Biogas purification and H2S removal
CrumRubber™ patented technology is a biological system which utilizes inert filtering media, Up-cycled from rubber waste, in conjunction with specialized bacteria’s to remove high levels of H2S by converting it into sulphate and elemental Sulphur.
The technology has been proven to reduce H2S and volatile organic siloxane concentrations prior to a combustion gas engine in order to preserve its availability (time/life), extend time oil change and decoking intervals and reduce costs associated with frequent activated carbon change outs.
CrumRubber™ technology is also suitable as a pre-treatment stage of traditional air treatment solutions for the removal of VOCs and related odor, in addition to hydrogen sulphide. Typical removal efficiencies for levels of H2S from 10 to 4000 ppm range from 80 to in excess of 99%. This technology can also be used in conjunction with our other technologies to create a robust treatment chain suitable for a wide range of compounds. In the municipal sector CrumRubber’s application with MonaShell® in a two-stage configuration are a perfect fit for lift stations, and wastewater treatment plant process odor control. The process provides superior treatment, low cost of ownership with no chemical additives.
The filtering media is continuously regenerated by the action of recirculating water and a controlled purge. CrumRubber™ can be supplied as a skid-mounted modular system made by high grade corrosion resistant material equipped with removable covers for media replacement.
