The civil engineering work for Darat Banner Rongxin Chemical’s project to produce 800,000 tons of olefins per year is now complete. 2025-12-10 09:22 · Darat Release. As the winter cold intensifies, the enthusiasm for construction in the Darat Economic Development Zone in Ordos City remains undiminished. At the site of Inner Mongolia Rongxin Chemical Co., Ltd.’s project to produce 800,000 tons of olefins per year, construction activities are in full swing. Since the official commencement of work on April 1, 2025, the project team has focused on its goals and made every effort to move forward. After 240 days of intensive construction, the main civil engineering works have been completed successfully, and subsequent tasks such as equipment installation are being carried out steadily according to plan. With a total investment of 9.83 billion yuan and covering an area of 1,887 mu, this project is a key initiative for Dalaat Banner to promote the clean and efficient use of coal as well as to expand the coal-based industrial chain. The main construction components include an 800,000-ton/year methanol-to-olefins plant, a 400,000-ton/year polyethylene plant, a 400,000-ton/year polypropylene plant, a 15,000-ton/year 1-butene plant, along with supporting utility systems and auxiliary facilities. It is expected that the annual industrial output value will reach 6.67 billion yuan, while the industrial added value will be 2.079 billion yuan. Using methanol as the raw material, the project employs MTO technology to produce polymeric-grade ethylene and polymeric-grade propylene monomers, which are then used in polymerization processes to manufacture high-density polyethylene and high-performance polypropylene products. This approach significantly improves the conversion rate of raw materials, reduces the production cost per unit of product, further expands the industrial chain of the \"methanol-olefins-new materials\" cluster, and enhances market competitiveness.
