Biogas is produced by bacteria through the bio-degradation of organic material under anaerobic conditions. Natural generation of biogas is an important part of bio-geochemical carbon cycle. It can be used both in rural and urban areas.
The composition of biogas and concentration (by component volume) includes: Methane (55-60%), Carbon (iv) Oxide (35-40%), water (2-7%), Hydrogen Sulphide (20-20,000ppm (2%)), Ammonia (0-0.05%), Nitrogen (0.2%), Oxygen (0.2%), Hydrogen (0-1%)
General features of biogas are:
- Energy content 6-6.5KWh/m3
- Fuel equivalent 0.6-0.65/oil/m3 biogas
- Explosion limits 6-12 % biogas in air
- Ignition temperature 650-750oC
- Critical temperature -82.5oC
- Critical pressure 75-89 bar
- Normal density 1.2 kg/m3
- Smell Bad eggs
