Simulation Study On Energy Saving And Consumption Reduction Of Acrylonitrile Production Equipment

This paper takes acrylonitrile production plant in Jilin Chemical Industrial Co.,Ltd.as research objects.The process parameters of the production plant can be optimized.First,the process units were simulated by well know chemical process simulation software PRO/?.In the process of simulation,quenching section,absorb section,recover section,refine section and four-effect evaporation section were simulated,respectively.The PRO ? simulation programs were improved by comparing with the actual production data,while the improved simulation programs were used to analyze process parameters.The main process parameters were optimized by the PRO/? simulation model aiming at saving energy and reducing consumption.The process parameters conclude the feed rate of top of quench tower,the amount of sulfuric acid,the tower pressure and withdraw rate of absorber,the amount of solvent water and temperature of quantizer in recover column,the tower pressure of finished tower and duty of stripping tower.If the optimized process parameters can be implemented,the acrylonitrile production plant will increase the efficiency of 1510,000 yuan.This study has the significance of direction and guidance for the plant's actual production operation.
