Ten years of rapid development in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more interesting. With you here, HaiChuan becomes even better. [Ten years of progress in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhancing quality awareness to promote high-quality development. ----------------------------------------- On December 18, 2020, after 72 hours of stable operation, at 11:10 p.m. on December 17, with all test results for the final sample meeting the required standards, it was confirmed that the industrial-scale testing of PO/TBA (propylene oxide/tert-butanol) had been a complete success. 　　It is reported that, as the core unit of the carbon three and carbon four comprehensive utilization project, its process represents China’s first proprietary coproxygenation method for propylene oxide, developed through collaboration between Binhua Co., Ltd. and the Tsinghua University Institute of Industrial Research. This new technology possesses complete 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 last November, 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 unit via propane dehydrogenation, an 800,000-ton/year butane isomerization unit, a 300,000-ton/year propylene oxide production unit (with 780,000 tons/year of tert-butanol produced as a by-product), and a 150,000-ton/year synthetic ammonia plant, among others.
