Author/Source: China Chemical Industry News Date: 2009-4-8 -------------------------------------------------------------------------------- Recently, the Coking Coal Company of Henan Coal and Chemical Industry Group launched four key projects in the field of chemicals and circular economy, including a project for producing 1,000 tons of polysilicon per year, a project for producing 200,000 tons of ion-exchange membrane caustic soda per year, a new dry-process cement production line with a capacity of 4,500 tons per day, and the Zhao Gu No. 2 Mine project. The project with an annual production capacity of 1,000 tons of polysilicon requires a total investment of 790 million yuan; it can generate annual sales revenue of 1 billion yuan and profits and taxes of 400 million yuan. The scale of the project’s construction is 1,000 tons per year; it includes a facility for producing vapor-phase silica at a rate of 2,000 tons per year, as well as a hydrogenation unit with a capacity of 1,000 tons per year, enabling the on-site conversion of silicon tetrachloride, which is a by-product of polysilicon production. At present, the project with an annual production capacity of 300 tons has been built and is in trial production, while the second phase with an annual capacity of 700 tons is under active preparation. An investment of 576 million yuan is planned for this year, with trial production set to begin in November. The total investment for the project to produce 200,000 tons of ion-exchange membrane caustic soda per year is 979 million yuan. The construction scope includes production facilities for 200,000 tons per year of ion-exchange membrane caustic soda, 40,000 tons per year of liquid chlorine, 60,000 tons per year of hydrochloric acid, 60,000 tons per year of trichlorosilane, and 50,000 tons per year of chloroacetic acid. The construction period is 14 months. This year, an investment of 128 million yuan is planned, with production set to begin in September 2010. The annual sales revenue is expected to reach 1 billion yuan, while profits and taxes will amount to 300 million yuan. The new dry-process cement production line with an annual output of 4,500 tons requires a total investment of 514 million yuan. It is an important project for the Coking Coal Company in promoting a circular economy and building harmonious mining areas. This year, 146 million yuan is planned to be invested in this project, with operations set to begin in June 2010. The project is expected to generate annual sales revenue of 350 million yuan and profits and taxes of 100 million yuan. The designed production capacity of Zhao Gu No. 2 Mine is 1.8 million tons per year, with a service life of 55.5 years. The estimated investment for this project is 1.692 billion yuan; 292 million yuan is planned to be invested in 2009. Operation is scheduled to begin in September 2010, with annual sales revenue of 900 million yuan and profits and taxes of 450 million yuan.
Does the coking coal company also produce polysilicon? Where should the location be chosen? Please let those who know inform me.
Could you please inform me about the production process for this polysilicon project?
The polysilicon produced from coking coal is manufactured by Jiaoke Coal Group HeliJing Technology Co., Ltd., located in the industrial cluster area of Zhongzhan District in Jiaozuo; a 300-ton production facility has been put into operation there.
With so many projects involving polysilicon being launched across the country, its price has already dropped significantly. Will there still be profits if more projects are launched? Why does China rush to launch projects in such a herd-like manner?
