Abstract

The present invention relates to a method and a system for desulfurization of biogas comprising of hydrogen sulfide. The method comprises the step of preparing a raw biogas and feeding the same to a scrubber tank (100), preparing bacteria and growing the bacteria inside a sphere shaped packing positioned in the scrubber tank (102), deploying bacteria into the aeration tank (103), and supplying oxygen to the aeration tank and the scrubber tank via a pump member (104). The resulting clean purified biogas then exits the scrubber tank (105). In accordance to another aspect of the present invention, there is provided a system for desulfurizing of a biogas. The system comprises a scrubber tank (200), an aeration tank (300), an inlet pipeline (201), an outlet pipeline (202), a drainage return pipeline (203), a first air pipeline (204b), a second air pipeline (204, 204a) a spray pipeline (205), a dispensing member (206), an air vent (207), and a pump member (208). The system is autonomously operated and environmental friendly. The method and system of the present invention results in high desulfurization rate of raw biogas.
