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.
