Abstract

We studied the influence of the solvent nature on the properties of the asphaltenes isolated from oil by SARA-method. It was calculated spectral coefficients and identified the size of asphaltene particles that have a significant influence on the formation of the deposits in oil and oil products. Determination of asphaltene particle size was carried out on a laser diffractometer «SALD- 7101" with a refractive index of 1.49. It was revealed a connection between the phase stability and the size of asphaltene particles. It was established that heptane asphaltenes are smaller, therefore, the probability of the deposits formation also will be minimal.
