Distillation Columns (APO02)

In Instrumentation

About this class



Learn the concepts of distillation including the components, operation, and principles of distillation systems. The relationship of process variables such as temperature and pressure is described in relation to the proper operation of a distillation column.





Prerequisites


This lesson is designed for participants familiar with process control. A knowledge of standard symbols used in process control diagrams, PID control systems, and various process control strategies is also recommended.

Description


This lesson introduces the concepts of distillation including the components, operation, and principles of distillation systems. The relationship of process variables such as temperature and pressure is described in relation to the proper operation of a distillation column. The lesson also presents basic and advanced distillation control strategies.

Objectives


Summarize the essential features of distillation. Describe the function of the main components of distillation. State the significance of vapor pressure, boiling point, temperature variables, pressure variables, and reflux in the distillation process. Distinguish between binary and multi-product distillation columns. State the importance of temperature, pressure, reflux, and feed control for a distillation process. Identify a process analyzer and describe its role in a distillation process. Describe the significance of material balance regulation to control product composition. Describe how cascade control is applied. Describe how feedforward control is applied.
