Please forward this error screen to 188. Biogas typically refers to a mixture of different gases produced by small scale biogas plant design pdf breakdown of organic matter in the absence of oxygen.
Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Biogas can be produced by anaerobic digestion with anaerobic organisms, which digest material inside a closed system, or fermentation of biodegradable materials. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.
Biogas can be compressed, the same way as natural gas is compressed to CNG, and used to power motor vehicles. It qualifies for renewable energy subsidies in some parts of the world.
Biogas can be cleaned and upgraded to natural gas standards, when it becomes bio-methane. Biogas is considered to be a renewable resource because its production-and-use cycle is continuous, and it generates no net carbon dioxide. Organic material grows, is converted and used and then regrows in a continually repeating cycle.
From a carbon perspective, as much carbon dioxide is absorbed from the atmosphere in the growth of the primary bio-resource as is released when the material is ultimately converted to energy. 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. Sohn AG are suitable for use in Zone 1 and 2 .
Other internal combustion engines such as gas turbines are suitable for the conversion of biogas into both electricity and heat. The digestate is the remaining inorganic matter that was not transformed into biogas. It can be used as an agricultural fertiliser.
