On November 6, the concrete pouring for the top slab of the combined compressor foundation for the second-phase 33,000 Nm³/h air separation project at Guangxi Hengyi New Materials Co., Ltd., which was undertaken by the 206 Project Department of the Second Branch and the Air Separation Engineering Branch of Zhejiang Industrial Equipment Installation Group Co., Ltd., was successfully completed. This breakthrough at this critical stage marks significant progress in the foundational construction of the project’s key equipment, laying a solid foundation for the subsequent installation of larger equipment and the advancement of the entire project. It is understood that once completed, this air separation plant will supply stable and high-purity industrial gases such as oxygen and nitrogen to Guangxi Hengyi’s new materials production base, providing strong support for the expansion of its industrial chain and the upgrading of its production capacity. This is of great significance for promoting the high-quality development of the regional new materials industry. According to Guangxi Hengyi New Materials, the first-phase construction mainly includes production facilities such as 2×300,000 tons per year of cyclohexanone, 2×400,000 tons per year of hydrogen peroxide, 300,000 tons per year of synthetic ammonia, 100,000 standard cubic meters per hour of hydrogen production, 2×300,000 tons per year of caprolactam, and 2×300,000 tons per year of polyamide polymerization. The coal-to-hydrogen ammonia synthesis complex uses a Shaohang Maiwei pulverized coal semi-waste boiler gasifier. Hydrogen peroxide is produced using the fluidized bed process technology independently developed by Hengyi Research Institute. Polyamide is the Gemma process package from Germany. 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 cyclohexanone, 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 will mainly involve 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 cyclohexanone production facilities using the olefin process 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.
