Coal, oil, natural gas and other traditional fossil fuel consumption continues to increase, which only exacerbated the depletion of fossil resources speed, but also brought many serious environmental problems. Growing energy needs and increasingly serious environmental pollution forced us to look for the way out to solve the energy crisis. Development and production of a variety of renewable energy sources to replace coal, oil and natural gas and other fossil fuels in the world to solve the energy shortage in the future an effective means, developed countries are committed to the development of efficient, non-polluting biomass utilization technology to protect national fossil energy resources, and ensure the sustainable development of the national economy. Bio-gas is an important source of biomass in renewable energy sources, which methane as the main component, mainly obtained through biogas purification. Since bio-gas can be an alternative fuel of petrochemical natural gas, it is possible to increase the development of methane gas supplies to alleviate the energy crisis. This paper describes a washing method is a common method for purifying biogas abroad. It uses CO2, CH4 difference in solubility in water to separate, is a relatively inexpensive method of purification, in particular it does not need to be regenerated water when its economy is more obvious. Study its control system to effectively save resources, improve efficiency, reduce human error, improve product quality. Bring safe and convenient operation.
