The results show that propane has a strong heavy oil extraction capacity and that the solubility of propane in the oil and density and viscosity of the oil depend on pressure. It is shown by gas chromatography and IR spectroscopy that the composition of the oil changes during the propane extraction process: the content of light components increases and the content of heavy components decreases due to deasphalting.
