ABSTRACT:
A process for the distillation and condensation of a multi-component liquid is described, the process being characterized by the utilization of a portion of the condensate in achieving increased separation of components of no-condensed vapor. In a principal embodiment, the overhead from a distillation column is cooled, condensing a portion thereof, and the condensed portion is accumulated in an accumulation zone. A first liquid stream is removed from the accumulation zone for reflux, while a second liquid stream is cooled, and then contacts, in a separate zone, the uncondensed portion of the overhead. The contacting absorbs and condenses components of the vapor, and the second liquid and absorbed components are collected in the accumulation zone.
