Introduction

Due to high rate of population increase, large amount of fuel is required. So, a developed environment friendly system can assist to make fuel production better. In this project we are making a biogas plant in which the fuel gas is generated from cow dung and green waste. This fuel gas can be used for cooking purpose and also in gas engines to drive vehicles.

Properties of Biogas

The production of biogas is done by the anaerobic digestion of biodegradable materials like manure, green waste, sewage, plant material, municipal waste and crops. Biogas mainly consists of carbon dioxide, methane and small amounts of hydrogen sulphide, siloxanes, and moistures.

The general composition of Biogas

Methane gas- 55-70%

Carbon dioxide gas- 30-45%

Hydrogen Sulphide- 2-8%

Advantage

The gases methane, carbon monoxide and hydrogen can be oxidized with oxygen. This energy which is released allows biogas to be used as a fuel, purpose of heating and also can be used in a gas engine for the purpose of converting the energy into electricity and heat. Biogas can be used as natural gas by compressing and the generated gas is used to power motor vehicles.

Biogas is one of the renewable energy source. So, it can be used for renewable energy subsidies in some parts of the world. Cleaned biogas can be upgraded to natural gas when it is changed to bio methane. Biogas is normally be produced as landfill gas (LFG) or digested gas. A biogas plant is the often named as anaerobic digester because it treats farm wastes. Anaerobic digesters are used for producing biogas.
