Biogas is obtained through the anaerobic decomposition (putrefaction) of organic matter. It contains methane (CH4) in varying proportions, ranging from 35% to 70%, a proportion which largely depends on production methods and the materials involved in the process. This methane concentration is what enables biogas to be used as fuel. The release of methane into the atmosphere contributes to an increase in the greenhouse effect and its capacity to pollute is 21 times greater than that of CO2.
Biogas cleaning / conditioning - A requirement for optimal functioning of CHP systems
The use of biogas as a fuel or raw material for the production of other goods is the best option, not only because it avoids emissions of methane gas to the atmosphere but also because it reduces emissions of other greenhouse gases that would occur as a result of the combustion of fossil fuels.
Biogas must be cleaned for optimum operation and performance of machines (engines, turbines, boilers, fuel cells, etc.) related to its use as a fuel.
In this way, we achieve reductions in the costs of maintaining (repair and oil changes) the machines used at this type of facility; extending the life of machinery and equipment used for pumping, extraction and compression (blowers and compressors).
