Direct emissions from integrated BOF plants typically amount to 1.8-3.0 tonnes CO2 per tonne of steel produced. DRI-based EAF plants emit approx. 2-3 tonnes CO2 per tonne of steel if they are coal based, or 0.7-1.2 tonnes/tonne if they are gas-based. Emissions from scrap based EAF plants are mostly indirect –the CO2 emissions are not produced ...

During 1990-2000, the Pb emission in Zhejiang Province increased slightly and the emission rate was only about 2500 t·a -1 . Non-ferrous metal mining contributed about 55% in this period. After 2000, Pb emission increased sharply and reached at a high stable value of 35000 t·a -1 after 2014, which was 14 times of 1990.
Using these emission factors, we estimated the net emission increases induced by the additional coal use at 2.7% (6.7 Gg) for primary PM 2.5, 5.4% (18.2 Gg) for SO 2, 0.5% (2.5 Gg) for NO x, and 3.4% (143.5 Gg) for CO in the four southern provinces in the heating period 2017, discarding the uneven distribution of the additional coal use between ...
Coal is the most important primary energy in China. Although the proportion of coal in China's total energy consumption continues to decline it will still be the main energy in China for a long time in the future. As the largest contributor to China's greenhouse gas emissions, the energy conservation and emission reduction of coal industry will be the most …

Emission Factors And Preparing AP-42 Sections" (March 6, 1992). Test reports containing sufficiently high quality data ratings were combined with existing data to revise emission factors or to produce new emission factors, as appropriate. When sufficient new data were obtained that were of higher quality than existing data, old
Sakamoto and Tonooka (2000) pointed out the emission factor of CO 2 from integrated steel plants was approximately 3.8 times higher than that from EAF route mills in Japan. Based on this assumption and the discussion above, we could estimate the total energy consumption and carbon emission caused by the crude steel production of China were 13 ...
