Gas cleaning in activated carbon filters - How much moisture is needed and why?
Biogas and sewage (typically around 60% CH4, rest CO2) gas is typically treated in activated carbon (ac) filters to remove H2S and siloxanes. The ac filters need a small amount of oxygen (>0,4%) to work. Additionally, the moisture content needs to…

Is it feasible to compress cleaned Biogas?
Biogas generated from anaerobic digestion mainly contains around 50-60% $CH_4$, 35-40% $CO_2$, small amount of $N_2$, saturated $H_2O$ and trace of $H_2S$. It's upgraded to automotive fuel grade by removing $H_2S$ up to, $H_2O$ and $CO_2$. The…
