Distillation Pressure Controls: Principles and Troubleshooting

Pressure control is the most important control in distillation. Pressure affects everything: vaporization, condensation, temperatures, volatilities, hydraulic loadings, proximity to the relief setting. If column pressure jumps up and down the column is unsteady. This makes pressure control the No. 1 priority in a distillation control system.
Generally, there are three classes of pressure control methods: manipulating the vapor product rate, flooded condensers, and manipulating the coolant rate. Each one of them can be made to work well if configured correctly, and can be unstable if not. The devil is in the details.
This presentation outlines key principles of distillation pressure controls, and several lessons learned from experiences with troublesome systems. It is our hope that this presentation will provide engineers with insight that will help identify and rectify some common pressure control problems.
