Corrosion inhibitor-bactericide NAPOR-1004 Brand R
Purpose and scope of application
NAPOR-1004 Brand R
NAPOR-1004-R is a specific grade of the NAPOR-1004 corrosion inhibitor and bactericide, based on a water-soluble cationic surfactant. It is designed to inhibit sulfate-reducing bacteria (SRB) and protect equipment against corrosion and metal hydrogen embrittlement during oil and gas extraction and transport, as well as during the handling of wastewater containing hydrogen sulfide and carbon dioxide.
It is applied via continuous dosing into oil-water emulsions or through periodic injection into production wells. At a concentration of 15–30 g/m³ in the oil gathering system, it helps reduce the viscosity of oil-water emulsions (by up to 85%), which can lead to lower internal pipeline pressure during transport.
To suppress SRB populations, shock treatments in the range of 50–200 g/m³ are used, depending on the degree of contamination and the culture's resistance. In a standard solution of hydrogen sulfide-containing wastewater, it provides a protective effect of at least 90% at a dosage of 20 mg/dm³.
The "R" grade is characterized by an elevated amine value (100 mg HClO₄/g), an active ingredient mass fraction of 20% (±10%), and a phosphorus mass fraction of 2.0% (±10%). The pH range of a 1% aqueous solution is 7.0–10.0. The pour point is no higher than −40°C (for the Ural-Volga and Southern regions) and no higher than −50°C (for the Siberian region). It does not adversely affect oil refining processes or the quality of commercial crude oil. It exhibits synergism with a number of demulsifiers.
It is manufactured in accordance with TU 2458-011-12966038-2001.

FAQ
What is distinctive about the NAPOR-1004-R model?
For planktonic forms of SRB, the specific consumption rate is 50–100 mg/dm³, while for adherent forms, it is no more than 400 mg/dm³. Specific values depend on the degree of contamination of the facility.
What flow rate is used to suppress a spontaneous gas blowout?
This grade is characterized by a high amine value (100 mg HClO₄/g) and an active ingredient content of 20%, factors that are taken into account when determining dosage and application conditions.
NAPOR-1004-R has no adverse effect on oil refining or the quality of commercial oil.
Does the reagent affect oil treatment processes?
At a concentration of 15–30 g/m³, a reduction in the viscosity of water-in-oil emulsions (by up to 85%) is possible, which can help lower in-pipe pressure.
What effect is achieved by dosing into the oil gathering system?
