This work investigated the distribution of the chlorine element in Shengli (SL) crude oil using a microcoulomb titrameter and a salt content determinator. The species and contents of organic chlorides in light distillates (bp < 300 °C) were determined by gas chromatography equipped with an electron capture detector (GC–ECD). The content of organic chloride in SL crude oil was 188.68 mg/L, and organochlorine compounds were found in each distillate of SL crude oil. The contents of organochlorine in naphtha, kerosene, and light diesel were measured as 302.93, 729.45, and 836.90 mg/L, respectively. The species of organic chlorides that existed in naphtha, kerosene, and light diesel were similar. Trichloroethylene, 3-chloro-2-methylaniline, 5-chloro-2-methylaniline, and 2,6-dichloro-3-methylaniline were all identified in the three types of light distillates of SL crude oil. The gas chromatography quantitative analysis results of organic chlorides in light distillates (bp < 300 °C) illustrated that a large proportion of organic chlorides has been identified, in which 5-chloro-2-methylaniline was the dominate species.
