Optimal Operation and Control of Four-Product Dividing-Wall (Kaibel) Distillation Column

Optimal Operation of a Three-Product Dividing-Wall Column with Self-Optimizing Control Structure Design

This paper deals with optimal operation of a three-product Dividing-Wall Column (DWC). The main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. Exact local method is used to find the best controlled variables as single measurement or combination of measurements ...

Minimum Energy for the four-product Kaibel-column

For a four-component feed, Kaibel (1987) proposed a single dividing wall column (DWC) with two side-streams. We will show that an analytic minimal energy expression for the Kaibel-arrangement is straightforward to deduce based on the methods presented by Halvorsen (2001). The expression is very similar to the expression for the 3-product Petlyuk column. Minimum energy for the generalized nprodu...

Optimal control of a reactive distillation column

Optimal operation and stabilising control of the concentric heat-integrated distillation column (HIDiC)

A systematic control structure design method is applied on the concentric heatintegrated distillation column (HIDiC) separating benzene and toluene. A degrees of freedom analysis is provided for identifying potential manipulated and controlled variables. Optimal operation is mapped and active constraints are identified for constructing the supervisory control layer. The fundamental problem of o...
