Feasibility of an integrated biogas scrubber for a swine manure digester

Laboratory experiments were conducted to study a scrubbing system for the removal of carbon dioxide (CO$\sb2$) from the biogas produced by a swine manure anaerobic digester. This innovative scrubbing system was included in the original design of an existing full-scale digester, but had never been tested. The principle of operation was that ammonia (NH$\sb3$) gas would be desorbed from the influent manure in an enclosed preheating vessel, the mix tank, and subsequently reabsorbed in a separate scrub tank full of water (charging cycle). The biogas was passed through this charged scrubbing solution (scrubbing cycle). The CO$\sb2$ would then be absorbed from the biogas stream, producing a higher quality gas in terms of methane content.
