IMPROVED SEPARATION OF COMPLEX MIXTURES

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 immo...

Beschreibung
Zusammenfassung:	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. Selon l'invention, le traitement amélioré de pétrole brut est obtenu par cisaillement viscoélastique de pétrole brut à une température élevée. Le cisaillement permet d'obtenir une fraction légère enrichie et une fraction lourde enrichie qui peuvent être séparées de manière plus efficace par distillation. Le cisaillement est obtenu au moyen d'une surface mobile et d'une surface immobile, ou d'une autre géométrie d'écoulement, dans des conditions permettant d'obtenir une séparation de phase transitoire.
