QVF DUAL STAGE
DISTILLATION SYSTEM
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 in 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.
