Corrosion inhibitor “Para 40202” is intended for use in the oil industry as a corrosion inhibitor in the production, collection, transport and treatment of oil. The Para 40201 corrosion inhibitor is a composition based on alkylimidazoline derivatives 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 Para 40201 provides reliable protection in highly mineralized environments containing dissolved hydrogen sulfide (grade C) and carbon dioxide (grades A, B).
Corrosion inhibitor Para 40202 has a high sorption activity in relation to metal surfaces.
Used in services
Protection of technological equipment for the processing of hydrocarbon raw materials
Application
Continuous dosing or intermittent treatment at GZU, wells, at the inlet of oil treatment plants, preliminary discharge, pressure maintenance system.
Dosage
The optimal dosage is established according to the results of pilot tests at the facility.
To achieve the maximum economic effect of using a corrosion inhibitor, preliminary laboratory tests are recommended.
