Determination of the Composition and Concentrations of the Components of Mixtures of Hydrocarbon Media in the Course of its Express Analysis

Abstract

We describe some devices used for the express analysis of the state of environment based on the phenomenon of nuclear magnetic resonance. We propose a new method for the determination of the composition of liquid mixtures of substances that do not participate in chemical reactions with each other. The application of this method enables us to determine the relative concentrations of components of the analyzed mixture. We present the results of investigations of the mixtures of hydrocarbons. The comparison of the numerical and experimental data on the compositions and concentrations of components of the media is performed. The proposed method enables one to determine the contributions of absorption and dispersed signals to the recorded NMR signals of condensed media, which can be either in the stationary state or in the flowing state.
