WF-CY20 high-efficiency oxygen scavenger

1. Product description
WF-CY20 is an aqueous high-efficiency oxygen scavenger dedicated to oilfields, with carbohydrazide as the primary active ingredient, compounded with metal passivation additives and water quality stabilizers.
Featuring strong reducibility, this product rapidly reacts with dissolved oxygen present in oilfield reinjection water, produced water, gathering pipeline fluid and boiler feed water, generating nitrogen, carbon dioxide and water without secondary corrosive by-products. It also delivers metal passivation
performance by forming a protective film on carbon steel inner walls to inhibit oxygen corrosion. It is compatible with oilfield wastewater under high/low temperature and high salinity conditions.
2. Product Characteristics
? High oxygen removal efficiency with complete reaction; provides dual functions of metal passivation and corrosion inhibition for pipeline metals
? Liquid formulation with excellent water solubility, no precipitation, and no blockage to formations and chemical dosing pipelines
? Mild neutral system, free from strong acidity and high corrosivity, resulting in low equipment wear
? Outstanding compatibility; can be dosed simultaneously with organic scale inhibitors, non-oxidizing biocides and corrosion inhibitors
3. Physical property data
Indexes Properties
Appearance Colorless to pale yellow liquid
pH Value (Neat Solution) 7-9
Active Content (%): 5–30
Density (g/cm³, 25°C): 1.05–1.18

4. Method of application
Dosing Points: Front sections of incoming pipelines at water injection stations, wastewater reinjection pipelines, main gathering pipelines, chemical mixing buffer tanks and boiler feed water pipelines.
Dosing Method: Continuous fixed-quantity dosing via metering pumps; intermittent shock dosing is acceptable for small oilfield blocks.
Recommended Dosage: Add 25–35 ppm of the product per 1 ppm dissolved oxygen. The routine dosage for ordinary oilfield wastewater ranges from 0.008% to 0.10%, and the maximum dosage can reach 0.15% for high-oxygen produced water. Adjust the dosage properly based on on-site dissolved oxygen test results.
5. Packaging, storage and precautions
Packaging Specifications: 25kg PE plastic drums, 200kg plastic drums, 1000kg IBC totes; customized packaging is available upon negotiation.
Storage Conditions: Store hermetically sealed away from light in cool and ventilated warehouses at an ambient temperature of 5–30°C, far from heat sources and direct sunlight. Keep separate from strong acids and oxidizing chemicals by partition.
