Thread Content
China Gansu Net, July 21st, Lanzhou Daily reported on July 20th that the reporter learned from the Lanzhou Association for Science and Technology that a polypropylene polymerization reactor with an annual output of 300,000 tons designed and manufactured by Tianhua Chemical Machinery and Automation Research and Design Institute Co., Ltd. was recently delivered for use. This marks the completion and localization of the country's first Lummus process polypropylene polymerization reactor, and fills the gap in the design and manufacturing of domestic polypropylene reaction equipment. The CNOOC Daxie Petrochemical Polymerization Reactor Project is the first domestic polymerization reactor designed and manufactured using the Lummus process. The Lummus process is a gas-phase polypropylene process. Because it can flexibly arrange the reactor layout, two reactors can be connected in series or parallel as needed. It has great production flexibility and can produce homopolymers, random copolymers, terpolymers, impact copolymers and other polypropylene products at the same time. The polymerization reactor is a key equipment in the Lummus process. Previously, the patentee believed that there was no domestic equipment manufacturer that could meet the processing requirements of this equipment. Currently, all projects that have been put into production use imported equipment. As an excellent supplier of equipment for the domestic polypropylene industry, Tianhua Institute has profound technical reserves, design capabilities, and manufacturing capabilities in equipment design and manufacturing. It has provided excellent technical services to major domestic polypropylene production companies and has been recognized by domestic and foreign chemical companies. After many investigations, CNOOC Daxie Petrochemical experts believed that the comprehensive strength of Tianhua Institute fully met all the requirements for the design and manufacture of polymerization reactors, and finally decided that Tianhua Institute would complete the design and manufacture of the polymerization reactor for CNOOC's 300,000-ton polypropylene project.
