  • Method of Screening Crude Oil for Low Molecular Weight Naphthenic Acids
    Publication number: 20070298505
    Abstract: A method for the quantitation of the naphthenic acid content of molecular weight less than 600 Daltons in a hydrocarbon composition, in which naphthenic acids are separated from the hydrocarbon composition and applied to a macroreticular ion-exchange resin. The resin is washed and the naphthenic acid-metal ion complexes are eluted from the resin. The number of naphthenic acid-metal ion complexes present in the eluate from the resin are then quantitated.
