HCl corrosion inhibitor SOLING grade D

TU 2499-043-53501222-2014

Acid corrosion inhibitor of SOLING grade D is 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 grade D is a blend of surfactants, which is highly soluble in mineral acids.

Application Area

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

  • Protection of black steel equipment meant for acid storage,
  • Protection of oilfield equipment including down-hole equipment.

Customer Benefits
  • Inhibitor SOLING grade D is highly effective in HCl solutions.
  • Inhibitor SOLING grade D is completely soluble in acid, does not spoil the appearance of the acid composition and does not change its color.
  • SOLING grade D reduces interfacial tension between crude oil and acid. It is a very important property for HCl application in oil-producing industry.
  • SOLING grade D eliminates forming of acid-oil emulsions in critical area of formation.
  • SOLING grade D shows prolonged protective effect.
