Abstract

The pressure swing separation of a binary minimum azeotrope (n-pentane-acetone) in a double column batch stripper is studied by rigorous simulation. For controlling the product compositions a simple scheme is presented. On the basis of temperatures of bottoms product PID controllers manipulate their flow rates varying the reboil ratios. The controllers are tuned. The influence of the most important operational parameter (division ratio of liquid leaving the common top vessel) is investigated. For rigorous simulation calculations a professional dynamic flowsheet simulator is applied.
