EXTRACTING METHANE

Methane is derived from the house hold waste. The waste enters a warming bed for warming. The warming process produces methane used for fertilizer and methane that needs more processing. The fertilizer can be used directly without any further process but the other methane product must be processed to get the pure methane. First, the methane enters a dirt trap to separate the dirt phase and gas phase. Then, the gas phase flows through pipe to a sealed tank with water inside that acts as the gas indicator. The product from this reaction flows to 2 pipes. The first pipe carries the gas to a pressure release tank for decreasing the pressure of gas excess when the pressure is high while another pipe carries it to the inner tubes with weight on the top to increase the pressure of the gas. Finally, the rest gas is carried to a gas holder that will flow it to the tap where we can get the pure methane just by opening the tap.
