Non-Porous Perfluoropolymer Membranes
Non-porous perfluoropolymer membranes can be used to remove dissolved gases from a liquid. This can be done for a number of reasons including unit operations (e.g., removal of dissolved oxygen in your fuel) or for sensing purposes (e.g., removal of gases from transformer oil to sense for degradation and wear on the transformer). In both cases, the removal of gases can be done in real-time, streamlining the process.
Degassing is useful in many applications for both unit operations and for sensing requirements. In sensing applications, the goal of the degassing or gas extraction is to remove sufficient gas to allow sensing of the gases’ particular makeup. This is used in mission-critical environments including:
- Power generation
- Power distribution
- Chemical detection
In the unit operations example, the degassing improves the ability of the liquid to perform its required task. This is important in:
- Fuels
- Solvent recycling
- Lubricating fluids
- Transformer oils
- Inkjet printing inks
- High Performance Liquid Chromatography (HPLC)
Why are CMS membranes ideal for gas extraction?
Stable and long-lasting – products have been immersed continuously in transformer oil and performing gas extraction functions in those products for >15 years with no failures
Highly permeable to gases – provides high flux of gases through the membrane to a sensor or for unit operation of gas removal. In either application, the high flux allows for a compact gas removal system
Chemically and thermally stable – provides a wide range of operating conditions for gas extraction
