HCl Corrosion Inhibitor SOLING grade D

Technical Requirements TU 2499-043-53501222-2014

Purpose of Use

Acid corrosion inhibitors of SOLING brand are designed to provide effective protection of equipment in HCl solutions.

Acid corrosion inhibitor SOLING grade D is meant to provide protection of equipment in synthetic HCl solutions. Application of the inhibitor in more complicated acidic compositions is allowed only after preliminary lab tests.

Acid corrosion inhibitors of SOLING brand  are  blends of surfactants, which are highly soluble in mineral acids.

Application Area

Protection of steel equipment used in chemical, petrochemical and oil-producing industries.

Customer Benefits
  • Inhibitors are highly effective in HCl solutions.
  • Inhibitor is fully soluble in acid, does not spoil the appearance of the acid package and does not change its color.
  • SOLING reduces interfacial tension between crude oil and acid. It is a very important property for HCl application in oil-producing industry.
  • Eliminates forming of acid-oil emulsions in critical area of formation.
  • Prolonged protective effect.
