Key words: asphalt-resin-paraffin deposits, oil wells, extraction, propane, butane, phase equilibrium, supercritical fluid

The results of an experimental study of the characteristics of phase equilibria for the systems «hexadecane — propane/butane» and «sulfur — propane/butane» are presented. The data on the kinetics of extraction of hydrocarbons from asphalt-resin-paraffin deposits are presented. It has been established that it is preferable to use the SCFextraction process (as opposed to the liquid one) in relation to the process of cleaning the wellhead of oil wells from asphalt-resin-paraffin deposits.
