Clean Technology : Limit and Limitation

Lahiri, A K and Aggarwal, Kajal (2002) Clean Technology : Limit and Limitation. In: Clean Technologies for Metallurgical Industries (EWM - 2002), 24-25 January, 2002, CSIR - National Metallurgical Laboratory, Jamshedpur.



The limiting of pollutant emissions from COREX and Romelt processes, non-recovery coke ovens and coke less cupola have been calculated using equilibrium analysis. The results show that main pollutants present after full utilization of the exit gases from all the processes are sulfur dioxide and nitric oxide. The former is dependent on the volatile sulfur present in the fuel and later depends on temperature of combustion and amount of air used for combustion. Lowering of combustion temperature and closer control of combustion can reduce NO load signi-cantly.
