СО2 & H2S corrosion inhibitor POLY- INCOR® 365 grade 920-B

СО2 and H2S corrosion Inhibitor POLY- INCOR® 365 grade 920-B

TU 2458-112-53501222-2017

Inhibitor POLY-INCOR® 365 grade 920-B is a water soluble corrosion inhibitor, which has been specially developed for the use in oil industry in order to ensure the protection against corrosion due to the presence of CO2 and/or H2S.

POLY-INCOR® 365 grade 920-B is designed for suppressing  of growth of sulfate-reducing bacteria (SRB), for the protection against corrosion and against metal hydrogenation in the processes of oil recovery and transportation, gas recovery and disposal of waste waters containing H2S and CO2.

Customers Benefits
  • High speed of protective film forming.
  • No emulsification is observed.
  • Stability of corrosion inhibitor at high temperature and high pressure.
  • High effectiveness of the inhibitor which allows to reduce the consumption of the chemical at treatment.
  • Compatibility of the inhibitor with other chemicals and materials.
  • Low freezing point of the inhibitor.

Process Technique 

POLY-INCOR® 365 grade 920-B inhibitor is normally injected continuously by a dosing pump.

The injection rate of POLY-INCOR® 365 grade 920-B depends on fluid corrosiveness and is determined with laboratory tests.

For crude oil pipeline transportation systems consumption varies from 10 to 25 ppm, based on total fluid.

When applied in hole annulus of a well equipped with electric centrifugal pump, or for the downhole equipment protection the treatment must be performed periodically once per week or two weeks.

To obtain more detailed information about the chemical, determining its optimal consumption for the particular application or to organize laboratory tests,  please contact the specialists of Sales & Service Department of POLYEX Company. 


POLY-INCOR® 365 grade 021 is delivered in steel drums of 227 dm3 capacity or in PE containers of 1 m3 capacity.

Corrosion inhibitor POLY-INCOR® 365 grade 920-B is certified for the application in oil and gas industry.
