Corrosion inhibitors (СО₂)

The corrosion inhibitor «Defence»

The corrosion inhibitor «Defence» is designed to protect the oil and gas field equipment from corrosion in environments, containing the carbon dioxide (CO₂)

In the stream of highly mineralized water a level of protection against corrosion damage exceeds 90%.

Parameters:
Outer appearance - liquid from light brown to dark brown color.
Density at 20° C in the range of 0.925 g / cm 3.
Viscosity by Angler at 20° C, Angler degrees - 5.0. Solidification temperature is not higher - minus 15° C.
Acid number, mg KOH per 1 g of the product, not less than - 9.4. pH value (1% aqueous solution) - 6.3.
Aftereffect - more than 90 days.
Protective action.
Determination results of the «Defence» corrosion inhibitor protective action are shown in table 1.

The «Defence» corrosion inhibitor is totally soluble in hydrocarbon condensates of paraffinic and paraffin-aromatic type, is not soluble in water, does not produce a stable emulsion in a twophase system «дhydrocarbon condensate - mineralized water» in a ratio of 1:4.

According to the degree of impact on the human body it relates to 4-class low-hazard substance. It is supplied in drums and railway tanks.

The «Defence» corrosion inhibitor is most suitable for use on well bores of deposits with carbon dioxide aggressiveness of environment and low gas condensate factor.

Taking into account the inhibitor low cost and its excellent operational characteristics, the given proposal is the most profitable in today's market of corrosion inhibitors.

 The corrosion inhibitor «Unicor-3»

The corrosion inhibitor «Unicor-3» is innovative additive for mineral oils, which is designed to protect the oil and gas field equipment from corrosion in environments containing carbon dioxide (CO2).
In the stream of highly mineralized water a level of protection against corrosion damage exceeds 90%. In such a case, effect is achieved with minimum rates of the inhibitor during use.

Parameters:
Outer appearance - liquid of dark brown color.
Density at 20° C in the range of 0.925 g / cm 3.
Viscosity by Angler at 20° C, Angler degrees - 5.0.
Solidification temperature is not higher - minus 19° С.
Acid number, mg KOH per 1 g of the product, not less than – 9,4.
pH value (1% aqueous solution) – 6, 3.
Aftereffect - more than 90 days.
Protective action.
Determination results of the «Unicor-3» corrosion inhibitor protective action are shown in table 2.

The «Unicor-3» corrosion inhibitor is soluble in mineral oils, aromatic hydrocarbons, insoluble in water, does not produce a stable emulsion in a two-phase system «hydrocarbon condensate mineralized water».

It has a long aftereffect.


High-performance protection of tube steel P-105 is achieved as late as using a 10%  solution  of the inhibitor (Z = 96, 4%).

According to the degree of impact on the human body it relates to 4-class (a low-hazard substance). It is supplied in drums and railway tanks.
The «Unicor-3» corrosion inhibitor is most suitable for use on well of deposits with carbon dioxide aggressiveness of environment and low gas condensate factor. This product is characterized by its high efficiency at low consumption rate during use.
