Silicone By-Products for Best Emission Reduction

Cabot (China) Investment Co., Ltd. and Bluestar Chemical New Materials Co., Ltd. recently signed a contract in Beijing to expand the production capacity of fumed silica from Cabot Bluestar Chemicals (Jiangxi) Co., Ltd. The reporter learned from the Blue Star Chemical New Materials Company on January 26th that the project is most attractive to the industry. Blue Star Chemical New Material Company and Cabot Bluestar Chemical Company respectively use the by-products produced by the Other party as their own raw materials to recycle. The use of maximization of emission reductions, while bringing the chlorine utilization rate to 99.9%.
According to Zhang Xinsheng, Global Vice President of the Cabot Corporation and President of China, according to the current technological conditions adopted by most Chinese companies, the production of 400,000 tons of organic silicon will produce about 35,000 tons of monomethyltrichlorosilane. Monomethyltrichlorosilane is a substance that burns, is extremely toxic, and releases hydrogen chloride when it meets water. If it is discharged as waste, it will not only waste resources but also pollute the environment. Based on this, Cabot Bluestar Chemicals (Jiangxi) Co., Ltd. silicon dioxide production base will use monomethyl trichlorosilane, a by-product from the production of the Starfire Silicones Plant of Lanxing New Chemical Materials Co., Ltd. as its raw material, utilizing the world's advanced technologies. Produced nanoscale fumed silica products. At the same time, hydrogen chloride, a by-product produced during production, is returned to Blue Star Sparks Silicone Plant as a raw material for the synthesis of methyl chloride. The project will actively introduce and cultivate upstream and downstream enterprises through the rational extension of the silicon industry chain, so as to achieve a win-win situation of green development and cost savings for the company.
Ren Jianxin, chairman of China Bluestar (Group) Corporation and general manager of China National Chemical Corporation, said that this project is an important part of Bluestar Group's silicon monomer expansion and organic silicon downstream expansion implemented at Spark's organic silicon plant. With the growth of bluestar silicone business, Cabot Bluestar Chemicals (Jiangxi) Co., Ltd. can digest 500,000 tons of organosilicon by-product monomethyltrichlorosilane and other by-products of Spark Silicone Plant each year.
According to report, Jiangxi Xinghuo Silicone Factory is currently the largest organic silicon production enterprise in the country. Among the 15 enterprises led by Xinghuo Silicone Factory in Jiangxi Xinghuo Industrial Park, a close symbiotic relationship has been formed between enterprises. Integration, energy integration, and information integration have led to a variety of by-products discharged from organic silicon plants, forming multiple recycling resources. Lanxing Chemical New Materials Co., Ltd. and Cabot Bluestar Chemicals Co., Ltd. have cooperated to expand production capacity of fumed silica and used the by-products produced by both parties as their respective raw materials. Enterprises have truly formed an industrial sustainable development community, which has solved the problem. It is difficult to solve the problem of pollution in the production of silicones, but also produces a series of products with high added value such as nanoscale silica.
