Abstract
The study examines the existing asphaltene flocculation inhibitors in oil dispersed systems — oil-soluble surfactants of various nature. It is proposed to use cheap surfactants of vegetable origin as flocculation inhibitors — phosphatide concentrate and sodium sulfosuccinate. The process of flocculation of asphaltenes on model mixtures of asphaltenes of different concentrations with toluene and precipitants, as well as the influence of the proposed inhibitors on the aggregative stability of the mixtures, was studied. The flocculation starting point (onset point) of each mixture was determined by the photocolorimetric method.
