1. A method comprising:
removing a process stream from a distillation column;
routing the process stream into a heating medium disposed in a liquid zone of a vessel, the heating medium being less volatile than the process stream, immiscible with the process stream, and maintained at a vaporization operating temperature;
partially vaporizing volatile components of the process stream by thermal exchange with the heating medium in the liquid zone;
removing a vaporized portion of the process stream from a vapor zone of the vessel; and
routing the vaporized portion back to the distillation column.
