Determination of Chlorine in Crude Oils and Light Cuts

Abstract

Two methodological variants are developed for determination of the content of organically bound chlorine (OBC) in crude oils and light cuts in quality monitoring in the absence of conditions for implementation of the ASTM D 4929 method. The monitoring scheme is supplemented by the gas –chromatographic method of determining organochlorine compounds (OCC), and “flooding” of carbon tetrachloride into the crude is found. The drawbacks of the ASTM D 4929 method and the advantages of fast determination of the OCC content directly in crudes with the possibility of predicting naphtha quality are demonstrated.
