Sulfa-Clear 8640 Hydrogen Sulfide Scavenger

SULFA-CLEAR 8640 is a patented 60-65% active aqueous amine resin solution containing surfactants designed as a hydrogen sulfide scavenger for gas systems. SULFA-CLEAR 8640 can also be used as an additive to corrosion inhibitors and surfactants to enhance control of microorganisims.


Continuously inject into gas gathering lines, transmission lines, vapor overheads, water gathering lines, water tanks, or holding pits.
Can be diluted with methanol, glycols, or water for application purposes.
Can be used as a replacement for amine sweeting solutions and ironite sponge systems in a batch treatment.
Reacted solutions are water-soluble, functioning as a corrosion inhibitor, and normally injected into water disposal systems.

Features, Advantages and Benefits

Fast, effective sulfide removal.
Used in gas and water applications.
Performs in a variety of line applications.
Produces water-soluble solutions.
Enhances control of microorganisms.


The amount of Sulfa-Clear 8640 required depends upon the level of H2S in the system and the degree of reduction desired. The typical ratio is 4.0 ppm Sulfa-Clear 8640 per ppm H2S.

In gas systems, the scavenging rate of is 1.0-1.5 ppm per ppm gallons per MMSCF of gas per ppm H2S.

For traeting H2S in gas, one gallon of Sulfa-Clear 8640 removes 2.21 pounds of H2S.
