【Ten Years of Great Progress in Chemical Technology】China’s First Self-Developed Coproxygenation Process Epichlorohydrin Plant from 195 to 2020

Thread Content

Ten years of remarkable progress in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Be careful with fire as the heat increases in July. ------------------------------------------- After 72 hours of stable operation, at 23:10 on December 17, 2020, the completion of analysis on the last sample, with all results meeting the required standards, marked the successful conclusion of the industrialization trial of PO/TBA by BinHua Group. This is the first PO/TBA technology in China with independent intellectual property rights, and it represents a milestone in breaking the technological monopoly held by international chemical giants. As the core unit of the comprehensive utilization project for C3 and C4 compounds, its process represents China’s first proprietary propylene oxide production technology based on the co-oxidation method, developed through collaboration between Binhua Co., Ltd. and the Tsinghua University Institute of Industrial Research. This new technology possesses full independent intellectual property rights; it not only breaks the technological monopoly held by international chemical giants but also increases profit margins by at least 10%. This industrialization test is of milestone significance, laying the foundation for the comprehensive advancement of the Binhua Beihai project. As early as November 2019, Shandong Binhua New Materials, a joint venture established by Binhua Co., Ltd. and Tsinghua University, invested around 12.9 billion yuan in building a new project for the comprehensive utilization of carbon tiers 3 and 4. The project mainly includes a 600,000-ton/year propylene production facility via propane dehydrogenation, an 800,000-ton/year butane isomerization facility, a 300,000-ton/year propylene oxide facility (with 780,000 tons/year of tert-butanol produced as a by-product), and a 150,000-ton/year synthetic ammonia facility, among others.
