Study on the non-coal high-energy-consumption chlor-alkali industry layout in China based on the development of the non-grid-connected wind power industry

The chlor-alkali chemical industry has high energy consumption and is facing a developmental bottleneck presently due to a shortage of energy. Realizing the coupling space layout between the large-scale non-grid-connected wind power industry and the chlor-alkali chemical industry, and establishing the non-coal high-energy-consumption chlor-alkali chemical industrial bases have the vital significance to the comprehensive utilization of wind energy and the sustainable development of the chlor-alkali chemical industry. Based on determining the spatial distribution of China´s large-scale non-grid-connected wind power industry by using development data of the social economy and of the wind power industry as of 2006, this paper studies the anticipated spatial layout frame of the non-coal high-energy-consumption chlor-alkali chemical industry in China by 2020 through overall consideration of the current situation and the planned objectives of the chlor-alkali chemical industry. The study shows that in 2020 China will form nine non-coal high-energy-consumption chlor-alkali chemical industrial bases including Jiangsu, Shandong, Zhejiang, Liaoning, Xinjiang, Inner Mongolia, Shanxi, Ningxia and Qinghai, which can generate 1 713.94times108 kilowatt hours of electricity, save 2149.84times104 tons of raw coal, reduce dust emission by 202.82times104 tons, reduce carbon dioxide emissions by 4056.31times104 tons, reduce nitrogen oxides emission by 20.28times104 tons, and reduce sulfur dioxide emissions by 32.45times104 tons, which are produced from burning coal, and thereby improve both economic efficiency and environment benefits.
