Biogas storage

Fixed dome digesters are composed of a fermentation chamber for anaerobic digestion, feed and digestate pipes, and a fixed dome on the top for biogas storage. The reaction and biogas storage chambers are connected. In India, Kalia and Kanwar studied a 3 m ... 

The digested biomass will be delivered by a screw arranged under the digesters, further by bucket conveyor into storage tank and then removed it will be stacked or directly delivered onto the field. Since the operational test of the biogas plant is still in the phase of fulfilment, only some project data can be described.

Biogas composition is strongly dependent on the source and is within (50-75) % CH4, where the main contaminants are CO2 (up to 50 %) which lowers the calorific value of the gas and sulfuric acid (H2S) which could cause several problem on the plants and for human health on the plants it causes corrosion (compressors, gas storage tank and engines), while it is toxic after its inhalation [14-19],...
