Researchers of the Yangzi Petrochemical Research Institute cooperated with East China University of Science and Technology and the company's olefin plant to use advanced models to perform process optimization calculations, laying a solid foundation for the research and development of ethylene online optimization technology. After nearly two years of hard work, the project has made great progress. Once the project is applied, it can optimize the operation of the ethylene plant online, drastically reduce production costs, provide the most direct help for enterprises to reduce costs and increase efficiency, and enhance the company's ethylene production technology level and enhance its international competitiveness.
The cracking furnace is the leading equipment and key equipment for ethylene production plants. It is estimated that the economic benefits obtained by adopting advanced technology control will account for about 40% of the benefits of the entire ethylene plant. Many foreign companies have had successful application experience and developed commercial software for crack depth models. The Yangtze Research Institute had earlier introduced similar software and successfully applied the process optimization of the ethylene plant in Yangzi. However, due to the rapid changes in cracking raw materials, the software can only be optimized offline, which restricts the optimization efficiency. In response to this situation, Yangzi Petrochemical started the research on the research and development of on-line model and real-time optimization technology of ethylene cracking furnace in 2006. The project was conducted by East China University of Science and Technology and Yangzi Olefins Factory in cooperation with the Institute. To study the online model of the cracking furnace and to develop a real-time cracking depth optimization technique. The Yangtze Research Institute is responsible for providing pyrolysis oil analysis data and cracker model data to establish a core technical foundation for expert reasoning models.
After nearly two years of hard work, the Yangtze Research Institute has accumulated a large amount of analytical data of naphtha cracking raw materials, and established a cracking raw material database, collected the corresponding cracking furnace process conditions and sampling and analysis of the cracked gas, obtained a full The pyrolysis furnace operation information, using SPYRO software for simulation calculation to obtain a large number of cracker process optimization data, laid a solid foundation for the development of cracking furnace online model and real-time optimization technology.
