Case No. 6204 HEAT PUMP FRACTIONATION PROCESS Abstract of the Disclosure A process for fractionating two or more com- pounds in which the stripping section of the fraction- ator is maintained at a first pressure and the recti- fying section of the fractionator is maintained at a higher pressure. Overhead vapors from the stripping section are compressed in a heat pump where the vapor temperature and pressure are raised, and the heated and compressed vapors are then fed to the bottom of the rectifying section. Overhead vapors from the rectifying section, at a higher temperature than the bottoms from the stripping section, are heat exchanged with stripping section bottoms to condense overhead vapors and to supply reboiling heat to the stripping section.
