Application Of Chemical Simulation Technology In Energy Saving And Optimization Of Phenol Acetone Plant

This paper introduces the production technology and development direction of phenol and acetone,and optimized the UOP method phenol acetone device with Aspen Plus software as the tool.The oxidation unit was optimized at first,we analyzed the oxidation reaction principle,established the simplified reaction kinetic model,and using RTSCR reactor to simulated the cumene oxidation process,we improved the selectivity of the reaction by optimized the volume of the reactor.Then we conducted the steady state simulation of the concentration unit according to the actual production data and equipment parameters,and analyzed the problems existing in the device.And by increasing the flash tower and replacement preheaterwe,we solve the production stability problem in concentration unit,improve the production capacity and production safety.Final we optimized the alpha-methylstyrene unit,we analysis the reason of alpha-methylstyrene substandard product quality and high energy consumption in the device,and redesigned the separation process,accounted the thermodynamics and hydraulics date in the distillation column.The simulation results show that the optimized of alpha-methylstyrene product achieve the market indicators,through the optimization of alpha-methylstyrene unit,we can save more than 5.6 minllion yuan a year.The application results of Plus Aspen software in this paper show that the computer simulation technique can be used to simulate the steady state production process,improve the current process and eliminate the bottle neck.Compared with the traditional experimental data,it saves a lot of resources and time,and it is the trend of the development of information and intelligence.
