Corrosion Inhibitors Based on Biogenic Surfactants for Oil And Gas Industry, Environmentally Friendly


Environmentally friendly corrosion inhibitors, based on biogenic surfactants, for anticorrosion protection of equipment and constructions in oil and gas industry. They are synthesized using microorganisms of different genera and can successfully replace synthetic inhibiting substances. The can be used alone and in synergistic compositions with standard inhibitors.

The developed products have economic and environmental benefits. The synergistic anti-corrosion effect resulted from the combined use of biosurfactants and corrosion inhibitors allow the reduction of their concentrations, which assists in inhibiting product cost cut-ting and decrease in environmental impact. Inhibiting biosurfactants can be used at low concentrations due to their high activity and this makes them economically beneficial at price equal to synthetic surfactants. The biogenic inhibitors are characterized by low toxicity and biodegradability. Moreover, in case of entering the soil around oil and gas fields, they can accelerate the natural utilization of various contaminants.

Innovative Aspect and Main Advantages

  • Protection from corrosion and corrosive wear of steel and aluminium alloy drill pipes.
  • Рrotection of equipment for production, transportation and initial separation of oil caused by various inorganic compounds such as stratum water that is found in all crude oils, hydrogen sulfide and hydrogen chloride and other chlorides.
  • Аcid cleaning compositions for tubings and casings.
  • Сorrosion protection of equipment of gas processing plants.
  • Сorrosion protection of oil reservoirs.

The use of new biosurfactant-based inhibitors in different industries

  • For the protection of equipment in chemical industry.
  • For the protection of metal wares from atmospheric corrosion during transportation and storage.
  • In heat-power engineering, particularly in acid cleaning compositions for boilers in electric power stations, in central heating and power plants.
  • To protect lightweight metals in multielectrode systems in liquid cooling systems of internal combustion engines and in cooling systems of electronic equipment.
  • In metallurgy during acid etching of steel pipes and other products and in machine manufacturing when etching wares surface before painting, enameling, galvanic and chemical coatings, before galvanizing.
  • In lubricating fluids for metal working.

When I initially commented I clicked the
"Notify me when new comments are added"
checkbox and now each time a comment is added I get
several e-mails with the same comment. Is there any way you can remove
me from that service? Thanks a lot!
