H2S scavengers

Analyzing Eagle Ford Crude with Lonestar Analyzing Eagle Ford Crude with LonestarThe Eagle Ford Shale Play in Southern Texas is currently (October 2013) the second most productive oil field in the United States, producing some 1.07 million barrels per day . However, after extraction, hazardous levels of hydrogen sulfide may be present in the crude. H2S can be contained or removed with triazine-based scavengers, but leftover scavengers and the reaction byproducts can themselves cause corrosion and fouling downstream. Using the Lonestar portable analyzer, excess scavenger content in crude after treatment can be identified and quantified. For more details, see the Analysis of H2S Scavengers page.
Analysis of Scavengers for Sulfide (H2S) Removal from Crude Oil Analysis of Scavengers for Sulfide (H2S) Removal from Crude OilTriazine compounds are commonly used as scavenger chemicals to remove hydrogen sulfide (H2S) from crude oil, in a process sometimes called "stripping".  These triazine-based additives are often present in excess of the levels required to remove the H2S. The excess triazine, together with the by-products of the scavenging reaction with H2S, may cause corrosion and fouling in downstream equipment. Consequently, there is value in petroleum processors being able to quickly measure excess concentration of scavenger before custody transfer.
