PROJECT DESCRIPTION

The Project is to design and to develop a new unit able to separate three solvents (alcohols) mixed with salts and water with a 99.5% specification on purity.

OUR METHODOLOGY

The methodology developed by Processium was based on:

• Issue a thermodynamics diagnosis (azeotrope between two alcohols in one hand and water on the other hand).
• Process synthesis to propose processes based on pressure swing distillation, liquid-liquid extraction (including solvent selection), extractive distillation and azeotropic distillation.
• Sizing of the best process.
• Laboratory and pilot scale validation of process sizing.

RESULTS

On the basis of technical package issued by Processium, the new unit had been built is still running.
