Latest Progress on the Construction of Xinjiang Tianye’s 600,000-ton Coal-to-Ethylene Glycol Project Author/Source: Huahua Network – Coal Chemicals Date: 2018-08-14 Clicks: 4 At 11:20 a.m. on August 6, lifting operations began on the first buffer tank in the DMO unit of Xinjiang Tianye (Group) Co., Ltd.’s first-phase project for producing ethylene glycol from syngas, with an annual capacity of 1 million tons; this marked the official start of equipment installation in that unit. The DMO buffer tank is 9.518 meters long, weighs 6.4 tons, and has a diameter of approximately 2.1 meters; it is fixed to the cylindrical concrete foundation mainly through 12 embedded bolts. To advance the construction progress of the DMO section efficiently, the project’s technical team formulated plans scientifically, organized construction carefully, and strictly monitored key project milestones to ensure that all tasks were carried out in a coordinated manner. To date, the DMO section has seen busy activity with civil construction and equipment installation, with all tasks being carried out in line with the plan. At 17:08 on July 31, the first steel structural column of the DMO synthesis system for Tianye’s 600,000-ton coal-based ethylene glycol project was lifted into place and aligned, marking the official entry of this system’s construction into the steel structure installation phase. It is understood that the DMO synthesis system for Tianye’s 600,000-ton coal-based ethylene glycol project covers an area of 900 square meters; its upper structure (5 floors) consists of steel frame platforms. It is estimated that around 5,250 tons of steel structures will be installed, with a construction period of 60 days. As planned, the DMO synthesis system will have its steel structure installation completed by the end of September 2018; thereafter, work will proceed on the installation of equipment and process pipelines as well as commissioning. It is expected that by September 2019, the entire system will have undergone individual unit tests and be ready for operation. 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 makes use of a patented technology for producing ethylene glycol from high-pressure 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.
