Purifications - AirScience Desulfurization System
AirScience Technologies offers two desulfurization processes. The Ferrachel II Iron chelate process for high gas flows and high inlet hydrogen sulfide concentrations. Dry scrubbing catalyst for low inlet hydrogen sulfide concentrations. In cases where hydrogen sulfide concentrations of less than 100 ppmv are required, a dry scrubbing catalyst stage is required.

AirScience - Model AST-AC/S01 - Biogas Dry Desulfurization Process System
Iron based desulfurization media has low cost and high desulfurization capacity as its main advantage, however the chemical reaction occurring during the capture of hydrogen sulfide tends to agglomerate the media pellets in larger chunks which render the spent media removal a time consuming chore. For this reason the tendency for landfill gas and biogas desulfurization has been to use activated carbon as the favored desulfurization ...
