Extracting Methane Gas

Methane, one of the main components in natural gas, can be produced from a very simple thing, such as house-hold waste or garbage. First of all we put the garbage in a warming bed. In the warming bed the garbage is selected, which one as methane source and which one as fertilizer. The garbage as methane source will go to the dirt trap, where the garbage and the methane are separated. Then the methane will continue to the gas indicator. Gas indicator is a big tank containing water with a sealed top. When there are too many methane gas produced which can caused the pressure of the gas is too high, the excess gas is brought to the pressure release. It is similar to the gas indicator, but it has no sealed top. Finally, the remaining methane gas is contained in the gas holder. Gas holder is a device containing several inner tubes, with weights on top of it to increase the gas pressure.
