Optimal Closed-loop Operation of Binary Batch Distillation Columns
نویسندگان
چکیده
The problem of designing an on-line optimizing robust output-feedback (OF) controller for binary batch distillation columns with temperature measurements is addressed. The combination of optimality, passivity and detectability notions leads to an estimator-based material balance controller that, for an ample range of load compositions maximizes the profit and yields the prespecified product purity. The scheme has: (i) a criterion to choose the sensor number and locations, (ii) an event controller that decides the total reflux, start-up and partial reflux withdrawal periods, and (iii) a tracking controller that steers the batch distillation column motion along an on-line optimized path. The approach is applied to a previously studied example. Copyright © 2005 IFAC.

Closed-loop Implementation of Optimal Trajectories in Batch Distillation
In order to implement a quasi-optimal trajectory derived from pinch theory [1,2], a temperature tracking control system composed by an open-loop reflux ratio control plus a closed-loop correction for disturbance rejection is proposed. To adjust the closed-loop controller we use the referential dynamic reaction of the process [3] and tuning rules [4] that, though they were originally developed f...

This work presents a robust method for the integrated design and operation of batch distillation whereby optimal column sizing, process flexibility and operating policies are obtained simultaneously based on the complex economic trade-offs between capital investment, production revenue and utility costs. The proposed stochastic framework, which utilises a genetic algorithm and a penalty functio...
متن کاملMultiple Steady States and Instability in Distillation. Implications for Operation and Control?
The fact that distillation columns, even in the ideal binary case, may display multiple steady states and unstable operating points has only recently been recognized. This article addresses some implications of these phenomena for the operation and control of distillation columns. Under manual operation, the multiplicity and instability will result in inability to reach separations correspondin...

متن کاملBatch Distillation: Simulation and Experimental Validation
Batch industries, specially the fine chemical industry, need rapid and robust mathematical models that can easily predict the degree of separation of mixtures like volatile organic compounds. Otherwise, in the study of on line production scheduling and planning of fine chemical plants, there is a lack of quick but reliable and more accurate than black box models in batch distillation. In this w...
