Abstract

A method and apparatus for transferring a first liquid removed from an outlet of a first distillation column to an inlet of a second distillation column is provided. The second distillation column operates at a higher pressure than the first distillation column, and the inlet of the second distillation column is at higher elevation as compared to the outlet of the first distillation column. The method advantageously transfers the first liquid from the outlet to the inlet by mixing with a sufficient amount of a lower density second liquid that results in a mixed liquid having a reduced density as compared to the first liquid.
