State Estimator Design for Multicomponent Batch Distillation Columns

State Estimator Design for Multicomponent Batch Distillation Columns

I n the control of batch distillation columns, one of the problems is the difficulty in monitoring the compositions. This problem can be handled by estimating the compositions from readily available online temperature measurements using a state estimator. In this study, a state estimator that infers the product composition in a multicomponent batch distillation column (MBDC) from the temperatur...

Multicomponent batch distillation column design

A simple design method for multicomponent distillation columns

Multicomponent-distillation calculation methods are classified as rating or design methods. A few rating methods are widely used but none of the design methods has found general acceptance. Recently, a few design methods have been proposed using the stage-tostage calculations and starting from one of the ends of the column, but they require tedious calculations. We present here a simple design ...

Simultaneous Optimal Design and Operation of Multipurpose Batch Distillation Columns

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...

New Method for Designing Distillation Columns of Multicomponent Mixtures

This paper presents a series of calculation procedures for computer design of ternary distillation columns overcoming the iterative equilibrium calculations necessary in these kind of problems and, thus, reducing the calculation time. The proposed procedures include interpolation and intersection methods to solve the equilibrium equations and the mass and energy balances. The calculation progra...
