WF-HQ550 Vapor Phase Corrosion Inhibitor

1. Product description
WF-HQ550 Vapor Phase Corrosion Inhibitor is mainly composed of low-boiling heterocyclic amides with good dispersibility in both gas and liquid phases. It provides excellent anti-corrosion performance against comprehensive gas-liquid two-phase corrosion caused by H?S and the liquid-phase H?S-H?O system formed by dissolved hydrogen sulfide in water. With effective chemical concentration maintained, the corrosion inhibition rate can reach ? 95%, and localized corrosion can be effectively controlled. This product is especially suitable for corrosion protection of water and high H ?S-containing natural gas gathering and transmission trunk lines, compressor stations, and oil and gas wells.

4. Method of application
WF-HQ550 Vapor Phase Corrosion Inhibitor is generally diluted with low-carbon alcohols, then injected into pipeline systems via metering pumps or directly added to gas well casings. The dosage shall be adjusted according to on-site H?S concentration and corrosion severity. Normally, 200~500 ppm of this gas corrosion inhibitor is dosed based on the condensate water content in natural gas. For newly commissioned gathering transmission and wastewater treatment systems, pre-filming treatment is required at a pre-filming concentration of 500 mg/L.
