Progress on the construction of the 800,000-ton-per-year coal-to-olefins plant at Wucuiwan in Zhundong, Xinjiang Shanneng Chemical Co., Ltd. Author/Source: Energy Knowledge Database Date: April 27, 2022 Clicks: 26 On April 24, 2022, Wang Xuyou, Party Secretary and Chairman of Xinjiang Shanneng Chemical Co., Ltd., and You Jiaqiang, Deputy Party Secretary, Director, and General Manager, visited the Wucuiwan facility in Zhundong for an inspection. After conducting on-site inspections of the No. 4 open-pit coal mine and the site designated for the 800,000-ton olefin project, Wang Xuyou and You Jiaqiang had thorough discussions with the designers from China Tianchen Engineering Co., Ltd. who were visiting, and offered constructive suggestions regarding the overall planning layout of the future factory and mine area, the allocation of functional zones, and the optimization of space utilization. The 800,000-ton-per-year coal-to-olefins project of Xinjiang Shanneng Chemical Co., Ltd. in Wucaiwan is located on the west side of Shenqi Road, at the entrance of Open-pit Mine No. 4 in the Huoshao Mountain Industrial Park, Wucaiwan Mining Area, Jundong Economic and Technological Development Zone, Xinjiang. The total investment is 19.8 billion yuan, with a total land area of 326 hectares. Tianchen Engineering Company is responsible for the overall design. This project uses coal from the Wucaiwan No. 4 open-pit mine as raw material, and produces MTO-grade methanol (an intermediate product) through coal gasification under pressure, shift reaction and heat recovery, low-temperature methanol washing, and methanol synthesis ； MTO-grade methanol is then processed through MTO and olefin separation to obtain polymer-grade ethylene and polymer-grade propylene monomers ； Polyethylene production through ethylene polymerization ； Propylene is polymerized to produce polypropylene products. The process technology planned for the main production units of this project is close to or reaches the current international advanced level. The main process units of this project include an air separation unit, a gasification unit, a purification unit, a methanol unit, a sulfur recovery unit, an MTO unit (including butane recycle), an olefin separation unit, a polyethylene unit, a polypropylene unit, etc. On March 17, the ceremony marking the resumption of work on major projects for the first quarter of 2022 in Changji Prefecture, Xinjiang, was held at the Zhundong Economic and Technological Development Zone in Xinjiang (hereinafter referred to as “Zhundong ETDZ”). The projects that are resuming operations include GCL’s polysilicon production facility with an annual output of 18,000 tons, Dongfang Hope’s polysilicon plant with an annual output of 90,000 tons, Dongfang Hope’s industrial silicon plant with an annual output of 230,000 tons, GCL’s industrial silicon plant with an annual output of 200,000 tons, Xinjiang Dongming Plastics’ coal-to-olefins facility with an annual output of 800,000 tons, and Yankuang’s coal-to-olefins plant with an annual output of 800,000 tons. On March 25, the Xinjiang Development and Reform Commission released the list of key projects for the autonomous region in 2022. Among the industrial projects, the reserved projects include: the Yankuang project in the Zhundong Development Zone with an annual production capacity of 800,000 tons of olefins, and the Dongming Plastics project in the same area with an annual production capacity of 800,000 tons of coal-based olefins. The project was approved in 2021. On March 21, 2022, the Land and Resources Bureau of Changji Prefecture approved Xinjiang Yankuang Qinen Coal Industry Co., Ltd. as the developer of Open-Pit Mine No. 4 in the Wucuiwan mining area of the Zhundong Development Zone, and designated the 800,000-ton/year coal-to-olefins project in Wucuiwan as the resource conversion project for Open-Pit Mine No. 4 in that area.
