The framework of Tower No. 3 in the second circulating water system of Shaanxi Coal Group Yulin Chemical’s 1.8 million tons per year ethylene glycol production project was successfully completed. Author/Source: Refining and Petrochemical News. Date: December 4, 2020. Clicks: 6. On November 30, the framework of Tower No. 3 in the second circulating water system of that project was completed. The No. 3 cooling tower in the second circulating water plant is 88 m long, 25.8 m wide, and 23.41 m high, with a water treatment capacity of 60,000 m3 per hour. The main quantities for Tower 3# include 6,669.23 m3 of concrete, 1,307 tons of steel reinforcement, and 18,285㎡ of scaffolding installation. It is reported that the project is located in the Yushen Industrial Zone of Yulin City, Shaanxi Province, and it is currently the largest recirculating water facility of its kind in China. Yulin Chemical is carrying out the construction of a demonstration project for the production of new chemical materials through the differentiated utilization of coal in the Qingshui Industrial Park of the Yushen Industrial Zone. As the largest coal chemical project under construction globally at present, this project covers an area of approximately 13 square kilometers. The total planned investment is 126.2 billion yuan, and it will be able to process over 24 million tons of coal per year. The project is constructed in two phases and four stages, comprising a total of 27 process units along with associated utility systems. These mainly include the medium- and low-temperature pyrolysis of 15 million tons of coal, the production of 5.6 million tons of methanol, 1.8 million tons of ethylene glycol, 2 million tons of MTO, as well as downstream products derived from these intermediates. The first phase of the project requires an investment of around 70 billion yuan; it will involve the construction of facilities for producing 1.8 million tons per year of ethylene glycol, 5.6 million tons per year of methanol, and 2 million tons per year of olefins, as well as a large amount of fine chemical products derived from these olefins. The 1.8 million tons per year ethylene glycol project is the first phase of this initiative, and it is also the largest coal-based ethylene glycol project under construction worldwide. The estimated investment for this project is 26.5 billion yuan. The project utilizes Collin’s patented dry powder gasification technology and Japan’s patented technology for producing ethylene glycol from syngas. Shanxi Coal Group Yulin Chemical Co., Ltd. and Nippon Kako Kagaku Co., Ltd. jointly invested in establishing Shanxi Coal Group Yulin Chemical Yugao Chemical Co., Ltd. to build and operate facilities for the production of oxalate esters as well as for the hydrogenation of oxalate esters to produce ethylene glycol. One of the overall objectives set for the project construction is to achieve mechanical completion by June 30, 2021, for the first phase of Project Phase 1, which involves an ethylene glycol production facility with a capacity of 1.8 million tons per year, as well as the first phase of Project Phase 2, which includes a coal pyrolysis facility with a capacity of 1.2 million tons per year and an industrial demonstration unit for the deep processing of coal tar with a capacity of 500,000 tons per year.
