke is a major raw material and energy source for the blast furnaces. The process of coal carbonization in slot ovens is one of the major sources of atmospheric pollution in an Integrated Steel Plant. Coke making process involves coal preparation, carbonization and coke handling operations. To meet the demand of Blast Furnaces o...

The use of steel-making slag as catalysts for microwave-assisted dry reforming of CH4 was studied. Carbon materials (an activated carbon and a metallurgical coke), mixtures of carbon materials + Fe-rich slag and mixtures of carbon materials + Ni/Al2O3 were tested as catalysts. Mixtures of slag with carbons gave rise to higher and steadier conversions than those achieved over carbon materials. T...

The energy system in a modern integrated steel plant is a complicated network of units exchanging energy and matter with each other. System studies using process integration tools are important to avoid sub-optimization. At the steel plant in Luleå such studies have been carried out using a MILP-based mathematical programming tool (reMIND), mainly because of its inherent flexibility for handlin...
