A pilot-scale study of selective desulfurization via urea

2016-11-8  The iron ore sintering process is the main source of SO 2 emissions in the iron and steel industry. In our previous research, we proposed a novel technology for reducing SO 2 emissions in the flue gas in the iron ore sintering process by adding urea at a given distance from the sintering grate bar. In this paper, a pilot-scale experiment was carried out in a commercial sintering plant.

Desulphurization of pig iron using calcium carbide based

2009-11-20  While desulphurization can still be achieved with iron temperatures of slightly below 1300°C, temperatures of 1350°C give better desulphurization and reagent efficiencies. The higher temperatures also reduce the slag viscosity with a reduction of iron trapped in the slag. If the slag contains significant levels of metal oxide, the calcium carbide can react with the oxygen in the oxide first, reducing the reagent efficiency and this should be compensated for. Reduction of iron

A pre-study of Hot Metal Desulphurization

2012-11-26  At the steel plants of SSAB in Sweden, the production is iron ore-based and the pellets used in the blast furnace are from LKAB. Thus, this implies a high content of titanium and vanadium compared to the other pellet types. Coke is used in the blast furnace to reduce iron ore and it is one of the major sources of sulfur coming to the hot metal.
