Safety first. Prevention first – let’s give praise and support to the achievements in China’s chemical engineering technology and equipment. **********************【A decade of rapid development in chemical engineering equipment】Continuous updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum). Recently, the deep etherification technology developed independently by Qilu Petrochemical was successfully tested in the 90,000-ton/year MTBE (methyl tert-butyl ether) production facility at Sinopec Dongxing Branch, marking the first successful industrial application of this technology in China. Currently, the isobutylene content in the butene fraction produced by domestic refining-type MTBE plants is relatively high, which fails to meet the requirements of subsequent 1-butene production facilities. In response to the needs of Sinopec Dongxing Branch, the research personnel at Qilu Petrochemical have continued to work on technical improvements; building on their existing MTBE technology, they developed a advanced etherification technique. After the facility was upgraded using this technique, it operated smoothly. After technical calibration, both the isobutylene content and conversion rate in the C4 hydrocarbons produced by the MTBE unit meet the specified requirements as well as those needed for production. The successful development and application of deep etherification technology have effectively reduced enterprises’ renovation costs and production expenses, laying the foundation for producing 1-butene from C4 hydrocarbons, and also providing experience for the upgrading of similar facilities.
