Dividing wall columns (DWCs) are an attractive option when the goals are to reduce energy consumption and capital investment for distillation processes. A major component in a DWC system is the reflux..

A simple auxiliary configuration and an extensive modeling study can mitigate the implementation risks of DWCs
Implement a constrained optimal control in a conventional level controller - Part 1
Novel tuning method enables a conventional PI controller to explicitly handle the three important operational constraints of a liquid level loop in an optimal manner as well as copes with a broad range of level control from tight to averaging control
Consider the generalized IMC-PID method for PID controller tuning of time-delay processes
This simple analytical method provides PID parameters to give a desired closed-loop response while available for any class of time-delay processes
