Corrosion Inhibitors

CORROSION INHIBITORS

Corrosion is one of the main culprits of the Oil & Gas Industry. Corrosion is defined as a gradual destruction of a material or substance.  It is the main cause of equipment and pipeline leaks, which triggers substantial damages to our clients`operations. Wherever they occur, leaks have a substantial cost impact on refiners and operators, leading to significant loss of production, maintenance, clean-up and remediation requirements. 

Corrosion rates increase dramatically when pH drops below 7. Some corrosive agents are: Hydrogen Chloride, Hydrogen Sulfide, Ammonium Chloride, Ammonium Bisulfide, Carbon Dioxide and Organic Acids.

Corrosion in refineries takes various paths:
  • Local corrosion or Pitting
  • Hydrogen Induced Corrosion (HIC)
  • Stress Corrosion Cracking (SCC)
  • Erosion
  • Cavitation
A CORROSION INHIBITOR is a chemical compound that, when added to a liquid or gas, decreases the corrosion rate of a material, typically a metal or an alloy. These inhibitors adhere to the metal surface to form a hydrophobic barrier film between the metal and the fuel. A common mechanism for inhibiting corrosion involves formation of a coating, often a passivation layer, which prevents access of the corrosive substance to the metal.

Effective CORROSION INHIBITOR additives are designed to protect against following issues:
  • Storage vessel and pipeline leakage
  • Fuel contamination with particulates
  • Blockage of filters and screens from corrosion particulates
  • The requirement for expensive maintenance.
