GC Sulfursorb

Catalytic Activated Carbon for H2S Treatment

The GC Sulfursorb series of activated carbon are non-impregnated, activated carbons derived from hardwood or bituminous coal which have been specially developed for the removal of Hydrogen Sulfide and Sulfur compounds from vapor streams. All are well suited for use in sewage treatment plants and pumping stations where these compounds are typically found. GC Sulfursorb carbons give you the high loading rates of impregnated carbons without the thermal risks associated with some chemically treated carbons. In addition, by water washing these products, some of their H2S capacity can be restored.

*Standard packaging is in 25 or 500 kg. bags. Other packaging is available upon request.

*H2S capacity is measured using ASTM standard method D6646-01. Testing requires passing a moist air stream containing 1% by volume H2S through an appropriately sized column (per ASTM requirements) packed with activated carbon and monitoring to a 50 ppmv H2S adsorbed per gram of activated carbon.

Wet activated carbon removes oxygen from air causing a severe hazard to workers inside carbon vessels. Confined space/low oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable Local, State and Federal guidelines.
