The future development direction of China's petrochemical equipment: First, large-scale equipment, and second, multi-functionalization of technical indicators, and third, production equipment operation is more safe and reliable. Therefore, China's chemical equipment industry should establish a modern industrial design system, promote product innovation and optimization design technology and computer simulation technology, and promote the upgrading of petrochemical equipment products. In the "Technical Guidelines for the Revitalization and Support of the Petroleum and Chemical Industry", the main contents of the supporting technology in the field of chemical equipment are: Relying on major petrochemical engineering projects, with 10 million tons of oil refining, million tons of ethylene, and fine benzene Large-scale cracking furnaces, large-scale coal gasifiers, large-capacity compressors, key pump valves, reaction heat exchangers, large-scale extrusion granulators, and large-scale air separation are the focus of formic acid, large chemical fertilizers, and large-scale coal chemical plants. Equipment, cryogenic pumps and other key equipment to promote the autonomy of petrochemical equipment. At the same time, new types of energy-saving, miniaturized, multi-functional new equipment such as baffle-type high-gravity rotary bed, new heat exchangers, and new-type filters have been developed.
The large-scale built-in heat-exchange fluidization dryer is a promotion project in the industry revitalization support technology catalog. Oscillating flow heat pipe as a new type of high-efficiency heat transfer element has wide application prospects in the field of industrial waste heat recovery, high-performance heat exchangers in industrial processes, heat supply and heat recovery of drying equipment, and utilization of solar energy. In this project, the oscillating heat pipe heat exchanger is introduced into the fluidized drying system, and the waste heat is first recovered before the high-temperature exhaust gas is evacuated, preheating the air used in the drying system to achieve an energy-saving effect. Among them, the exhaust heat recovery rate is not less than 10%, and the fluidization drying device thermal efficiency is higher than 80%. At present, the device has been vigorously promoted in the soda ash and refined salt industry, which has promoted technological advancement in these industries.
The large-sized extrusion granulation unit is a development project in the Industrial Revitalization Support Technology Catalog. Ethylene is the most widely used basic raw material of organic chemicals. The large-size extrusion granulation unit is the most basic and important part of the whole production process from monomer to polymerization and extrusion and granulation, and is an important part of post-processing in large-scale ethylene plants. The equipment is also the final “fortress†for the localization of key equipment for the one million tons ethylene project in the petrochemical industry in China. The main research contents of the project include: high power, high speed, high torque, special double shaft reducer, high precision slender mandrel, high precision screw, kneading elements, barrels and other key parts, high pressure and high temperature resistant sealing device ,Throttle driving valve, network changing device, melting gear pump, template and underwater pelletizing device, high reliability electrical control system, processing technology research and process equipment. The project has determined that Yanshan Petrochemical's ethylene renovation project will be relied on. Six units including Dalian Rubber and Plastic Machinery Co., Ltd., Beijing University of Chemical Technology and Yanshan Petrochemical Co. At present, the first 200,000-ton/year polypropylene large extrusion granulation unit has been accepted for delivery.
Chemical Equipment: Integrated Localization of Innovation
Since the beginning of the 21st century, China's petrochemical industry has maintained rapid growth and its industrial scale has continued to expand. Although China’s petrochemical equipment manufacturing industry has introduced equipment mapping, piracy, and digestion and absorption, it has developed a number of large-scale petrochemical production equipment of international advanced level, and has built a number of localized devices with modern technology, but high-end Products still rely on imports, poor system integration capabilities, and weak technological innovation capabilities, and the product structure needs to be adjusted.
