Triazine

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.
