Abstract

The structural-group composition of natural petroleum emulsifying agents was studied. It is shown that an increase in water content in emulsions causes a substantial increase in the fraction of pyrobitumen in the interfacial layer and a decrease in the concentration of tarry components. It was established that among n- alkanes of the interfacial layers of emulsions with demineralized and oil field water, the fraction of low- and high molecular mass n- alkanes increases.
