Biogas Upgradation

The methane contents in biogas vary with type of organic waste which is being treated and method of producing biogas. Various organic wastes or biomass have specific types of proteins and lignin contents which sometimes are difficult to degrade and result in a partial decomposition and thus smaller amount of methane content are achieved in biogas. For instance, fibrous biomass such as sugarcane bagasse or trach are stiff and it is difficult to break the inner cells during digestion process which inhibit or limit methanogens (archaeal community) to produce methane, and eventually the final product has around 40% of methane but up to 60% of carbon dioxide. In such circumstances, feeding low methane content biogas into the gen-set (to produce electricity) would result in partial combustion with lower calorific value or would never let combustion process to start for the gen-set.


Since methane is the key gas in biogas which will burn during combustion process, the upgradation of biogas is vital to enrich methane in it and remove carbon dioxide as much as possible. This will not only improve the combustion quality but also result in higher calorific values.


There are several methods to reduce or remove carbon dioxide from biogas such as water scrubbing or ferrous oxide scrubbing. Both type of processes will remove carbon dioxide as a compound and thus will increase methane content in biogas.


If you looking to improve the quality of biogas by removing carbon dioxide then contact PROBEC Australia who can help you in assessing the biogas quality, process improvement, and biogas upgradation.
