On July 20, the reporter learned from Lanzhou Science and Technology Association that the 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 delivered and put into use, which marks the first set/set in the country.
The Lumms process polypropylene polymerization reactor has been completed and realized localization, and at the same time, it has filled the gap in the design and manufacture of domestic polypropylene reaction equipment
.
The gas-phase polymerization reactor of the Lumms process in the CNOOC Ningbo Daxie project is the core equipment of the plant, and the equipment of the domestic in-service plant is imported
.
The CNOOC Daxie Petrochemical Polymerization Reactor Project is the first domestic polymerization reactor designed and manufactured using the Lumms process.
The Lumms process is a gas-phase polypropylene process.
It is necessary to connect two reactors in series or in parallel, which has great production flexibility, and can produce various polypropylene products such as homopolymer, random copolymer, terpolymer, and impact copolymer at the same time
.
The polymerization reactor is the key equipment in the Lumms process.
Previously, the patentee believed that there was no equipment manufacturer in China that could meet the processing requirements of this equipment.
The equipment that has been put into production uses imported equipment
.
As an excellent supplier of domestic polypropylene industry equipment, Tianhua Institute has profound technical reserves, design capabilities and manufacturing strength in equipment design and manufacturing.
Enterprise recognition
.
In order to ensure the smooth completion of the project, Tianhua Institute quickly established a project tackling team, formulated a detailed design plan, and put forward higher processing requirements in the key processing parts of the reactor based on the use requirements of CNOOC Daxie Petrochemical equipment, focusing on the design and manufacture of polymerization reactors Features and difficulties, using 3D laser scanning technology and large-scale CNC vertical lathe, the accuracy of the butterfly-shaped head of the reactor is controlled at 0.
025mm/m, and the error of the stirring template provided according to the patent requirements is 0.
5mm, which is far lower than the requirements of the patentee.
of 1mm
.
According to Zhang Wanyao, the leader of the domestic production project of the first/set of Lumms process polypropylene polymerization reactors in China, the director of the Chemical Engineering Research Department of Tianhua Institute and the deputy director of the Drying Institute, the completion of the CNOOC Daxie Petrochemical Polymerization Reactor Project not only It fills the gap in the domestic design and manufacture of polypropylene reaction equipment, and at the same time greatly improves the comprehensive research and design capabilities of Tianhua Institute and the core competitiveness of the enterprise
