Acidic constituents of heavy California crudes cause corrosion in the processing equipment. Many of the smaller acids have been identified, and this paper will focus on the heavier acidic compounds from a San Joaquin Valley crude. The acidic fraction is isolated by base extraction, methylated and analyzed by desorption high resolution mass spectrometry, NMR, and FTIR. The majority of the compound groups have been identified. The effect of mild hydrotreating on the distribution of acidic components will be discussed.
