Oilfield & Industrial Applications

Natural Gas Sweetening

Removes H₂S from natural gas streams to meet pipeline specifications (<4 ppm H₂S). Injected upstream of separators or in scavenger contactors.

Sour Crude Oil Treatment

Reduces H₂S vapor pressure in sour crude oil during storage and transportation. Prevents personnel exposure and equipment corrosion.

Produced Water Treatment

Controls dissolved H₂S in produced water before reinjection or disposal. Prevents corrosion in surface equipment and pipelines.

Amine Treating Units

Supplemental H₂S scavenger to protect amine treating systems from H₂S breakthrough during upset conditions.

Tank Vapor Control

Reduces H₂S in tank vapor spaces to protect workers during gauging, sampling, and maintenance operations.

Pipeline Pigging Operations

Batch treatment ahead of pigging operations to reduce H₂S exposure risk and prevent corrosion in pipeline dead legs.
