СО2 и H2S Corrosion Inhibitor NORUST®9805

Technical Requirements TU 2458-083-53501222-2011

NORUST® 9805 is a water soluble film-forming corrosion inhibitor which has been specially designed for use in oil industry in order to ensure a protection against corrosion induced by the presence of CO2 and/or H2S.

Two grades of NORUST® 9805 are available: NORUST® 9805 grade A and NORUST® 9805 grade V.

Application Area

  • Protection of gas condensate and oil wells from CO2 and/or H2S corrosion.
  • Protection of oil collection systems from CO2 and/or H2S corrosion.
  • Protection of oil field equipment from CO2 and/or H2S corrosion.

Customer Benefits

  • High speed of protective film forming.
  • No emulsification is observed. No influence at oil treatment.
  • Stability of corrosion inhibitor at high temperature and high pressure.
  • Because of NORUST® 9805 special formulation it doesn’t form foam.
  • High effectiveness of the inhibitor which allows to reduce the chemical consumption at treatment.
  • Compatibility of the inhibitor with other chemicals and materials.
  • Low freezing-point of the inhibitor.

Process Technique

NORUST® 9805 is normally injected continuously by means of a dosing pump.

The injection rate of NORUST® 9805 depends on fluid corrosivity. For crude oil systems the consumption varies between 10 to 30 ppm based on total fluid.

For gas pipeline systems the consumption varies between 10 to 50 liters per million of cubic meters of gas.

To select the optimal design of application and consumption of H2S & CO2 corrosion inhibitor NORUST® 9805 it is recommended to contact the specialists of Polyex company.

Corrosion inhibitor NORUST® 9805  is certified for the application in oil and gas industry.

H2S & CO2 corrosion inhibitor NORUST® 9805 is produced according to the technology and from the materials provided by the company of ARKEMA / CECA, France, under license.
