Practices and research on C02 emission reduction m iron and steelmaking
Emission of carbon dioxide from steel making is a global problem,mainly caused by the usage of coal and coke in the blast furnace.Many international projects with the objective to develop breakthrough technologies are performed worldwide,dealing with this problem.Still,an integrated steel plant is a very energy efficient production system,where off gases from one production unit can be used as a fuel in another unit.It is also clear that optimization of one process unit from CO2 0r energy point of view does not necessarily give an optimization of the whole production system.Expanding the system boundary might also reveal new insights and new optimal solutions.At Swerea MEFOS Research Institute in Lulea,in northern Sweden,pilot plant research has been performed in the LKAB Experimental Blast Furnace,to facilitate the development of new breakthrough technologies.Furthermore a new advanced analysis approach has been developed through an Institute Excellence Center,PRISMA ( Process Integration in Steel Making) in close cooperation with the mining and steel making industry in the Nordic countries.This paper will highlight some of the studies on C02 mitigation from iron ore based steelmaking being performed for short and long term perspective,including the effect of different system boundaries.In addition,more recent research activities performed at Swerea MEFOS will also be presented.
