Membrane based process for fluid separation – CLOSED

- Closed -


The principle of the invention is to separate the chosen mixture (for instance water/ethanol) into its basic constituent by flowing it through a membrane semi- permeable to alcohols or alkanes. In the case of water/ethanol, only ethanol is able to flow through the membrane.

The process should operate at a moderate energetical cost.

Competitive advantage of the technology and state of the industrial property:

Different techniques exist for water/ethanol separation. But on the contrary to what exists, the process does not require a high energy input through heating, or the addition of supplementary chemicals.


Several advantages:

  • Moderate energetical cost;
  • Relative easiness of setting up a scaled-up apparatus;
  • Requirement of lower pressure compared to reverse osmosis when pure fluids are desired.


This invention is patented worldwide through a PCT application.
