Abstract
A process for the direct contact heating and vaporization of UMO is disclosed. A superheated, but condensable, vapor heats and vaporizes distillable liquid hydrocarbons from a waste motor oil stream, producing an overhead vapor fraction of injected superheated vapor and vaporized boiling range components. This material is cooled and partially condensed to produce lube boiling range liquid hydrocarbons and a vapor phase, which is condensed to produce a recycle liquid phase. Recycle liquid is pumped and then heated to produce superheated vapor for recycle to contact the UMO.
