Where Is Naphthenic Found?

Naphthenic acids (NAs) are widely present in crude oil and oil sands process-affected water (OSPW). NAs in crude oil lead to corrosion problems, promote emulsion formation, decrease oil quality, and deactivate catalysts, making it critical to isolate NAs.

Where is naphthenic acid found?

Naphthenic acids are the major contaminant in water produced from the extraction of oil from Athabasca oil sands (AOS). Naphthenic acids have both acute and chronic toxicity to fish and other organisms.

What is naphthenic acid used for?

The major uses of naphthenic acids are as oil-soluble metal soaps for driers and other catalysts, wood preservatives, tire cord adhesion promoters, and in amine derivatives for corrosion inhibitors.
