How to maximize the methane yield of biogas plants using the FOS/TAC ratio as a control parameter
Monitoring the ratio of free organic acids (FOS) to total inorganic carbonate (TAC) is the best practice how to monitor the fermentation process in biogas reactors. Keeping this ratio stable within a defined window is key to maximizing the methane output and hence the profitability of a biogas plant. A free white paper from Metrohm takes a closer look at the chemistry behind the biogas ...

Biogas desulfurization | Tailor-made desulfurization process to ensure system operation safety
Biogas purification is an indispensable part of the biogas production process, because H2S in biogas is a flammable colorless gas, and its aqueous solution is called hydrosulfuric acid, which is corrosive. Biogas desulfurization purification equipment is mainly used to remove H2S in biogas, prevent its corrosion to biogas combustion equipment and pipelines, and extend the service life of the ...
