Hydrogen sulfide (H₂S) removal
Biogas · wastewater · natural gas
Also called: sour gas, sewer odor
How it is removed
Physical adsorption on a re-agglomerated carbon, or caustic/metal-oxide impregnation that converts H₂S to a retained sulfur salt. Impregnated grades carry far higher capacity but are consumed rather than regenerated.
Recommended grades
SURSORB CAG
Re-agglomerated pelletized carbon for hydrogen sulfide removal
Specification →SURSORB PAG-10
Impregnated pelletized carbon for high-capacity H₂S removal
Specification →SURSORB ALKA
Alkaline-impregnated granular carbon for acid gases
Specification →SURSORB P-ALKA
Alkaline-impregnated pelletized carbon for sulfur compounds and acid gas
Specification →SURSORB MAG
Magnesium-oxide impregnated pelletized carbon for H₂S
Specification → The specification that decides it H₂S capacity in g/cc, and impregnation loading %
Test against your own duty
Capacity depends on inlet concentration, temperature, humidity, contact time and
competing species. Nothing here is an assurance that a grade will perform in your
service — it is a starting point for a trial.
Trial batches run from 1 to 10 tonnes.
