Sulfide Scavenger Chemistry for Liquid & Vapor Treatment

Sulfide scavenging involves the removal of dissolved sulfide ions (HS- and S2-) and free hydrogen sulfide from water streams. Dissolved sulfides promote microbiologically influenced corrosion (MIC) by supporting sulfate-reducing bacteria (SRB).

Controlling Dissolved Sulfides in Process Waters

Sulfide ions in produced water and industrial wastewater generate highly corrosive acids. Injecting high-affinity triazines converts dissolved sulfides into non-volatile, stable dithiazine molecules, protecting steel infrastructure.

Frequently asked questions

What is the difference between vapor scavenging and liquid scavenging?+
Vapor scavenging extracts gas-phase H2S from gas streams using spray contactors or bubble towers. Liquid scavenging treats dissolved sulfides directly in liquids like crude oil, fuel oil, or wastewater.
What is the typical pH range of spent triazines?+
Spent triazines are alkaline, usually displaying a pH range between 9.0 and 11.5, which helps prevent sour gas reactivation but requires careful waste management.
