Role of Multiplicity in Control System Design for a Methyl Acetate Reactive Distillation Column
The impact of steady-state multiplicities on the control of a methyl acetate reactive distillation (RD) column is studied. It is shown that input multiplicity, where multiple input values give the same output, can lead to “wrong” control action, leading to poor robustness. A new metric, rangeability, is defined to quantify the severity of input multiplicity in a steady-state input-output (IO) r...
متن کاملMultistep model predictive control of ethyl acetate reactive distillation column
An unconstrained model predictive control (MPC) strategy is presented for single input-single output (SISO) control of a reactive distillation column. The predictive model of the MPC is based on the autoregressive moving average (ARX) model structure, whose parameters are updated on-line using the process measurement information. The design and performance of the control strategy is evaluated b...
متن کاملReactive distillation for methyl acetate production
We describe a hierarchy of methods, models, and calculation techniques that support the design of reactive distillation columns. The models require increasingly sophisticated data needs as the hierarchy is implemented. The approach is illustrated for the production of methyl acetate because of its commercial importance, and because of the availability of adequate published data for comparison. ...
متن کاملComparative control study of ideal and methyl acetate reactive distillation
The control of an ideal reactive distillation column is compared with that of a similar, but somewhat di2erent, real chemical system, the production of methyl acetate. Similarities and di2erences are observed. Three control structures are evaluated for both systems. A control structure with one internal composition controller and one temperature controller provides e2ective control of both syst...
متن کاملAdvanced Control of a Reactive Distillation Column
The paper presents a detailed analysis of the dynamic behavior of a reactive distillation column. A control relevant dynamic model is derived using firstprinciples modeling and it is used to study the dynamic behavior of the process at high and low purity operating regimes. The results are used to analyze the performance of linear and nonlinear model predictive control in comparison to coupled ...
