Comparison of two type of reactors in biogas upgrading by chemical absorptiom methode

Biogas from anaerobic digestion of biological wastes is a renewable energy resource. It has been used to provide heat, shaft power and electricity. Typical biogas contains 50-65% methane (CH4), 30-45% carbon dioxide (CO2), moisture and traces of hydrogen sulfide (H2S). Presence of CO2 and H2S in biogas affects engine performance adversely. Reducing CO2 and H2S content will significantly improve quality of biogas. In this study two type of reactors include packed column and tank reactor were employed and The CO2 absorption characteristics by these two reactor were experimentally examined under various operating conditions. The results indicated that the packed columns are more efficient in biogas upgrading than tank reactors.
