Bio gas

  1. 1. BiogasBiogas As an alternative fuel
  2. 2. 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. 2
  3. 3. propertiesproperties Property value Calorific value 4500-5000 Kcal/m3 Ignition temperature 650°C Octane rating 130 Air to fuel ratio(stoichiometric) 10:1 Explosive limit to air by volume 5-15 3
  4. 4. 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. 4
  5. 5. The bio gas formation mainly happens in three stages. 5
  6. 6. Bio gas production depends on various factors such as 6
  7. 7. Composition of biogasComposition of biogas 7 Constituent Percentage Methane 50-60 CO2 30-45 Hydrogen Sulphide 5-10 Nitrogen 0.5-0.7 Water trace
  8. 8. 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. 8

  11. 11. AdvantagesAdvantages  Clear burning of fuel with less emission  Low cost  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 11
  12. 12. DisadvantagesDisadvantages Is corrosive in nature due to presence of HS(hydrogen sulphate) if untreated Flammable and explosive if accumulated in enclosed space Toxic if accumulated due to presence of carbon monoxide 12
  13. 13. UsesUses 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 13
