NaA membrane
1.Ethanol Dewatering
2.Methanol dehydration
3.Isopropanol dehydration

NaA membrane is an energy efficient combination of membrane permeation and evaporation. It's considered an attractive alternative to other separation methods for a variety of processes. For example, with the low temperatures and pressures involved in pervaporation, it often has cost and performance advantages for the separation of constant-boiling azeotropes. Pervaporation is also used for the dehydration of organic solvents and the removal of organics from aqueous streams. Additionally, pervaporation has emerged as a good choice for separation heat sensitive products.

Characteristics of the pervaporation process include:
* Low energy consumption
* No entrainer required, no contamination
* Permeate must be volatile at operating conditions
* Functions independent of vapor/liquid equilibrium
