Pervaporation & Vapor Permeation Membrane


Schematic Diagram

Vacuum method

Sweeping method

Pervaporation is derived from the two steps of the process, permeation through the non-porous membrane by the permeate, then its evaporation into the vapor phase which is condensed into liquid phase. Membrane acts as a selective barrier between the two phases, the liquid-phase feed and the vapor-phase permeate. It allows the desired component of the liquid feed to transfer through it by vaporization. Pervaporation technology could be applied to the separation of alcohol/water mixture, organic compound/water mixture and vapor permeation process. AIRRANE is currently providing O&M service by installing IPA recycling failures within the semiconductor plant site. IPA recycling can reduce wastewater and reuse IPA (isopropyl alcohol) in the semiconductor industry.

Key Applications

Pervaporation/Vapor Permeation

● Dehydration of water/organic liquid mixture

● Purification of water/alcohol mixture

● Removal of VOCs from water/organic liquid mixture

● Separation of organic/organic liquid mixture

● Monomer recovery from polymerization process

● Process yield and efficiency increase for dehydration of condensation reactions

Why Membrane Pervaporation/Vapor Permeation?

● Low-cost separation without chemical additives

● Separation of azeotrope mixtures

● Effective separation even with small gap of boiling points of mixture

● The feed mixtures to be treated may be supplied in liquid (PV) or

vapor form (VP)

● Low energy consumption system for vapor permeation

● Compact size facility design

● Easy and quick start-up system

● High purity permeates attainable
