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.

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.
