The Project is to design and to develop a new unit able to separate two solvents (alcohol and ketone) mixed with salts and water with a 99.9% specification on purity.


The methodology developed by Processium was based on:

  • Issue a thermodynamics diagnosis.
  • Process synthesis to propose processes based on pressure swing distillation, liquid-liquid extraction, extractive distillation and azeotropic distillation.
  • Sizing of the best process.
  • Laboratory and pilot scale validation of process sizing.
  • Production of samples.


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