Abstract

Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.
