WF-CY10 Oilfield-Specific Oxygen Scavenger

1. Product description
WF-CY10 Oilfield-Specific Oxygen Scavenger is a reductive aqueous solution. Its core active ingredient is special sodium salt, compounded with stabilizers and corrosion inhibitor additives. This product rapidly undergoes irreversible reduction reactions with dissolved oxygen in formation
produced water and reinjection water to eliminate dissolved oxygen in water, thereby inhibiting oxygen corrosion of pipelines, downhole tubulars and storage tanks. It is applicable to oilfield water injection, gathering and transmission pipelines, produced water reinjection and downhole operation
fluid systems. Featuring high salinity tolerance, medium-low temperature resistance and excellent compatibility, it can be dosed simultaneously with scale inhibitors, biocides and corrosion inhibitors.
2. Product Characteristics
Long-lasting stable oxygen removal; fast reaction rate with catalyst, suitable for oilfield wastewater with high salinity under both high and low temperature conditions
Neutral system, non-corrosive to carbon steel, FRP and PE pipelines, and causes no damage to metering pump equipment
Liquid formulation with excellent water solubility; no precipitation, no formation or water injection pipeline blockage
Excellent compatibility; can be added simultaneously with organic scale inhibitors, non-oxidizing biocides and corrosion inhibitors
3. Physical property data
Indexes Properties
Appearance Pale yellow transparent homogeneous liquid
pH value (126g/L solution) 5-7
Solubility Soluble in alcohol, dispersible in water
Active content 35-55%
Density (g/cm³，25℃) 1.18～1.38
4. Method of application
Dosing Points: Incoming pipelines of oilfield water injection stations, front ends of gathering pipelines, wastewater reinjection pipelines and liquid mixing tanks.
Dosing Method: Continuous quantitative dosing via metering pumps; intermittent shock dosing is applicable to small oilfield blocks.
Recommended Dosage: Dose 6–9 ppm of this product per 1 ppm dissolved oxygen. The routine dosage for general oilfield wastewater is 0.005%–0.08%, which can be increased to 0.2% for produced water with high oxygen content. Fine-tune the dosage according to on-site dissolved
oxygen test data during application.
