Abstract:
A process for distilling a fluid in an apparatus having multiple-effect plates and including an evaporation zone and a condensation zone, comprising the steps of:vertically arranging the evaporation zone and the condensation zone, and separating the vertically arranged evaporation zone and condensation zone with a longitudinal central member, forming a cell having fluid-receiving walls; introducing the fluid to be distilled into an upper part of the evaporation zone so that the fluid runs as a thin film down the walls of the cell, condensing the fluid and producing vapors in the evaporation zone; horizontally transferring the vapors produced in the evaporation zone into the condensation zone through calibrated holes provided in the central member; and evacuating the condensed fluid running vertically down the walls of the condensation zone from a lower part of the condensation zone.
