Varec Biogas - Digester Gas Cleaning/ Drying Equipment

Varec Biogas offers a complete system that will remove moisture, H2S and siloxane in the gas. Moisture and particulate matter from biogas need to be removed when the biogas produced is utilized to run cogens. One particulate matter is siloxane, a common additive to everyday household items. During anaerobic digestion, silica is converted to silicon dioxide, or sand which overtime will reduce the efficiency, increase operating cost and cause failure for high capital equipment such as engine generators. Varec Biogas offers siloxane removal as part of our gas conditioning/drying system. H2S is a biogas constituent and need to be removed because it is highly corrosive to piping. More importantly, it will degrade the carbon-based filter used for siloxane removal.
