Adaptive Predictive Control of a Distillation Column [PDF]

open access: yes, 1999
Distillation processes reveal complicated multivariable nonlinear dynamics for which it is difficult to design a high-performance control system. This paper proposes an adaptive control scheme for a distillation column.

Energy-Efficient Diabatic Distillation Using a Horizontal Distillation Column

open access: yes, 2016
A conventional distillation column has two limitations causing heavy energy demand: short residence time of liquid flow and excessive vapor flow due to the external reflux flow.

Tuning of Distillation Column Control [PDF]

open access: yes, 2015
Distillation column is one of the most important equipment in a chemical industry. It is quite a challenge to control both the composition of the bottom and top product without affecting the composition of one another.

Insights into batch extractive distillation using a middle vessel column

open access: yes, 2018
: "Researchers have begun to study a batch column with simultaneous top and bottom products, sometimes called a middle vessel column. The column is similar to a continuous column in that it has both rectifying and stripping sections.

Methanol control and aromatic preservation in producing wine spirit from east Asian species

open access: yesFood Chemistry: X
High-acidity, low-sugar, neutral-aromatic grapes from East Asian species show great potential for spirit production. However, their high methyl-esterified pectin content poses a risk of methanol overload.
