On November 13, the lifting of the upper half of the light tower C14304 of the ethylene glycol synthesis unit of the Hami Guanghui ethylene glycol project, which was general contracted by China National Chemical Wuhuan Company and constructed by China National Chemical 14th Company, was completed. So far, the upper and lower sections of the heaviest tower of the project’s synthesis device have been successfully “integrated”.
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, Yiwu County, Hami, Xinjiang The town industrial park is the first domestic project to use raw coal gas to produce ethylene glycol. After completion, the project can directly reduce CO2 emissions by more than 625,000 tons per year, and indirectly reduce CO2 emissions by about 1.7 million tons. It is a typical environmental protection, energy saving, and comprehensive utilization project of industrial exhaust gas. With the equipment hoisted in place, the hoisting work of large-scale equipment for the Hami Guanghui ethylene glycol project has entered the final stage.
Hami Guanghui Environmental Protection Technology Co., Ltd. comprehensive utilization of waste gas with an annual output of 400,000 tons of ethylene glycol project
September 9, 2019, Guanghui The energy shortage gas comprehensive utilization project with an annual output of 400,000 tons of ethylene glycol is fully under construction. The project relies on the 10 million tons/year coal classification and quality improvement invested by Xinjiang Guanghui Coal Clean Refining Co., Ltd., a subsidiary of Guanghui Energy Holdings. Comprehensive utilization of the project’s by-product waste gas as raw material, using a series of technologies such as transformation, 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
