AxTrap for Sulfur/H2S Removal
AxTrap for Sulfur/H2S Removal
Hydrogen sulfide and other sulfurs are the most common contaminants in Biogas and Landfill Gas. Axens offers a range of adsorbent products to bring a simple, reliable, and cost-effective solution for a wide variety of treatment challenges.

AxSorb for Siloxane Removal
AxSorb for Siloxane Removal
Siloxanes are a growing contaminant of concern in Biogas and Landfill Gas plants. If not removed, then siloxanes could damage downstream equipment. Axens offers activated alumina pro-ducts in Temperature Swing Adsorption (TSA) units to completely and reliably remove siloxanes.

AxSorb for Carbon Dioxide Removal
Removal of carbon dioxide to purify methane is required in RNG plants. Axens offers molecular sieve and alumina products in Pressure Swing Adsorption (PSA) units for minimum coadsorption and maximum performance.
