Xinjiang Tianye’s 600,000-ton ethylene glycol compressor completed successful trial run – Author/Source: Coal Chemistry Client, Date: 2019-07-23, Clicks: 62. On July 21, the two screw compressors in the air compression station of Xinjiang Tianye’s first-phase 600,000-ton/year ethylene glycol production project completed a successful trial run. As the first large-scale moving equipment to undergo testing for the project, its successful test run laid a solid foundation for the subsequent testing activities of the project. The instrument air produced by the screw air compressor will first be sent to the desalinated water unit, thereby creating favorable conditions for the individual testing of that unit. The successful commissioning of the screw air compressors in the air compression station of the air separation unit at the Xinjiang Tianye project marks the transition of the entire project from the construction phase to the commissioning phase, thus kicking off the commissioning work for this project. The 600,000 tons per year ethylene glycol production facility in Phase I of Xinjiang Tianye utilizes Tsinghua-type coal slurry gasification, shift reaction, methanol washing, and hydrogen/carbon monoxide separation to produce process gas, thereby meeting the requirements for the production of ethylene glycol and methanol. Ethylene glycol is synthesized and purified using carbonylation of DMO followed by distillation, as well as the hydrogenation of oxalate esters followed by distillation, while methanol is produced as a co-product at low pressure. The project was designed by Donghua Engineering Company. It is understood that the 600,000-ton ethylene glycol project of Tianye is the first project to be built in the Shihu Tan New Materials Industrial Park (North Area). It covers an area of 2,200 mu, with a total investment of around 8 billion yuan. Construction began in August 2017, and completion and operation are expected by the end of 2019. Upon completion, the project will generate economic benefits in the amount of 4.2 billion yuan per year, while also bringing about social benefits by creating 2,000 direct jobs. Additionally, the products produced by this project will serve as raw material inputs for the development of other projects in the park, such as a base for differentiated polyesters and specialty fibers, as well as a base for high-end olefins and engineering plastics.
