Abstract:
A bottom-up PM emission model was developed based on the production technologies and PM emission control devices in Chinese cement industry. Through analyzing the historical distribution of technologies in cement producing and the impact of standards on PM emission control from cement industry, emission factors of cement industry in China during 1990-2004 were generated by this technology-based model, and emission inventories were developed thereby. Emission factor decreased from 27.9 kg x t(-1) cement in 1990 to 8.05 kg x t(-1) cement in 2004. Emissions of PM from cement industry in China reached the peak value in 1997, with 1044 x 10(4) t of TSP, 716 x 10(4) t of PM10, 436 x 10(4) t of PM2.5 emitted, then decreased until 2001, and increased slowly again during 2001-2004. The distribution of PM emissions among provinces is uneven. Shandong, Guangdong, Hebei, Jiangsu, Zhejiang, and Henan contribute more than 50% of emissions of China. Rapid spread of pre-calcining kilns in China and implementation of Emission Standard of Air Pollutants for Cement Industry in 2004 will probably decrease PM emissions from cement industry to a large extent, leading to obvious variation on PM pollution characteristics in China.
