CO.sub.2 and SO.sub.2 emission characteristics of the whole process industry chain of coal processing and utilization in China

The total coal consumption in China is on the rise. The characteristics of CO.sub.2 and SO.sub.2 emissions in the whole process of coal processing and utilization in China are worthy of study. Based on the five links of the whole process of coal production and utilization, including coal production, raw coal processing, logistics and transportation, conversion and utilization and resource utilization, this paper summarized and analyzed the energy consumption and pollutant emission sources of these five links, combined with the US Environmental Protection Agency's AP-42 method and IPCC method, to calculate total pollutant discharge and emission factors, where the emission factors were corrected by conversion efficiency. At the same time, uncertainty analysis is performed about CO.sub.2 and SO.sub.2 emissions. The results showed that CO.sub.2 emissions were 3.657 billion tons, and emission reductions were 61 million tons, and SO.sub.2 emissions were 4,844,500 tons, and emission reductions were 10.3595 million tons in 2015.
