Important milestone achieved in Guangxi Hengyi’s 1.2 million-ton coal chemical project 2025-04-15 It was recently reported that the installation of 8 accident storage tanks in the packaging plant of Guangxi Hengyi New Materials Co., Ltd.’s integrated project capable of producing 1.2 million tons of caprolactam per year has been successfully completed, marking the final stage of the installation of large-scale equipment in this plant. It is reported that once the accident storage bin is put into use, it will be able to hold 1,500 cubic meters of substandard polyamide chips, reducing the plant’s emergency response time from 30 minutes to 8 minutes and thus providing strong support for safe production throughout the facility. The integrated hexamide-polyamide production facility with an annual output of 1.2 million tons, as well as the supporting projects at Guangxi Hengyi New Materials Co., Ltd., utilize two Aerospace Maiwei coal-based semi-waste boiler gasifiers to produce 100,000 m3/h of hydrogen and 200,000 tons per year of ammonia. Project Overview: The Guangxi Hengyi New Materials project, which involves the integrated production of 1.2 million tons of caprolactam and polyamides per year, has a total investment of around 22 billion yuan. Once operational, it will be able to produce 1.2 million tons of polyamide chips annually, generating annual sales revenue of about 20 billion yuan and annual tax revenues of 1.8 billion yuan. One phase of this investment amounts to around 12 billion yuan, covering an area of 1,700 mu. The construction includes facilities for producing 600,000 tons per year of **, 1.2 million tons per year of hydrogen peroxide, 200,000 tons per year of synthetic ammonia, 600,000 tons per year of caprolactam, as well as 600,000 tons per year of polyamide. The second phase of the project involves the construction of 1 set of hydrogen peroxide production facility with an annual capacity of 400,000 tons (based on 35% concentration), 2 sets of olefinic-based **production facilities with an annual capacity of 300,000 tons each, 2 sets of caprolactam production facilities with an annual capacity of 300,000 tons each, and 5 sets of polyamide polymerization facilities with an annual capacity of 120,000 tons each. The construction period for Phase II is 24 months, with commissioning expected in 2025.
