Today, Inner Mongolia Hengyecheng Organic Silicon Co., Ltd. announced that its investment of 5.8 billion yuan to build a 600000 ton annual production of organic silicon monomer project has officially started production. This project adopts the world's first "low emission coupled production technology", reducing carbon emissions per unit product by 40% compared to traditional processes, marking a crucial step for China's organic silicon industry to transition from scale expansion to green and low-carbon.


Technological innovation: coupling processes to achieve near zero emissions of "three wastes"
The traditional production of organic silicon monomers relies on the direct process of "silicon powder+chloromethane", which produces 3.5 tons of waste hydrochloric acid and 0.8 tons of silicon containing waste residue per ton of product, with processing costs accounting for more than 15% of production costs. The Hengyecheng project utilizes a self-developed "chloromethane silicon powder methanol" coupled reaction system to recycle waste hydrochloric acid for methanol synthesis, converting silicon containing waste residue into white carbon black raw material, achieving "100% reuse of waste acid and 95% utilization rate of waste residue resources".


We have introduced an AI optimized control system to adjust the reaction temperature and pressure in real time, increasing the monomer yield from 88% to 92%. At the same time, the comprehensive energy consumption per ton of product has been reduced to 1.2 tons of standard coal, reaching the international advanced level. ”According to the Chief Engineer of Hengye Cheng, the photovoltaic power station and waste heat recovery device built to support the project can meet 30% of the electricity demand and reduce annual carbon dioxide emissions by 120000 tons.


Market Impact: Reshaping the Global Supply Chain Landscape
China is the world's largest producer of organosilicon, accounting for 65% of global production capacity in 2023, but high-end products such as high-purity methyl vinyl silicone rubber still rely on imports. After the Hengye Cheng project is put into operation, the annual production capacity of domestic organic silicon monomers will exceed 5 million tons, which can meet the downstream production demand of 100000 tons of silicone rubber and 80000 tons of silicone oil, and promote the extension of the industrial chain to high value-added links.


We have signed long-term supply agreements with international giants such as Dow Chemical and Evonik Industries, and the first batch of 200000 tons of monomers will be exported to Europe next month. "Hengye Cheng's marketing director revealed that the company plans to invest 2 billion yuan to build a deep processing base, focusing on the development of green products such as photovoltaic film and new energy vehicle seals. It is expected that the proportion of high-end products will increase from 30% to 60% within 3 years.


Industry evaluation: Green technology has become the core competitiveness
Experts from the China Fluorosilicon Organic Materials Industry Association pointed out that the Hengye Cheng project proves that competition in the organic silicon industry has shifted from scale to technology. Its coupled process reduces the cost by 800 yuan per ton, and if promoted nationwide, it can save more than 5 billion yuan in processing costs annually, while reducing the pressure of hazardous waste disposal. It is reported that the Ministry of Ecology and Environment has included this technology in the "National Key Promotion Low Carbon Technology Catalog" and plans to promote it in organic silicon parks across the country.
