Capping of the powder storage framework for key units in Inner Mongolia Rongxin’s 800,000-ton olefin project

Thread Content

It was recently reported that the framing for the powder storage facility, a key supporting component of the Inner Mongolia Rongxin Chemical Project, has been successfully completed. The powder storage framework is the core storage facility of this chemical project, responsible for storing and transferring the powders required for production. The completion of its construction marks the official transition of the project from the \"infrastructure construction phase\" to the \"equipment installation and system commissioning phase\", laying an important foundation for subsequent construction work. It is understood that the powder storage frame is 23.6 m long, 10 m wide, and 15 m high; its construction was completed over 15 hours, with a total volume of concrete used amounting to 318 m³. Project Overview: The annual 800,000-ton olefin production project of Inner Mongolia Rongxin Chemical Co., Ltd. involves a total investment of 9.83 billion yuan and covers an area of 1,887 mu. It primarily includes 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 various supporting 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 used in polymerization to manufacture high-density polyethylene and high-performance polypropylene products. By-products such as 1-butene, isobutane, C5+, and MTBE are also generated. The project is scheduled to be completed and put into operation by 2026, with an expected annual industrial output value of 6.67 billion yuan and an industrial added value of 2.08 billion yuan. At the same time, it will effectively extend the local industrial chain for \"methanol-olefins-high-end new materials,\" helping to build a modern coal chemical industry cluster characterized by vertical integration and horizontal coordination. It will play a key role in serving as a model and driving industrial aggregation as well as improved quality and efficiency in Dalat Banner and the surrounding areas. According to Sinopec Guangzhou Engineering Company, the methanol-to-olefins process utilizes the DMTO-III technology, with the company undertaking the EPC general contracting. At present, project design and preliminary EPC planning have been fully launched.
