Biogas & Landfill Gas

Hydrogen sulfide and other sulfurs are the most common contaminant 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.

Volatile organic compounds can lead to harmful emissions and difficulty meeting gas quality specifications. Axens offers VOC removal solutions as a polishing step to complement other treatment technologies.

Mercury can be present at trace levels in landfill gas. Its removal is crucial to prevent HSE-related issues, corrosion problems, and damage to downstream treatment technologies.

Removal of moisture is a standard unit operation in Biogas and Landfill Gas plants. Axens offers dehydration/drying adsorbents to meet stringent moisture specifications with minimal energy required.

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 products in Temperature Swing Adsorption (TSA) units to completely and reliably remove siloxanes.

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.

Axens acquired a stake in Arol Energy in 2019. Arol Energy offers the following processes which are specialized for the purification of biogas:

• AE-Amine line: Biogas upgrading using a high-performance chemical scrubbing process with a very low energy demand that meets the strictest technical specifications.
• AE-Membrane & AE-Compact lines : Biogas upgrading based on membrane gas separation combining simplicity and performance in a very compact installation. Arol Energy also provides prefabricated boilers to cover head demand on site with complete heat integration with its biogas purification units.
