.Typically 55% methane (CH4)45% carbon dioxide (CO2)H2S and H2O and trace gases
.Energy comes from methane only
.Energy value of methane 37.78MJ/Nm3
.Energy value of biogas 21MJ/Nm3
Anaerobic digestion technology
In the absence of dissolved oxygen, anaerobic microorganisms will tend to ferment biodegradable matter to carbon dioxide and methane which can be collected and use as a fuel. This process is called “anaerobic digestion”
What is Biodigester?
.Biodigester is a system that promotes decomposition of organic matter.
.It produces biogas, generated through the process of anaerobic digestion.
.Biogas generated can be used for cooking, heating, electricity generation, and running a vehicle.
BIOGAS TO POWER
Power is in short supply. 78,000MW planned in 11th Plan.
1.25 lac villages and 56 % of household are non electrified- Power is in big deficit.
Rural, decentralized and renewable power -A Priority.
Process industries need high quality and uninterrupted power.
Any expansion /New downstream projects will require additional, quality power.
Power generation/Cogeneration is becoming an important revenue stream.
