Liquid Contacting
Liquid contacting is the use of membrane modules for the transfer of gases to and from liquids. PermSelect® membranes are dense, without pores to clog, and do not leak (or "wet") as porous membranes can do.

• Blood oxygenation
  

• Degassing liquids
  • O2 removal from water
  • CO2 removal from water
  • Low surface tension liquids
• Adding gases to liquids and vapors to gases
  • Nitrogenation
  • Oxygenation
  • Carbonation
  • Media conditioning in cell culture bioreactors
  • Moisturizing air (humidification)

Pervaporation
Pervaporation is a membrane separation process that typically uses a vacuum to facilitate the transfer of a vaporizing compound through the PermSelect® membrane. It is most often used to separate liquids that have similar boiling points but different rates of transfer through the membrane material.

• Solvent dehydration
• De-alcoholization

Gas Separation
Gas separation is accomplished by a PermSelect® membrane due to the differences among gases in their ability to permeate through the silicone membrane (not based on their molecular sizes). The driving force of the gas transfer is the gas partial pressure differential across the membrane.

• CO2 capture
• VOC removal
• Dehydrating air (dehumidification)
• Nitrogen enrichment
• Oxygen enrichment
