Current Situation and Abatement Potential of SO2 Emissions from Coke Making Industry in China

With the rapid development of iron and steel industry, high temperature coking has become an important application of coal. H2S of coke oven gas(COG) and its combustion products --SO2 has aroused more and more concern for the negative effects on environment and human health. The total coke production is about 335.53 Mt in 2007, and the caused SO2 emission is reported at about 181.19 kt. In reference to future development objectives and pollution control technologies of coking industry, the future reduction potential of SO2 emissions from coking is analyzed on the basis of coking technological progress, process improvement and industrial restructuring. It shows that the potential of SO2 emissions reduction will be 90.35 kt by 2010, and it will amount to 252.49 kt by 2015, which will be a good support to the energy-saving and emission-reduction targets of the country.
