What is it about?
Ethanol is an important industrial chemical requiring high energy input for its purification. We have shown, by comparing various configurations of the hybrid distillation-pervaporation/vapor permeation setups, that the synergistic effect of combining a membrane with a distillation column is not only beneficial for near 70% savings compared to art distillation but also produces absolute ethanol by overcoming the azeotropic barrier of the water-ethanol mixture.

Why is it important?
The key findings of our work would be a useful contribution to the process intensification concerning ethanol purification plants. The comparative study on the various types of membrane materials would help industries to make decisions in terms of selecting the membranes for long-term operations and estimating and comparing the overall capital and operational cost.
