Nonlinear Observers for Distillation Columns
IFAC Proceedings Volumes, 1994 Abstract A nonlinear observer, capable of accurate on-line-calculation of the product and feed composition of a binary distillation column is presented. The observer is based on a nonlinear reduced-order process model. In simulation studies the observer shows better performance, better robustness and easier adaption to real plant dynamics than an ...

New column configurations for pressure swing batch distillation I. Feasibility Studies [PDF]
, 2007 The feasibility of the pressure swing distillation in different batch column configurations is investigated. The method is based on the assumption of maximal separation. Besides studying the well known batch configurations (rectifier, stripper, middle

Simulation of the multicomponent distillation of spearmint essential oil by a predictive Soave-Redlich-Kwong equation of state and comparison with experiments [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2014 In this study, enrichment in major component of spearmint oil has been studied by continuous multicomponent distillation. A mathematical model was evaluated to predict the enrichment by multicomponent distillation of spearmint oil.

Dynamic models for start-up operations of batch distillation columns with experimental validation [PDF]
, 2004 The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally
