Biogas Purification Process to Increase Gen—Set Efficiency

Because of global issue about limited energy, biogas was one of alternative energy and save energy in the world which produced from biomass especially from cow manure. Most of biogas which produced from cow manure contains 40–75% methane as energy resources and another gas as impurities. Methane concentration of biogas has relation with biogas energy value, especially for application as fuel of electricity conversion using gen‐set. For increasing gen‐set efficiency can be held by increasing methane concentration of biogas using biogas purification process. Biogas purification process can be held by adsorption system which using activated zeolite as absorber. After biogas through the purification system, methane concentration was increasing and impacting to gen‐set efficiency especially voltage value was increasing until 22 times in average better than without purification and keeping power stability, so it will produce electricity conversion until 39,07% of practical and 38,09% of equation calculation from maximum electric power output of gen‐set.
