Renewable Natural Gas (RNG) consists of multiple names: bio-methane, swamp gas, landfill gas, and digester gas. This gaseous discharge is a product of anaerobic digestion which is the decomposition of waste material without the presence of oxygen. In addition, this product, when processed to purity standards, can be used as renewable gas and can be used as a fuel for plant heaters, power generators, and natural gas vehicles.
Captured RNG from an anaerobic process reduces emissions to the atmosphere and is used as a green energy fuel. RNG production is a result of anaerobic digestion whereby the solids are converted to methane and carbon dioxide gas. Municipalities around the globe are significantly reducing their operating costs and improving efficiency by harnessing a byproduct of the anaerobic process. They are turning to biogas co-generation as a alternate energy source.
The biogas can be processed into a high quality fuel for vehicle and power generation.
Scrubbers are needed for the removal of Hydrogen Sulfide and sulfur species, moisture, Siloxanes, and carbon dioxide in some applications.
To confirm the quality of the cleaned biogas, the Mustang® Biogas Sampling System will sample the gas prior to and after the gas cleaning process. This begins at the sample probe located in the raw gas pipeline. The sample tubing and the sample conditioning panel are electrically heated to slightly above the sample dew point to prevent loss of any gas components. Analyzing prior to and after the gas cleaning will help determine the performance of the cleaning process and also determine the scheduling of the filter media cleaning and or replacements.
