Corrosion inhibitor “HERCULES 40202” is intended for use in the oil industry as a corrosion inhibitor in the production, collection, transportation and treatment of oil. Corrosion inhibitor HERCULES 40201 is a composition based on derivatives of alkylimidazolines in a water-alcohol solvent and is produced in three grades A, B, C, depending on the area and conditions of use in accordance with TU 2458-034-2691334-2016.
Corrosion inhibitor HERCULES 40201 provides reliable protection in highly mineralized environments containing dissolved hydrogen sulfide (grade C) and carbon dioxide (grade A, B).
Corrosion inhibitor HERCULES 40202 has a high sorption activity in relation to metal surfaces.
Used in services
Protection of technological equipment for processing hydrocarbon raw materials
Application
Continuous dosing or periodic treatment at gas wells, wells, at the inlet of oil treatment units, preliminary discharge, reservoir pressure maintenance system.
Dosage
The optimal dosage is established based on the results of pilot industrial tests at the facility.
To achieve the maximum economic effect of using a corrosion inhibitor, preliminary laboratory tests are recommended.
