Biogas is a gaseous mixture of varied composition, generally composed of about 65 cent methane a high value fuel30 per cent carbon dioxide inert gas and traces of other gai it is produced from anaerobic fermentation in absence of air of organic waste. Anaerobic digestion of biogas production involves activity of three groups of organism i Solubilisation and Hydrolysis of organic components:
What Is Biogas or Gobar Gas? Biogas is a gas mixture which is generated when organic compounds are fermented in the absence of air anaerobic fermentation.
This gas mixture is mainly made of carbon dioxide CO2 and methane CH4. Methane is a combustible gas, which means it can be burned.
It can be used as a fuel for cooking and lighting. The Biological Gas Plant A plant to collect biological gas has five components: Organic matter such as manure human or animalduckweed or rice straw is brought into the fermentation chamber through the inlet.
The process of anaerobic fermentation will take place here to generate biological gas biogas. It will also produce a substrate rich in nutrients which can be used as organic fertilizer or fish feed. The processing of manure, organic rubbish and wastewater in the plant helps to keep the environment clean.
There is no longer any bad smell from sewage or livestock manure. Cooking by biogas is much cleaner than cooking over a wood fire, and there is no smoke to cause lung problems and eye diseases. The Technology Begin by loading the fermentation chamber with the materials to be fermented manure or other wastes.
You should begin with an initial load of - kg of materials for each cubic meter of the fermentation chamber. This needs to be supplemented by an additional 8- 10 kg each day for each cubic meter of the fermentation chamber. The gas output will be - liters for each cubic meter of the chamber. It could replace one liter of petrol to operate a W electric generator for two hours.
The Precautions The plant must be tested to make sure it is water-tight and gas-tight. Enough fresh material must be added before it is used every day. There must be a water source to provide enough water to clean the livestock pens regularly, to provide fresh material for the fermentation chamber system.
Each liter of manure needs 1 - 3 liters of water. The plant must be equipped with a safety valve or U-shaped barometer. Chemicals such as detergents or pesticides must not be put into the fermentation chamber.
After fresh manure and water is added to the fermentation chamber, the valve should be opened so the gas can escape. At this stage, the gas is mainly carbon dioxide.
This should be done once or twice, before the biogas plant comes into use for biogas production. The gas from the fermentation chamber is not used directly, but is stored in an auxiliary gas tank protected by a safety valve. It is this auxiliary gas tank, not the main gas tank, which is connected to any domestic appliances.Biogas is an alternate source of renewable energy.
A mixture of gases like methane plus carbon dioxide in a proportion of 40 is produced from the organic matter and is popularly known as biogas.
The gas is produced by the action of a mixed community of micro-organisms on organic matter through a. Write an essay on biogas and gobar gas energy. The programme is being implemented by the State Nodal Departments/State Nodal Agencies and Khadi and Village Industries Commission (KVIC), Biogas Development and Training Centers (BDTCs).
The energy prospect is generally assessed on the basis of available. commercial sources of energy i.e., fossil fuel like gas, coal, oil etc. Worldwide, there is a major transition underway in the energy sector.
The biogas is a renewable energy that can be used for heating, electricity, and many other operations that use a reciprocating internal combustion engine, such as GE Jenbacher or Caterpillar gas engines.

Biogas is a gaseous mixture of varied composition, generally composed of about 65 cent methane (a high value fuel), 30 per cent carbon dioxide (inert gas) and traces of other gai it is produced from anaerobic fermentation (in absence of air) of organic waste.
