What is a bio gas?What is a bio gas?
Mixture of methane and other gases produced from
the decompossion of organic materials.
Biogas is mainly a mixture of methane(50%-60%),
carbon di-oxide and hydrogen sulphide.
It is produced from bio mass from nature.
It is renewable source.
Calorific value 4500-5000 Kcal/m3
Ignition temperature 650°C
Octane rating 130

How it produces?How it produces?
Produced from biomass( leaves, animal dropping
and other agricultural waste) when it is fermented in
an anaerobic(oxygen free) manner.
Approximately 67 m3
of gas can be produced from 1
ton of biomass.
the decomposition process is natural and inevitable.
The bio gas formation mainly happens in
Bio gas production depends on various factors such
Composition of biogasComposition of biogas
Hydrogen Sulphide 5-10
Biogas plant(BGP)Biogas plant(BGP)
An air tight container to facilitate suitable
conditions to biomass for biogas production.
Also known as biogas digester, biogas reactor,
methane reactor or methane generator.
Provides biogas as well as bio-fertilizer.
Components of biogas plantComponents of biogas plant
Clear burning of fuel with less emission
Generated from waste
Displace fossil fuel
Reduce ground water contamination
Prevent door pollution
Boost rural economy
Solves the waste problem for dairy, hog and poultry farmers
Is corrosive in nature due to presence of
HS(hydrogen sulphate) if untreated
Flammable and explosive if accumulated in
Toxic if accumulated due to presence of carbon
as cooking gas for cooking purpose in homes,
schools and hotels etc.
As alternate fuel for automobile though not useful
up to the mark
In power generation unit of small capacity
