Modeling And Control Simulation Of A 160 Thousands T/a MTBE Reactive Distillation Process

In recent years, catalytic distillation technology into MTBE (methyl tert-butyl ether) in industrial production has brought great economic benefits, which has been increasingly widespread concern, a large number of research results to promote the catalytic distillation technology.In this paper, engineering plant of the hot issues - MTBE Catalytic Distillation Process Simulation and Optimization Modeling and control of relevant technologies were studied.Based on pseudo-homogeneous assumption, established mechanism of the catalytic distillation process model,the reaction and separation process of decoupling, catalytic distillation process to derive the non-equilibrium stage dynamic model has been extended through the introduction of the separation efficiency function, the model variablesrational division, significantly increasing the efficiency of the model solution; the equation of dynamic model and control system combining the establishment of the catalytic distillation process control system of the auxiliary tool.Through the model calculation and analysis of the MTBE (methyl tert-butyl ether) synthesis of the dynamic characteristics of catalytic distillation process and found the process of serious non-linear and multi-time scale characteristics; designed and compared the two kinds of direct and indirect material balance indirectlyquality control program.The results showed that direct quality control program was able to take into product quality indicators.
