摘要: Abstract A Model emulsion (water/(heptane-toluene)) phase inversion process induced by changing salt concentration and crude oil emulsions processes alteration of water-oil ratio (catastrophic), temperature surfactant were monitored NIR spectroscopy electrical conductivity. spectra treated Principal Component Analysis the results showed that this technique can be successfully applied to identify inversion, in particular complex systems such as where collected during very similar with a narrow range formulation variable. Furthermore, was also able detect dispersion transition plots first principal component conductivity provided much better picture than single measurement plots.
