Progress on the Construction of the 500,000 tons/year Polydimethyl methoxide Project at Yanzhou Coal Yulin Energy Chemicals. Author/Source: Sinochem 13th Construction Company. Date: October 30, 2019. Clicks: 3. In the early hours of October 28, the methanol distillation unit and intermediate tank area of the 500,000 tons/year polydimethyl methoxide project operated by Yanzhou Coal Yulin Energy Chemicals Co., Ltd., which was constructed by the second branch of Sinochem 13th Construction Company, successfully received methanol within the time frame set by the project owner. The second phase of the Yulin Methanol Plant owned by Yankuang Group involves the construction of a facility capable of producing 500,000 tons per year of coal-based polymethoxymethane (DMMn). The investment in this project exceeds 5 billion yuan, and the site covers an area of 55.3 hectares. It is currently the largest DMMn production project under construction in China. The project is carried out in two stages: first, a facility with an annual production capacity of 100,000 tons of DMMn will be built, and once it is operating stably, a facility with an annual capacity of 400,000 tons will be constructed. A total of 3 multi-nozzle gasifiers from East China University of Science and Technology were designed for this project: 2 are quenching-type gasifiers, and 1 is a semi-waste-heat boiler type gasifier. The project involves the production of polydimethyl methoxide from coal through methanol, with the DMMn facility utilizing patented technology from Qingdao Maiteda New Materials Co., Ltd. The Yulin Methanol Plant is the first coal chemical enterprise established by Yankuang Group in Yulin, Shaanxi. It was registered on February 24, 2004, with a registered capital of 1.4 billion yuan. Phase 1 of the project is a coal-to-methanol facility with an annual production capacity of 600,000 tons. It required an investment of 3.8 billion yuan and covered an area of 69.8 hectares. Construction began in 2006 and the facility came online in 2008; it was the largest coal-to-methanol plant of its kind in China at that time. It adopted four world-class process technologies from GE Energy of the United States, including the Texaco gasification technology.
