Project at a Glance Contents on the CD ROM
  • A complex of carboxylic acids obtained from different distillation fractions of crude oil like gas oil, kerosene or light lubricating oils.
  • Acids are by-products of petroleum refining.
  • A continuous process has been developed for removing Naphthenic acids from refinery streams by caustic washing.
  • Free Naphthenic acids are corrosive and are mainly used as their salts and esters.
  • For example, calcium naphthenate is a lubricating oil additive, and zinc naphthenate is an antioxidant. Lead, zinc, and barium naphthenates are wetting agents used as dispersion agents for paints.
  • Some oil soluble metal naphthenates, such as those of zinc, cobalt, and lead, are used as driers in oil-based paints.
  • Naphthenic Acid Corrosion is characterized by deep pitting and metal impingement.
  • Naphthenic Acid with a lower acid value can replace stearic acid in certain rubber compounds, e.g.: tyre thread and conveyer belt.
  • It can be used as flotation agents in the recovery of the 'non sulphide' types of ores.
  • Naphthenic Acid 170 DE is suitable as an additive to lubricants.
  • Naphthenic acid is a dark colored liquid with an offensive odor and acid is also insoluble in water.
  • These Acids are classified as monobasic carboxylic acids.
  • Commercial production of Naphthenic acid from petroleum is based on formation of sodium naphthenates when the petroleum distillated are treated with sodium hydroxide caustic. Since this reaction occurs, sodium salts is considered an intermediate stream in the production of Naphthenic acid.
  • Petroleum industry uses Naphthenic acid amine derivatives as surfactants for enhanced oil recovery and as corrosion inhibitors for refineries, pipelines and down hole use.
  • Acids are found in wastewaters from petroleum refineries and oil sands extraction plants.
  • When high acid values are required for synthesis of high metal content soaps it is recommended to upgrade the acids with some synthetic ores.
  • Found applications in several industries such as drying agent ,wood preservation, synthetic detergents, additive to fuels, corrosion inhibitor and plasticizer in the production of polyvinyl-chloride and rubber products.
