- •
A control system is developed for a non-ideal azeotropic distillation process.
- •
Four control structures are evaluated for a triple-column pressure-swing process.
- •
Single-end temperature control is used in each column.
- •
Pressure-compensation improves performance in the low-pressure column.
- •
Disturbances in throughput and feed composition are adequately handled.
