Recently, the supply contract for the first domestically produced ethylene plant 200,000-ton mixed extrusion granulation unit finally took off at Dalian Rubber Plastic Machinery Co., Ltd., and was officially started production and completed in March next year. Ethylene plant is a national major project of China's ethylene industry. Its key equipment, large-scale mixing extrusion granulator, is a technological “bottleneck†in China and an important project for localization of petrochemical equipment.
According to relevant sources, the large-scale mixed extrusion granulation unit is the most basic and important part of the entire production process from monomer to polymerization and extrusion granulation, and is an important post-processing equipment for large-scale ethylene plants. It is difficult to design and manufacture. At present, only a handful of companies in developed countries have mastered the technology of design, manufacture, installation and debugging, and control the market including China. The price is highly monopolized.
Since undertaking the task of localization of this major technology and equipment, the company has made effective preliminary preparations in more than a decade, and has successfully developed 70,000-ton and 100,000-ton large-scale mixing extrusion granulation units. The manufacturing technology of the main parts and components has been able to undertake the research and development of large-scale ethylene equipment in terms of technology, equipment, and practice. The 200,000-ton mixed extrusion granulation unit produced by Yanshan Petrochemical Company for Yanshan Petrochemical Company has been highly concerned by China Petroleum & Chemical Corporation. After more than one year of technical exchanges and business negotiations, the company reached an agreement. The use of Fang Yanshan Petrochemical and Beijing University of Chemical Technology and Tianhua Design Institute, both involved in the research of localization projects, jointly carried out research on localization equipment.
