What is a biogas plant?

Biogas plant is anaerobic digent that produces biogas from animal waste or energy crops. Energy crops are cheap crops grown for biofuels rather than food. Biofuels are liquid, gaseous or solid fuel made of live or recently dead organic material known as biomass, unlike fossil fuels, which consist of ancient biological materials. Biogas is a type of biofuel created through anaerobic or oxygen digestion of organic matter with bacteria. The biogas plant consists of a hood and a gas holder. Bacteria in the digestor tank decompose waste and, as decomposed, gases such as carbon monoxide, methane, hydrogen and nitrogen are released. Through the pressure system, the gas holder performs the current of these gases up into the hole in the drum. The hole is specially designed to allow gases to go freely into the holder and forbid the gases in the leak back to the digestor. Gases are later in a controlled environmentLenny or reacted, with oxygen to create a source of energy for processes such as heating and vehicle drive.

Biogas construction may vary depending on the amount of gas, the amount of waste at hand and whether the digester is designed for dose feed or continuous feeding. The feeding systems of feeding are mainly used by solid waste, which are added to the tank in installments, and the models of continuous feeding mostly feed on liquid to the digester. The biogas plant can be constructed either above or underground, with advantages and disadvantages for both models. The above -ground biogas plant is easier to maintain and benefit from solar heating, but requires more care in the construction industry, because it must be built to handle the internal pressure of the digestor. The biogas plant underground is cheaper on the construction and is easier to feed, but it is more difficult to maintain it.

to facilitate rapid decomposition with optimalGas production is often kept between 29 ° C and 41 ° C (84.2 ° F-105.8 ° F). In an effort to neutralize the porridge, more acidic carbon dioxide will be created, which is the required gas. The porridge in the tank must also often be mixed to prevent the formation of a hard cortex at the top of the waste. The bark can capture the porridge gases and prevent the capabilities of the machine to use the gases.

Biogas is increasingly preferred to fossil fuels or fuels made of ancient organic matter such as coal or oil. Carbon is an important part of a healthy atmosphere in small quantities, but when too much is added to the circulation, it becomes problematic. The carbon contained in fossil fuels was buried for such a long time that it is no longer part of the carbon cycle. When released by combustion of fossil fuels, it increases the concentration of carbon. Biogas, howeverera.

In addition to carbon performance, biogas fuel is often preferred by fossil fuels because it is a low cost, renewable energy source and uses otherwise unnecessary materials. Biogas is also a valuable source of energy for developing countries because it can be made in small places. However, biogas fuel also has its critics. Some argue that energy crops reduce food agriculture and create a global lack of food. Biofuels can also cause deforestation, water pollution, soil erosion and a negative economic impact on oil producing nations.
