General
Corrosion inhibitor for injection water ZX-C2-01 is a corrosion inhibitor compounded from complex pyridine quaternary ammonium salts. It can be used to prevent corrosion of oil pipes, equipment, etc. caused by the reinjection of oilfield wastewater and produced water containing high concentrations of acidic gases and high mineralization salts. It especially has a good protective effect on hydrogen embrittlement and pitting corrosion caused by corrosive media such as H2S and CO2 systems, and can effectively protect the metal substrate from damage. To achieve the purpose of extending the service life of the pipeline. It has a high corrosion inhibition efficiency, capable of reducing the corrosion rate of carbon steel to below 0.076mm/a, with a corrosion inhibition rate as high as 80% or more, and the product is stable. is a kind of water solubility film formation corrosion inhibitor, which is composed of home-grown composite pyridine quaternary ammonium salt as main ingredients, other synergist and surfactant. Non-polar groups in the molecule can effectively prevent CO2, H2S corrosion medium from metal local corrosion. And while the hydrophilic groups are firmly adsorbed on the metal surface and form a dense protective film. So it can keep a long time for metal against corrosion. It has a good protection, especially for hydrogen embrittlement and pitting which are produced by high concentrations of CO2 system. Also, it has a good anti-corrosion for H2S local corrosion. The product has good heat stability and chemical stability.

To achieve the purpose of extending the service life of the pipeline. It has a high corrosion inhibition efficiency, capable of reducing the corrosion rate of carbon steel to below 0.076mm/a, with a corrosion inhibition rate as high as 80% or more, and the product is stable.t is application for protecting oilfield water injecting pipeline corrosion and equipment corrosion. It has a good protection function for not more that 20% CO2, H2S and other acid gases, as well as not more than 200000 mg/L salinity saltwater corrosion environment.
Instructions
Calculated by liquid production capacity, generally add 50ppm. Appropriately increase amount for the severe corrosion area. The corrosion rate can reach more than 80%. As for the high salinity area, dilute by tap water to 10-20%, and then add it.
Product characteristic
Obviously corrosion inhibition properties effect on CO2, H2S and resistance to high salinity

Safety and handling
Skin Exposure:
In case of contact, immediately wash skin with soap and copious amounts of water. If irritation persists, call a physician.
Eye Exposure:
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers.
If irritation persists, call a physician.
Inhalation Exposure:
If inhaled, remove to fresh air. If necessary, give oxygen. Call a physician.
Oral Exposure:
If swallowed, immediately wash out mouth with water provided person is conscious. Call a physician.
