Question

how is biogas produced what are its uses

Answer 1

Plant and animal wastes (dung), vegetable wastes, sewage are decomposed in absence of oxygen to produce Biogas

Since the source of these fuels is animal dung, the source of these fuels is called Biomass.

It is commonly called Gobar-gas

Biogas Plant

Mixing tank : Cow dung and water is mixed together to form slurrywhich is fed into the mixing tank.

Digester : The slurry is passed on to the digester which is a completely sealed chamber with no oxygen. Here anaerobic decomposition of slurry takes place.

Gas tank: The anaerobic decomposition releases gases such as methane, carbon-di-oxide, hydrogen and hydrogen sulphidewhich are collected in the Gas tank and drawn out through the gas outlet

Advantages of Biogas



·         Since India has a large rural population and large live-stock population, this fuel is easily available.

·         Excellent fuel with reasonable heating efficiency

·         Burns without smoke

·         Does not leave residue

·         Slurry residue can be used as a manure

·         Environment friendly

 Disadvantages of Biogas

·         Less heating efficiencycompared to other sources.

·         Releases gases (carbon, hydrogen, hydrogen sulphide, methane) which can corrode metal parts of the biogas plant itself.

·         It cannot be constructed easily becauseof the inputs are cow dung (and other wastes) which are available mostly in rural parts only.
