On March 23, Guanghui Energy Co., Ltd. replied to investors: As of December 31, 2020, the project of comprehensive utilization of waste gas with an annual output of 40,000 tons of ethylene glycol has completed a total investment of 3.8012116 million yuan. The cumulative payment was RMB 1,840,534,900. The capital investment in the project is all the company’s own or self-raised funds. As of the announcement date, its own funds and two phases of project loans provided by banks have been implemented. The funds are sufficient to meet the overall construction of the project, and the construction progress is progressing normally as planned.
Project Overview
On September 9, 2019, Guanghui Energy Gas Comprehensive Utilization Year The project to produce 400,000 tons of ethylene glycol has been fully started. The project relies on the by-product shortage of the 10 million tons/year coal graded upgrading and comprehensive utilization project invested and constructed by Xinjiang Guanghui Coal Clean Refining Co., Ltd., a subsidiary of Guanghui Energy. Coal gas is used as raw material, and a series of technologies such as conversion, transformation, adsorption, and separation are used to produce high-end chemical ethylene glycol.
This project uses the “WHB syngas production and polymerization” jointly developed by China Wuhuan and Huashuo Technology Co., Ltd. and Hebi BMW (Group) Co., Ltd. The third generation technology of “Ester Grade Ethylene Glycol”, through a series of processes such as conversion, transformation, low-temperature methanol washing, PSA adsorption and separation, etc., extracts the high-value synthesis gas components H2 and CO in raw coal gas, and through carbonylation, addition Hydrogen and refining technology produce high-end 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.
The latest domestic ethylene glycol plant trends
Puyang Yongjin Chemical Co., Ltd., 200,000 tons The ethylene glycol unit will be shut down for maintenance on March 9, and the maintenance is expected to take 20 days.
Inner Mongolia Ordos Xinhang Energy Co., Ltd., a 360,000-ton ethylene glycol unit, started to replace catalysts on three wire wheels on the evening of March 9, and kept two trains open and shut down. A set of conditions lasts about a month.
Fushun Petrochemical’s 40,000-ton ethylene glycol unit plans to start shutting down for maintenance on April 16, which is expected to last about two months.
The 300,000-ton ethylene glycol plant in Anhui Haoyuan is under construction as planned. It is currently in the equipment installation stage and is progressing smoothly. It is expected to be delivered at the end of June and products will be released in early July. </p
