ARI’s AdvanSorb®-RNG processing technologies can handle virtually any feed gas specification, meet virtually any product gas specification, and do so efficiently and economically.
ARI’s AdvanSorb®-RNG upgrading system consists of 2 distinct processes.
• ARI’s AdvanSorb®-RNG CO2+ process, which removes H2S, VOCs, Siloxanes, carbon dioxide and water.
• ARI’s AdvanSorb®-RNG NRU+ process, which removes nitrogen and oxygen.
Landfill gas is most efficiently upgraded via two distinct PSA cycles. The first (CO2+) removes contaminants that are heavier than methane. The second (NRU+) removes contaminants that are lighter than methane. While these two systems can pair with other technology, they’re most efficient when paired together.
