Wuhai Zhonglian Chemical Co., Ltd. plans to build a trichlorosilane (TCS) new material integrated cycle project, which was filed on May 15. With a total investment of RMB 1.5 billion, the project is located at Xiwang Chemical Park, Hainan District, Wuhai City, Inner Mongolia. The plant is projected to be completed in September 2024. In the Phase I of the whole project, the company will build an 100 kt/a TCS unit, a matching 150 kt/a ion membrane caustic soda unit to provide hydrogen chloride as the raw material for the production of TCS, meanwhile the TCS plant is to annually produce 17.6 kt of byproduct STC. In addition, the waste salt in surrounding areas is collected as the upstream raw materials for caustic soda. In the Phase II, the company will build an additional 150 kt/a ion membrane caustic soda device, collecting partial waste salt as raw materials like the Phase I.
