ABSTRACT:
Improved crude oil processing is achieved by viscoelastic shearing of crude oil at an elevated temperature. The shearing provides for an enriched light fraction and an enriched heavy fraction that can be more efficiently separated by distillation. Shearing is achieved using a mobile surface and immobile surface, or other flow geometry, under conditions providing for a transient phase separation.
