Determination of Physicochemical Properties of Multicomponent Hydrocarbon Systems Based on Integral Characteristics of Electronic Absorption Spectra

A spectroscopic method based on the law correlating the physicochemical properties of substances and their integral electronic radiation absorption characteristics in the visible and/or UV range has been developed for determining the physicochemical properties of various multicomponent hydrocarbon systems. This method can be used for rapid monitoring of hydrocarbon feedstock quality and performance characteristics of oil refining and petrochemical plants.
