Influence of Microwave Processing of Heavy Stock Oil on Oil Fluidity

The effect of heavy stock oil heating by ultra-high frequency (microwave) electromagnetic field on oil viscosity changes is investigated in the present work. The influence of the phase state of supramolecular formations on the rheological properties of heavy oil after the application of various dielectric heating schemes is studied. The energy of the intermolecular interaction of asphaltene nanoaggregates of various sizes is estimated based on rheometric studies of heavy oil treated with microwave energy. It has been established that for a stable asphaltene oil, the hybrid microwave processing scheme is most effective.
