On March 1, excavation work began at the hexane mother liquor tank area of Inner Mongolia Rongxin HDPE project, marking the official start of the civil engineering works for this project. The 800,000 tons per year methanol-to-olefins project of Inner Mongolia Rongxin Chemical Co., Ltd. is located in the Saniangliang Industrial Park in Dalat Banner, Inner Mongolia Autonomous Region. Using methanol as raw material, it employs MTO technology to produce polymeric-grade ethylene and propylene, which are then polymerized to yield high-density polyethylene, polypropylene products, and other by-products. The facility consists of a methanol-to-olefins unit, a polyethylene unit, a polypropylene unit, along with supporting utility systems and auxiliary facilities, and it is integrated seamlessly with Rongxin Chemical’s existing systems and installations. With a total investment of 9.83 billion yuan, the project mainly involves the construction of 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, as well as associated auxiliary facilities. The project uses methanol as a raw material and employs MTO technology to produce polymeric-grade ethylene and polymeric-grade propylene monomers, which are then polymerized to yield high-density polyethylene and high-performance polypropylene products. Additionally, by-products such as 1-butene, isobutane, C5+, and MTBE are generated. Completion and operation of the project are expected by 2026. It is reported that Rongxin Chemical’s polypropylene (PP) and high-density polyethylene (HDPE) production facilities will utilize LyondellBasell’s Spheripol and Hostalen ACP process technologies.
