An Automated Distillation Column for the Unit Operations Laboratory
Abstract
A batch distillation apparatus has been designed and built for use in the undergraduate unit operations laboratory course. The column is fully automated and is accompanied by data acquisition and control software. A mixture of 1-propanol and 2-propanol is separated in the column, using either a constant distillate rate or constant composition mode of operation. The apparatus allows students to explore distillation and process control topics in an environment that closely resembles industrial practice.
