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.)
