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.
