OBTAINING A CORROSION INHIBITOR BASED ON VEGETABLE OILS

The destruction of petrochemical production equipment caused by acid corrosion is one of the main environmental problems the oil refining industry is facing with. Metal corrosion, including corrosive destruction of metal structures: pipelines, tanks, reactors and so on, can cause their functionality decrease, as well as emergency situations with spills of aggressive and biologically hazardous liquids and gases, which will lead to a local increase in environmental pollution. A promising method to protect structural steel from acid corrosion is the use of corrosion inhibitors. The paper considers the impact of corrosion effects on environmental pollution. A corrosion inhibitor based on fatty acids obtained from rapeseed and sunflower oils and monoethanolamine, diethanolamine was obtained. The anticorrosive properties of the obtained substances are investigated.
