Methane (ch4)
hydrocarbon present in the large quantity in
GOBAR GAS
Overview
Gobar gas is also known as Biogas mainly consists of
methane (CH4)
and
carbon dioxide (CO2) and also has a small amount of
hydrogen sulfide (H2s),
siloxanes, and
moisture. These all gases can be combusted and oxidized with oxygen. The energy released from the gases provides the gas to be used as the fuel. It can be used in the
fuel cells and it can be also transferred into
electric energy using the
gas engine by converting the gas to electric energy.
The gas can be compressed after removing the
carbon dioxide from it. The process of converting the gas to energy is the same as the
conversion of the natural gas and compressed into the CNG
which can be used to run the power vehicle.
Composition in the Biogas
The composition of the biogas depends on the substrate composition
also the
anaerobic reactor affects the process of making. The
landfill gas which is commercial in the purpose of the house contains
Methane gas in the
composition of about 50%. Whereas
advanced technology can
produce biogas which has a composition of about
55% to 60%.
Containments
Sulfur compound
The most common containment in the biogas is the hydrogen sulfide
(H2S) also the other compound including this present in the gas like
Thiols. This Sulphur compound is when yielded it became the corrosive compound
Sulphur dioxide (SO2) and
sulphuric acid (H2SO4) which is hazardous.
Ammonia (NH2)
Ammonia is produced from the organic compound containing Nitrogen,
Nitrous oxide, and amino acid in proteins.
Siloxanes
This is formed due to the presence of soap and detergents because they contain anaerobic decomposition
in them. During the release of siloxanes, it can combine with free oxygen in the combustion gas.
Production
The production of biogas is dependent mainly on the
two methods one is the
natural method
and the other is the
industrial method. It is produced with the help of methanogens and
sulfate-reducing
bacteria.
Naturally, it is produced with the help of the soil and the presence of the methanogens and most of it can be obtained from the wetland soil.
Industrially, it is produced with the help of Bio- Gas Plants which sometimes can be
called the anaerobic digester.
