On June 11, a ceremony to sign the general contract for the design, procurement, and construction of the project to produce 500,000 tons per year of polydimethyl ether (with an initial production capacity of 100,000 tons per year) at Yanzhou Coal Industry Yulin Energy Chemical Co., Ltd., was held in the Hualu Building. Leaders such as Wang Hai, Secretary of the Party Committee and Chairman of the company, Kang Jianbin, Deputy Secretary of the Party Committee and General Manager, Jin Fangyu, Secretary of the Party Committee, Chairman, and General Manager of Yanzhou Coal Industry Yulin Energy Chemical Co., Ltd., and Cao Jinseng, Chief Engineer, attended the meeting. Yanzhou Coal Industry Yulin Energy Chemical is an important strategic partner of Hualu Technology, and the two parties have maintained a good cooperative relationship for a long time. This project collaboration represents full recognition by Yanzhou Coal Industry Yulin Energy Chemical of the efforts that Hualu Technology has made over the years on projects for Yankuang Group. Hualu will provide high-quality engineering services in return for the trust and support given by Yankuang Group and Yulin Energy Chemical, thereby laying the foundation for more in-depth and extensive cooperation between the two parties. Jin Fangyu expressed his gratitude to Hualu Technology for its years of support to Yankuang Group and Yulin Energy Chemicals. Yanzhou Coal Industry Yulin Energy Chemicals shares a deep friendship with Hualu. The DMMn project carried out through this cooperation poses new tests and challenges for both parties. It is hoped that Hualu Technology will organize the work carefully and carry out it in a scientific manner, making full use of the company’s advantageous resources to ensure the successful completion of the project and its timely commissioning. Under the witnesship of leaders from all parties, Wang Hai and Jin Fangyu signed the general contract for project management on behalf of their respective sides. The 500,000 tons per year DMMn (polymethoxydimethyl ether) project of Yanzhou Coal Industry Yulin Energy Chemical Co., Ltd. is scheduled to require a total investment of 4.596 billion yuan. In this project, coal is used to produce polymethoxydimethyl ether through methanol synthesis; the main technologies employed include coal gasification, raw gas purification, methanol synthesis, methanol distillation, sulfur recovery, and DMMn production. Its main products are methanol and DMMn (full name polymethoxydimethyl ether, an ideal new component for diesel blending, and which can also be used directly as a non-aromatic, environmentally friendly solvent) ； By-products include sulfur, liquid oxygen, liquid argon, etc. The project uses one oxygen generation unit with a capacity of 92,000 Nm3/h ； Gasification is carried out using the multi-nozzle (opposed-type) water-coal slurry gasification technology owned by Yankuang Group, with a total effective gas production capacity of 240,800 Nm3/h. Three gasifiers with a capacity of 2,000 t/d each are installed (2 with quenching systems and 1 with a semi-waste boiler), operating in a 2-on-1-backup configuration ； The purification unit uses the Dalian University of Technology low-temperature methanol washing process ； Methanol synthesis utilizes technology from East China University of Science and Technology ； Distillation utilizes the Tianjin Beiyang five-column methanol distillation technology, with a processing capacity of 5,000 tons per day in total. The DMMn plant utilizes Metada’s DMMn technology, and its construction is carried out in two stages: first, a plant with an annual production capacity of 100,000 tons is built, followed by the construction of a plant with a capacity of 400,000 tons.
