Kurita provides tailored treatment concepts for refinery applications

Corrosion inhibitors ensure economic benefits.

Corrosion attack is an omnipresent threat in oil refineries, which may result in reduced production, cost of maintenance and repairs. The replacement cost for equipment, safety aspects and potential environmental issues can lead to significant economical losses.
Due to its low purchase costs carbon steel is often used to manufacturer distillation equipment. Carbon steel is very unstable in acids and corrosion rates increase sharply when pH drops down below 7. Corrosive components such as hydrogen chloride (HCl), hydrogen sulfide (H2S), ammonium chloride (NH4Cl), ammonium bisulfide (NH4HS), carbon dioxide (CO2) and organic acids damage the process equipment. 

Typical corrosion forms in refineries are, in particular:

  • Local corrosion or Pitting
  • Hydrogen Induced Corrosion (HIC)
  • Stress Corrosion Cracking (SCC)
  • Erosion
  • Cavitation

Corrosion is an electro-chemical process which can be clearly reduced or even avoided by corrosion inhibitors. Kurita provides very powerful treatment programs which are adapted to the specific requirements of your processes – in favor of a safe corrosion protection.

Besides the selection of suitable neutralizing amines or filming amines the determination of the pH-condensation profile and water dew point plays a decisive role in a successful treatment. Using a specially developed calculation program we are able to identify exactly these parameters.
