Silica Gel
- Removes siloxanes
- Required to keep silica from plating onto hot surfaces during combustion as silicon dioxide (sand or glass)
- Silica Gel
- Good potential for removal of certain siloxanes from biogas
- High adsorption capacity
- Selectively retains organic silicon compounds
- Cooling
- Siloxanes can be removed from the cooled gas with condensation water
- Highly dependent on temperature and pressure
- Specialty Media (Al2O3, ZnO, etc.)
