RESEARCH OF QUASI-THERMODYNAMIC PARAMETERS OF VISCOUS FLOW ACTIVATION OF MULTICOMPONENT HYDROCARBON SYSTEMS
A serious problem in modern oil industry is the increase of heavy oil recovery, which contains a significant amount of impurities (asphaltenes, sulfur, metals). The physical and chemical properties of Yarega heavy oil and its atmospheric residue are presented. Based on the studies of structural and mechanical properties of oil and atmospheric residue, it was determined the free energy, enthalpy and entropy of activation of a viscous flow, as well as the dependence of the hopping frequency of molecules on temperature.
