Abstract

Column has several sections arranged one above the other, each section including a platform with an overflow lip arranged above a reservoir. A cylinder through which vapour passes is mounted in each reservoir to preduce condensate which passes through an over-flow tube from the reservoir of one section onto the platform of the section below. In the improvement the over-flow lip has an extension wall extending into the reservoir. Condensate passing over the overflow lip runs down the extension wall into the reservoir. The flow rate of condensate from one section to the other in reduced, thereby improving the efficiency of the distn. process.
