Recently, the installation for Guangxi Hengyi New Materials’ 1.2 million tons per year caprolactam–polyamide production integrated project was also successfully completed. Located in the Qinzhou Petrochemical Industrial Park in Guangxi, this facility is the largest industrial plant in the world to utilize gas-phase rearrangement technology, and it boasts significant advantages such as being green, low-carbon, clean, and efficient. Upon completion, the project will enable a production capacity of 1.2 million tons per year for high-end nylon materials, effectively filling a gap in key links of the industrial chain in South China. Its commissioning and operation will not only drive the regional petrochemical industry toward greater sophistication and higher quality, but also enable coordinated efforts to reduce pollution and carbon emissions through innovative processes. It holds strategic significance for helping Qinzhou develop a green chemical industry cluster and fostering high-quality economic development in the region. 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 per year, 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 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 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.
