pervaporation

Recently, a number of organophilic Pervaporation membranes have been introduced to the market.

All processes except for pervaporation involve no phase change.

The commercially most successful pervaporation membrane system to date is based on polyvinyl alcohol.

The further separation is then accomplished with a membrane operated either in vapor permeation or pervaporation mode.

These include gas stripping, pervaporation, membrane extraction, adsorption, and reverse osmosis.

Organophilic Pervaporation membranes can be used for the separation of organic-organic mixtures, e.g.:

Other products fabricated with this process include various ceramic membranes for microfiltration, ultrafiltration, nanofiltration, pervaporation and reverse osmosis.

Vapor permeation uses a vapor membrane feed and pervaporation uses a liquid membrane feed.

More recently, I and others developed new microfilters that make fermentation more efficient, and also pervaporation membranes that afford a particularly energy-efficient means of separating alcohol-water mixtures.

The widely used membrane processes include microfiltration, ultrafiltration, nanofiltration, reverse osmosis, electrolysis, dialysis, electrodialysis, gas separation, vapor permeation, pervaporation, membrane distillation, and membrane contactors.

The pervaporation method uses a membrane that is more permeable to the one constituent than to the another to separate the constituents of an azeotrope as it passes from liquid to vapor phase.

Within this branch, research is conducted on green chemistry and engineering, metals recovery and recycling, pervaporation, watershed environmental and impact analysis, chemical process stimulation for waste reduction, and quantitative structure activity relationship.
