Methane Process

Methane is a chemical compound with the molecular formula CH₄. It is the simplest alkane, and the principal component of natural gas, about 97% by volume. It is a colorless, odorless gas (at normal temperature and pressure) and not a liquid nor solid. The major source of methane is extraction from geological deposits known as natural gas fields.. Apart from gas fields an alternative method of obtaining methane is via biogas generated by the fermentation of organic matter including manure, wastewater sludge, municipal solid waste, or any other biodegradable feedstock, under anaerobic conditions. Here is a process of producing methane from waste as it main source.

To have purified methane gas, we have to separate it from other components of waste. This process has several posts. At the first post, warming bed, the waste is heated to separate it with other heavy components of waste. While methane goes to next process, the other waste’ components can fertilize your plants as it passes few processes. Then, at the next post, the dirt trap, the remaining dirt is separated from the methane by sedimentation. The dirt stays in the dirt trap and the gas flows to the next cabin, gas indicator. Half part of this sealed cabin is fulfilled by water and other by air. After the methane gas is flowed into the water, there will be methane bubbles. Other gas will be trapped in the water. The methane bubbles goes up to the top of the cabin and continue its journey to the next post. In this post, cabin is fulfilled by water until the top of the cabin which is open to air. The flower pipe enters the cabin about 8 cm in depth. When the pressure is high, the excess gas will flow into the water in the cabin and then goes to the open air. After all those process, the purified methane gas is flowed into the gas holder. It is kept in tubes which are weightened to increase the gas’ pressure. The flower pipe ends with a tap.Whenever we need methane gas, just open the tap and the gas will come out.
