Ethylene cracker simulation optimization software upgrade won the National Copyright Administration copyright certificate

The ethylene industrial cracker simulation and optimization software system (EPSOS) V2.0, developed by the Petrochemical Research Institute, Lanzhou Petrochemical Company and Tsinghua University for three years, successfully applied for the National Copyright Administration's copyright certificate.
The EPSOS 2.0 system is based on the successful industrial application of EPSOS 1.0 in 2008. It is a new generation of ethylene cracking furnace developed by the research and application of the 460,000-ton ethylene cracker simulation optimization application of Lanzhou Petrochemical, a subsidiary of China Petroleum Refinery and Chemical Corporation. Simulation and optimization software system. The verification test results of the full-cycle simulation accuracy of the 460,000-ton/year ethylene plant of Lanzhou Petrochemical Co., Ltd. show that the EPSOS 2.0 simulation accuracy meets the assessment index requirements of “the relative error of ethylene and propylene yield is less than 2% and 3%, respectively”. The industrial application test results of the full-cycle optimization program show that, compared to the optimization, the optimization scheme calculated by Lanzhou Petrochemicals using EPSOS 2.0 as a platform has increased the olefin yield of the naphtha cracking furnace by 0.6%, exceeding the assessment index of 0.5%. .
It is understood that the new version has a more user-friendly user interface, a more concise, visualized operating system, a richer basic database, more accurate simulation accuracy, more sophisticated optimization capabilities and a faster calculation process. At present, the software has obtained the software copyright certificate issued by the National Copyright Administration, which can be popularized and applied in large-scale ethylene installations.
