Specialty Hydrogen Sulfide Scavenger Chemistry

Sour gas and sour crude contain hydrogen sulfide (H2S), which poses immediate occupational risks and environmental hazards. Applying a chemical hydrogen sulfide scavenger reduces vapor-phase H2S to zero ppm, enabling safe transportation and refining.

The Hazards of Sour Hydrocarbon Streams

Acidic H2S gas initiates micro-cracking and pits metal surfaces when dissolved in water. Dosing high-performance organic scavengers removes the gas from both the gas and liquid phases, neutralizing acid gases and eliminating toxic vapor emissions.

Direct Contact Tower Applications

For high-volume sour gas sweetening, direct contact towers utilizing a diluted batch of MEA Triazine 78% provide the highest mass-transfer efficiency, scrubbing sulfur compounds out of the gas stream down to pipeline specifications (usually under 4 ppm).

Frequently asked questions

How is the scavenger dosage calculated?+
Dosage depends on the H2S concentration (ppm), gas flow rate, temperature, and target outlet specification. Typically, 1 to 4 ppm of active triazine chemical is required per ppm of H2S removed.
What is the shelf life of your liquid H2S scavengers?+
Under proper storage conditions (cool, dry, ventilated area), our liquid triazine based scavengers maintain a stable shelf life of 12 to 24 months.
