The GWE SULFURIX™ family of scrubbers for effective biogas desulfurization

Biogas is classified as a “dirty” gas, containing a number of different gases, not only the sought-after methane component. Hydrogen sulfide is nearly always present and often must be removed before the biogas can be utilized in power generators or modern steam boilers. There are two primary reasons for this: to reduce sulfur dioxide (SO2) emissions and comply with local air quality regulations, and to ensure the optimal operation and corrosion prevention within the biogas combustion and exhaust systems.

There are several methods by which biogas can be scrubbed, including absorbent media, biological treatment, and chemical systems. GWE offers two proprietary technologies that will efficiently desulfurize your biogas stream, as well as conventional activated carbon filters for tertiary polishing of the gas when very low H2S levels are required.

For over 15 years, GWE’s desulfurization technologies have been some of the most effective systems on the market for treating biogas with 0.5 to 5% H2S concentrations.
