Application of PARAFAC Method in Petroleum Organic Measurement and Analysis

Abstract

The analysis algorithm of parallel factor, combined with fluorescence spectroscopy of three dimensions are used to study the organics identification in petroleum for impurities in surface water and concentration measurement, analysizing the effects on measurement of the coexist of multi-component petroleum pollutants. Treating gasoline, kerosene and diesel as samples, through a mixed solution of a variety of different proportions to imitate the state of coexistence of a variety of petroleum organic, studying PARAFAC in a variety of characteristics of the mixed solution component. Experiment focused on the Steam diesel hybrid solution, Wood kerosene mixed solution and Steam wood kerosene mixed solution, and it can separate their different fluorescence spectrums from the complex mixed composition of three dimensional fluorescence spectrum data matrix. It realized the simultaneous measurement for the main factor in composite samples. And it also calculates the average error rate of concentration .The result indicates that PARAFAC can realize petroleum pollutants composite sample identification and concentration measurement.
