Pervaporation & Vapor Permeation is an energy efficient combination of membrane permeation and evaporation. It's considered an attractive alternative to other separation methods like Extractive Distillation,Molecular Sieve for a variety of processes. Pervaporation is used for the dehydration of organic solvents and the removal of organics from aqueous streams. TFT offer the PV process with the ceramic membranes.
High performance Zeolite PV membranes have been successfully developed and applied in China since 2007. This new technology have been widely accepted in many industries like pharmaceutical, semi-conductivity, petrol chemical,etc. It have been prooved from many projects that PV&VP technology has many advantages than traditional dehydration processes like evaporation, distillation, and zeolite adoption.
Process Characteristics of PV/VP:
* Low energy consumption, less running cost
* No entrainer required, no contamination to product
* Easy operation and less maintenance
* Functions independent of vapor/liquid equilibrium
* Reliable treated solvent quality
* Less labor cost
* Less waste discharge
