en.Wedoany.com Reported - The 30% model review for the air separation unit of China's Xinjiang Dongming Plastics Co., Ltd.'s annual 8-million-ton coal-to-olefins project was successfully completed, marking an important phase achievement for the project.
The meeting focused on critical aspects of the detailed design, conducting comprehensive and in-depth technical reviews covering the general layout plan, process flow simulation, key equipment layout, and large equipment lifting plans to ensure the scientific feasibility of the design scheme. The project team from China Tianchen Engineering Co., Ltd. provided detailed explanations of the design scheme through 3D presentations, ensuring efficient and smooth technical communication. Based on practical production and operational needs, all participating parties formed multiple targeted optimization suggestions and reached a consensus on key technical schemes such as equipment layout and instrumentation & electrical systems, laying a solid foundation for the seamless connection between subsequent detailed design and construction.
Dongfang Hope Group Xinjiang Dongming Plastics Co., Ltd. 8-Million-Ton/Year Coal-to-Olefins Project
Project Name: Dongfang Hope Group Xinjiang Dongming Plastics Co., Ltd. Annual 8-Million-Ton Coal-to-Olefins Project
Construction Location: Modern Coal Chemical Industry Demonstration Zone, Zhundong Economic and Technological Development Zone, Xinjiang
Site Area: Approximately 186.4 m²
Project Scale: Using coal as raw material to produce methanol, which then goes through the MTO unit and olefin separation to produce polymer-grade ethylene and propylene. Part of the polymer-grade ethylene and propylene is sent to PP polymerization and PE polymerization to produce polyolefin products, and part is sent to the EPDM rubber unit to produce EPDM rubber. Supporting facilities include 2.2 million t/a methanol (pure equivalent) (including air separation, gasification, shift conversion, purification), 800,000 t/a methanol-to-olefins (including olefin separation), 400,000 t/a polypropylene, and 400,000 t/a polyethylene. In addition to the main products PP, PE, and EPDM rubber, the plant also co-produces sulfur, liquefied petroleum gas, heavy C4+, and other products.
Investment and Construction Plan: The total project investment is 18,967.44 million yuan (including foreign exchange of 378.35 million USD), of which the construction investment is 17,558.81 million yuan (including foreign exchange of 378.35 million USD), construction period loan interest is 1,025.91 million yuan, and working capital is 382.72 million yuan. The planned construction period is 24 months, with construction scheduled to start in April 2024 and be completed in April 2026.
Project Composition: The project mainly consists of main works, auxiliary works, utility works, storage & transportation works, environmental protection works, and reliant works. The main works primarily include: gasification unit, shift conversion unit, Rectisol unit, sulfur recovery unit, methanol synthesis unit, methanol-to-olefins unit, olefin separation unit, polyethylene unit, polypropylene unit, EPDM rubber unit, and water electrolysis unit. Auxiliary works include the air separation unit, raw coal pre-drying unit, flare system, fire protection, maintenance, office & laboratory, telecommunications, etc.
On June 18, 2025, the design and process package kick-off meeting for the 450,000 t/a polypropylene unit of the Xinjiang Dongming Plastics 8-Million-Ton Coal-to-Olefins Project was held at Ningbo Engineering Company.
