On December 20, 2020, the pipe welding volume of the entire plant of Hami Guanghui Ethylene Glycol Project exceeded 400,000 DIN (1.3 million DIN for the entire plant). This not only laid the foundation for the completion of the 600,000 DIN node by March 15, 2021 This laid a solid foundation and boosted confidence for the project to be launched before August 31, 2021.
The Hami Guanghui ethylene glycol project started pipeline installation in July this year. At the end of November, the hoisting of large equipment was completed.
The Hami Guanghui Ethylene Glycol Project purifies raw coal gas through conversion and gas purification and separation devices to obtain qualified carbon monoxide and hydrogen, and then produces ethylene glycol through the five-ring complex oxalate ester method. diol. It will be constructed in two phases, with the first and second phases each carrying 200,000 tons/year of ethylene glycol. EPC general contracting by Wuhuan Engineering Company.
Hami Guanghui Environmental Protection Technology Co., Ltd.’s comprehensive utilization of waste gas with an annual output of 400,000 tons of ethylene glycol project
On September 9, 2019, Guanghui Energy’s waste gas comprehensive utilization project with an annual output of 400,000 tons of ethylene glycol was fully constructed. The project relies on Xinjiang Guanghui Coal Clean Refining Co., Ltd., a subsidiary of Guanghui Energy Holdings. The 10 million tons/year coal graded upgrading and comprehensive utilization project uses by-product waste gas as raw material, and uses a series of technologies such as conversion, transformation, adsorption, and separation to produce high-end chemical ethylene glycol.
This project uses the “WHB synthesis gas to produce polyester-grade ethylene glycol” jointly developed by China Wuhuan and Huashuo Technology Co., Ltd. and Hebi BMW (Group) Co., Ltd. The third generation technology, through a series of processes such as conversion, transformation, low-temperature methanol washing, PSA adsorption and separation, extracts the high-value synthesis gas components H2 and CO from raw coal gas, and produces high-end products through carbonylation, hydrogenation, and refining technologies. Chemical products – polyester grade ethylene glycol.
Hami Guanghui Environmental Protection Technology Co., Ltd.’s waste gas comprehensive utilization project with an annual output of 400,000 tons of ethylene glycol is located in Naomao Lake Industrial Park, Yiwu County, Hami City, Xinjiang, with a total investment of 3.56 billion yuan. The project uses the third-generation technology of “WHB synthesis gas to polyester-grade ethylene glycol” jointly developed by China Wuhuan Huashuo Technology Co., Ltd. and Hebi BMW (Group) Co., Ltd., through conversion, transformation, low-temperature methanol washing, Through a series of processes such as PSA adsorption and separation, the high-value syngas components H2 and CO in raw coal gas are extracted, and high-end chemical products – polyester grade ethylene glycol are produced through carbonylation, hydrogenation, and refining technologies. Data shows that this PSA-CO device is also the largest pressure swing adsorption CO purification device in the world so far.
The Guanghui ethylene glycol project was built in two phases, the first phase is 200,000 tons, with a total investment of 1.87 billion yuan, and the second phase is 200,000 tons, with a total investment of 1.686 billion yuan.
Compared with coal-to-ethylene glycol projects, using raw coal gas to produce ethylene glycol can save more than 30% of project construction investment, significantly reduce the production cost of ethylene glycol products, and improve the overall profitability of the project. Not only It is in line with the new green development concept and plays a very positive role in promoting energy conservation and emission reduction and promoting ecological and environmental protection. </p
