Latest Progress on the Construction of a 600,000-ton Coal-to-Ethylene Glycol Plant in Xinjiang Author/Source: Huahua Network – Coal Chemical Industry Date: July 27, 2018 Clicks: 26 On July 24, the hoisting of the steam drum for Boiler No. 1 in the 4×340t/h boiler unit of the 600,000-ton ethylene glycol production line, which is part of the first phase of Xinjiang Tianye (Group) Co., Ltd.’s 1 million tons/year syngas-to-ethylene glycol project, was successfully completed. This achievement laid a solid foundation for the subsequent installation of the boiler’s water wall and heat exchange surfaces. It is understood that the drum of Boiler No. 1 weighs 74 tons, has a length of 16.358 meters, and is installed at a height of 45 meters. Moreover, its length exceeds the distance between the two sides of the steel structure, making horizontal lifting impossible. To ensure the safe and smooth progress of the lifting operations, the project’s preparatory team and the general contractor planned ahead and organized everything carefully, developing a thorough and scientific lifting plan. At the same time, safety training and technical briefings were provided to all technical personnel on site, to guarantee that all safeguard measures were in place and effective. Before lifting the steam drum of Boiler No. 1, the preparatory office carefully inspected the safety measures and mechanical equipment. Upon the issuance of the lifting command, the right side of the steam drum began to rise slowly; when the inclination reached 31°, the entire steam drum was lifted. Once the right end of the steam drum reached a height of 45 meters, it was leveled off and positioned correctly, achieving a successful one-time lift. During the lifting process, the crane operators had clear roles and worked in good coordination; the safety officers provided thorough supervision with great attention to detail. As a result, the entire lifting process was safe, orderly, and efficient. The first phase of Xinjiang Tianye (Group) Co., Ltd.’s project for producing ethylene glycol from syngas at a capacity of 1 million tons per year involves a facility for producing 600,000 tons of ethylene glycol per year. The total investment in this project amounts to 799,721.60 million yuan. The construction site is located in the Shihu Tan New Materials Industrial Park (147th Regiment) in Shihezi, Xinjiang. Construction began in August 2017, with completion and operation expected by October 2019. In October 2017, the project’s gasification technology sector entered into a contract with Shanxi Yangmei Chemical Machinery (Group) Co., Ltd. for four sets of 6.5MPa Jinhua furnaces model 3.0; the core process utilizes a patented technology for producing ethylene glycol from high-purity chemical synthesis gas. Xinjiang Tianye (Group) Co., Ltd. currently has a production capacity of 250,000 tons of ethylene glycol per year from synthetic gas; 50,000 tons from the first phase and 200,000 tons from the second phase, with these capacities being put into operation gradually. The second-phase project is located in the North Industrial Zone of Shihezi, Xinjiang, and involves the construction of facilities for producing 200,000 tons per year of ethylene glycol and 170,000 tons per year of BDO, utilizing the off-gases from calcium carbide furnaces in the Xinjiang Tianye Chemical Industry Park as raw materials for comprehensive utilization.
