Sulfa-Clear 8411C


Sulfa-Clear® 8411C is a patented 59% active aqueous amine resin solution designed as a sulfide scavenger for water. Sulfa-Clear® 8411C can also be used as an additive to water-soluble corrosion inhibitors and surfactants to enhance control of micro-organisms.


Hydrogen Sulfide is a poisonous gas that is deadly at high concentrations and provides serious health-threats at moderate concentrations. Operating problems caused by H2S can include severe corrosion and fouling, and injection well plugging with iron sulfides, Sulfa-Clear® 8411C can be injected continuously into water gathering lines, water tanks, holding pits, and vapor overheads. It can be diluted with methanol or water for application purposes. Sulfa-Clear® 8411C solutions containing converted sulfide are water-soluble surfactants that are normally injected into water disposal systems.

  • Fast, effective sulfide removal
  • Produces water-soluble surfactant solutions
  • Enhances control of micro-organisms
  • Can be used in water, gas or crude oil


The amount of Sulfa-Clear® 8411C required depends upon the level of H2S in the system and the degree of reduction desired.

In water systems, the scavenging rate of Sulfa-Clear®8411C is 2.0 to 20.0 ppm per ppm sulfide. For treatment of H2S in gas or crude oil, Sulfa-Clear®8411C can be used at concentrations of 1 to 10ppm per ppm H2S.
