Advanced Control of a Reactive Distillation Column

Simulated Heat Integration Study of Reactive Distillation Column for Ethanol Synthesis

Ethanol is largely used as a solvent in the synthesis of varnishes and perfumes. It is also used as a preservative for biological products, fuel, and gasoline additives. Anethanol-water mixture, normally obtained by fractional distillation</span...

Model Predictive Inferential Control of a Distillation Column

Typical production objectives in distillation process require the delivery of products whose compositions meet certain specifications. The distillation control system, therefore, must hold product compositions as near the set points as possible in faces of upset. In this project, inferential model predictive control, that utilizes an artificial neural network estimator and model predictive cont...

Design of Robust Low-order Controllers for Complex Processes: a Case Study on Reactive Distillation in a Medium-scale Pilot Plant

This paper deals with robust low-order controller design for a medium-scale pilot reactive distillation column. In the first step, a linear model of the column which is identified from experiments is used to compute the attainable control performance. In this step, actuator limitations and model uncertainty resulting from a priori knowledge as well as confidence intervals provided by the identi...

Optimal control of a reactive distillation column

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...
