With the rapid growth of China's economy, the demand for polypropylene has increased rapidly. In recent years, China's oil production capacity for polypropylene has increased significantly. In 2007, in order to further enhance the independent innovation capability and market competitiveness of polypropylene products, the company decided to build a polypropylene catalyst and pilot plant for process engineering by the Petrochemical Institute.
The total investment of the device is up to 99.98 million yuan. The main device consists of catalyst preparation, polymerization reaction, flash evaporation and drying. The designed capacity of the device is 75kgPP/h, and research work on homopolymerization of propylene, copolymerization of ethylene/propylene, and ethylene/propylene/butene-1 terpolymer can be carried out. According to experts, this device technology has reached the international advanced level.
The polypropylene catalyst and process engineering pilot plant project was approved by the feasibility study report in August 2007 and entered the device construction stage. Under the leadership and organization of the planning and planning department, science and technology management department, and refining and chemical branch companies of the Group Corporation, with the strong support and help of Lanzhou Petrochemical Company, the petrochemical institute is in a tight time, heavy tasks, no experience in the construction of similar devices, and boundary conditions. In the case of difficult to confirm, overcome difficulties, continue to strengthen the personnel training, system construction, safety management, and conditional guarantee of the pilot plant. After arduous efforts, ensure that the project quality and construction tasks are completed on schedule. The device was implemented on April 28, 2009.
Polypropylene catalyst and process engineering pilot plant has been successfully completed and put into operation, creating favorable conditions for the development of new catalysts in the field of synthetic resins, development of new products with high added-value synthetic resins, and optimization of production processes. It will surely improve the structure of synthetic resin products and improve products for CNPC. Market competitiveness plays an important role.
PetroChina's First Polypropylene Catalyst and Process Engineering Pilot Plant Feeding
On June 16, it was learned that the first set of polypropylene catalyst and process engineering pilot plant installed by China Petroleum and Petrochemical Research Institute had been successful in feeding materials and successfully delivered polypropylene products and achieved continuous and stable operation for 72 hours.
