OVERVIEW
This purpose designed, electrically heated, QVF PILOT PLANT DUAL STAGE DISTILLATION SYSTEM by De Dietrich Process Systems permits selective stripping and rectification of aqueous aromatic solutions. A LabVIEW interface allows flexible control and data logging of feed rates, reflux rates, feed points, operating pressure and other process parameters. The system was designed using GMP guidelines where practical. To assure untainted product quality, all materials were selected to prevent trace contamination. Borosilicate glass was used for major components to provide maximum process visibility.
