ABSTRACT:
A more energy-efficient method of processing crude oil is achieved by viscoelastic shearing in order to increase the vapor pressure of the crude oil. This change in vapor pressure allows a more efficient separation of volatile components from non-volatile components in the crude oil. By optimizing the energy expenditure for shearing and the energy expenditure for separating the volatile components from the non-volatile components of the crude oil, while simultaneously removing the volatile components by distillation, one can reduce the overall energy input for the separation. Alternatively, it is possible to affect the distillation at a reduced temperature.
