Biogas Filter Need in Fixed Dome Model Biogas Plant: A Case Study Province1 of Nepal

Hydrogen Sulfide is a rotten smelling corrosive gas. About 0.821 to 328.5 m³/biodigester Hydrogen Sulfide gas is released during 20 years from 6 m³ biodigester. About 349031 to 139612500 m³ of Hydrogen Sulfide gas is released from all systems installed in Nepal considering that such a system runs for a typical time of 20 years. There is a trend of using the roof of sheet metal in the rural area of Nepal. Sheet metal is composed of iron galvanized with zinc. Sheet metal is eaten by the Hydrogen Sulfide gas continuously. Finally, it gets internal cracking, pitting leads to a hole. Ultimately, the end-user has to replace it. When Hydrogen Sulfide gas is released into the environment, it causes environmental hazards. There is a need to use a biogas filter that absorbs the H₂S gas installed in domestic model biogas plants worldwide.
