Hydrogen Sulfide Scavengers

Production and processing of oil and gas resources can lead to generation of hydrogen sulfide gas (H₂S), both occurring naturally through the reduction of calcium sulfate in the reservoir and through bacterial contamination via stimulation or water injection. 

Uncontrolled H₂S can create several operational challenges related to safety, corrosion, separation, regulatory and odor. The application of effective H₂S scavenger chemistries can eliminate these challenges, allowing for optimal performance of your system and a reduction in HSE exposure. Lubrizol offers a complete family of H₂S scavengers that will enable you to tailor your treatment to achieve maximum efficiency from your applications.


Product Chemistry Solubility Activity Typical pH Description

Performance Highlights

Lubrizol’s water soluble H₂S scavenger products were tested via industry standard test methods. In the included method, a gas mixture of H₂S, CO₂ and nitrogen was bubbled through synthetic brine with the effluent gas continually monitored for H₂S. H₂S scavengers were injected into the brine and the impact to the resulting H₂S was measured. The results reveal scavenging capacity and kinetics under the test conditions. Lubrizol’s SULFA-CLEAR™ 8846 showed an improved total H₂S consumption, capacity and comparable kinetics to MEA Triazine. SULFA-CLEAR™ 8846 is an excellent alternative for MEA Triazine applications. Lubrizol® 6115P presented with the highest total H₂S and is an excellent nitrogen free choice for applications where an extended contact time is possible.
