The content involves the characteristics of the petrochemical industry and its technical requirements for process pumps; the application status of centrifugal pumps, including the results of localization, the gap with foreign products, and the energy utilization rate of pumps; the future market demand of the petrochemical industry, and Suggestions for use. >> Enter the International Pump Technology Summit Forum Key words: petrochemical industry centrifugal pump technology demand I. Introduction Second, the characteristics of the petrochemical industry and its demand for pumps The petrochemical industry is a process industry with the following main features: (1) The scale of the installation is large, and the economic scale of the production of continuous equipment is constantly expanding. At present, the mainstream scale of petroleum refineries has increased from 5 million to 8 million t/a in the 20th century to 10 million t/a; the mainstream scale of ethylene plants has reached 500,000 to 100,000 from 300,000 to 400,000 t/a. Ten thousand t/a threshold. Moreover, between the upstream and downstream, the device and the device are closely combined, the raw materials are mutually supplied, and the amount of heat (energy) is utilized for each other. Now, it is a very general level for the main unit to run continuously for 2 to 3 years. This fact not only poses some challenging issues for engineering design technology, but also raises higher requirements for the equipment manufacturing industry. (2) The process is complicated and the conditions are harsh. The modern petrochemical industry covers almost all chemical production processes ...

The petrochemical industry is one of the pillar industries of the national economy, and its contribution rate and pulling effect on the national economy are also among the forefront of the industry. Its development is not only related to the needs of the national economy and the people's livelihood, but also directly or indirectly to the development of other related industries, including the development of equipment manufacturing. The petrochemical industry is a process industry with continuous production and large scale. Not only is the process complex and demanding, but the equipment required is complex and numerous. Therefore, the petrochemical industry is not only a broad market for equipment manufacturing, but also a support object for equipment manufacturing. Therefore, it is of positive significance to explore the petrochemical industry's demand for technical equipment.
