Happy New Year 2024 **********************【Ten Years of Rapid Development in Chemical Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** On January 30, 2024, Fuhai Group’s Hualian Petrochemical plant succeeded in producing qualified products from its 7,000 tons per year production facility for special engineering plastics, marking the successful industrialization of the first set of new material production equipment developed by Fuhai Group. Fuhai Group has established R&D centers in Shanghai and Dongying, bringing in experienced experts from the industry. Research on polysulfone resins began in 2019; the group has facilities such as a 150L pilot-scale research facility, a 3m3 scale-up research unit, and an industrial production facility with an annual capacity of 7,000 tons of polysulfone. Among these, the 7,000-ton/year polysulfone production facility is currently the largest of its kind in China. After five years of technical research and development, this project adopted a stepwise scaling approach. Through five years of efforts in technology development and engineering implementation, it progressed from pilot-scale research to pilot plant tests, carrying out stepwise scaling studies on reaction vessels with capacities ranging from 1L to 10L, 150L, and 3000L. The successful development and selection of key proprietary equipment helped overcome various technical challenges, including those related to suppressing cyclization side reactions, achieving high-purity separation and purification, effectively blocking terminal groups of polymer chains, and developing scalable production processes. The main performance indicators of the product, such as ash content, light transmittance, and haze, have reached international advanced levels. Fuhai polysulfone holds independent intellectual property rights in key processes such as purification and capping, having obtained **19 invention patents and filed 2 PCT international patents.
