TU 2499-043-53501222-2014

Acid corrosion inhibitor of SOLING grade LU is designed to provide effective protection of equipment in HCl solutions.

Acid corrosion inhibitor SOLING grade LU  is meant for the effective protection of equipment in HCl solutions, hydrofluoric acid solutions and their blends.

Acid corrosion inhibitor  SOLING grade LU 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 is highly effective in HCl and hydrofluoric acid solution blends. Steel corrosion in the stated mediums makes 0.2 g/m2∙hour with working concentration of  SOLING grade LU inhibitor of about 0.2 - 0.4%.
  • Inhibitor is completely soluble in acid, does not spoil the appearance of the acid compositions and does not change their color.
  • SOLING grade LU reduces interfacial tension between crude oil and acid. It is a very important property for HCl application in oil-producing industry.
  • SOLING grade LU eliminates forming of acid-oil emulsions in critical area of formation.
The inhibitor provides prolonged protective effect.
