Extraction and recovery of toxic acidic components from highly acidic oil using ionic liquids
Naphthenic acid (NA) is a toxic compound that exists in the effluent discharged from highly acidic oil refineries. The amount of NA present in acidic crude oil can be as high as 4 wt. The complicated structure of NA poses a challenge for oil refineries in their effort to extract NA from the heavy cr...
