Upgrading biogas generated by anaerobic digesters to RNG requires integral cleaning of raw biogas to remove hydrogen sulfide (H2S), siloxanes, volatile organic contaminants (VOCs), water and carbon dioxide (CO2), nitrogen (N2) and oxygen (O2) to comply with the standards for injection into natural gas grids or use as gas vehicle fuel.

This webinar provides a background on the commercially available gas clean-up technologies and SulfaTrap LLC’s technology solutions for removing hard to remove contaminants (e.g., N2, O2 and organic sulfur compounds) that allow meeting the purity and heating value targets.
