Application Notes
Description : Pyridine-Picoline-Water Separation System
Process Flow Diagram
Process Description
A mixture of Pyridine, water and ?-picoline (2-methyl pyridine) is fed to first column. Pyridine-water azeotrope is removed from first column. Bottom stream, containing pyridine and picoline is separated in second column. Pure pyridine is collected as distillate and picoline is collected as bottom.
Water : 5-10 % (wt)
Pyridine : 40-45 % (wt)
Picoline : 40-45% (wt)
Design basis : Pyridine above 99% purity and picoline above 99.5 % Purity
Operating Conditions
Operating Pressure
Both columns are operating under atmospheric pressure
Column Internals :
Structured packing for the column
