High Performing, Low Nitrogen Content H₂S Scavenger

Hydrogen sulfide (H₂S) is a toxic, corrosive gas that’s encountered in the oil and gas industry. H₂S is soluble in both water and hydrocarbon and thus an optimal scavenger needs to scavenge H₂S from both. Operators are faced with several major issues when producing oil and gas containing H₂S including HSE and regulatory concerns, along with multiple operational issues. A variety of products are available for the removal of H₂S from gas and crude oil streams, the most common being triazine based H₂S scavengers.

Lubrizol’s SULFA-CLEAR™ 8846 hydrogen sulfide scavenger offers our customers a fast acting, higher efficiency alternative to conventional triazine. SULFA-CLEAR 8846 reduces many process issues associated with conventional triazine, increases crude value by minimizing nitrogen contamination, decreases transportation cost with lower dosage rates and exhibits a better environmental profile.
