Measurement Of The Refractive Index Of Crude Oil And Asphaltene Options: Onset Flocculation Dedication
In this work, we measure the refractive index of crude oils and asphaltene in toluene options using a fiber optic refractometer designed to work with excessive-viscosity and excessive optical Chemical Project Package Installation density samples. The information of the samples had been analyzed utilizing the Lorentz−Lorenz theory and easy mixing guidelines. The refractive index for crude oils with out dilution for three crude oils with different American Petroleum Institute (API) diploma, asphaltene quantity, and stability had been measured. Flocculation onset for crude oils and asphaltene options were measured using n-heptane as the precipitant agent. Results confirmed that medium crude oils and maltenes from medium, heavy, and further-heavy crude oils observe the Lorentz−Lorenz mixing rule. Within the case of Boscan crude oil, a pattern with none significant asphaltene precipitation issues, the refractive index is irving oil prices lower than that obtained for toluene. In contrast, Furrial crude oil, a sample with extreme asphaltene precipitation problems, gave a refractive index greater than toluene. Finally, asphaltene flocculation onset was clearly adopted by refractive index measurement in crude oils and asphaltene in toluene solutions after n-heptane addition.
