In 1630 VAN HELMONT reported about the gas. IN 1808 H.DAVY made experiment with strawy manure and collect biogas. The 1 st sewage sludge digester was built in Exeter,U.K around the turn of the century. The 1 st sewage plan was built in BOMBAY in 1895. BIOGAS: BIOGAS Biogas is a methane rich flammable gas results from the decomposition of organic waste material,which is produced as a result of methane fermentation tanks to activity of methane bacteria. Organic compounds are changed into Biogas and inorganic compound in an oxygen free environment .WHERE DOES BIOGAS COMES FROM?: WHERE DOES BIOGAS COMES FROM? These are the sources which are responsible for the production of biogas:- VEGETATION, LANDFILLS, FARM and RANCH ANIMALS & SEWAGE.CHEMICAL COMPOSITION OF BIOGAS.: CHEMICAL COMPOSITION OF BIOGAS. COMPOUND METHANE CARBON DI-OXIDE NITROGEN HYDROGEN SULPHIDE OXYGEN PERCENTAGE 50-75% 25-50% 0-10% 0-1% 0-3% PRODUCTION OF BIOGAS: PRODUCTION OF BIOGAS This process can be divided into two phases:- ACID FORMING OR LIQUIFICATION -pH ranges from:5.1-6.8 Bacteria-Saprophytic bacteria METHAOGENESIS OR GASIFICATION- pH ranges from:7.2-7.4 Bacteria-Methanogens bacteriaPowerPoint Presentation: a A biogas plant TYPES OF BIOGAS PLANT: TYPES OF BIOGAS PLANT Fixed dome type Continous type Batch typeFACTORS AFFECTING BIOGAS PRODUCTION: FACTORS AFFECTING BIOGAS PRODUCTION TEMPERATURE C:N RATIO pH MOISTURE USES: USES Used to produce heat and power. to produce biodiesel after first processing as in standard petrol driven vehicle Used as a direct fuel for domestic cooking in the Eastern Nation ADVANTAGE AND DISADVNTAGE: ADVANTAGE AND DISADVNTAGE It is cheap in contrast to the other energy sources. Any biodegradable matter can be used as substrate. Environmental benefits on a global scale. Extra cost of installing technology to process and recycle wastes. Expensive to collect,harvest and store raw material. *THANK YOU*: * THANK YOU * You do not have the permission to view this presentation.
