Abstract

The present invention relates to a distributor for distributing a liquid in an exchange column. The distributor comprises at least one predistributor means positioned to receive a liquid feed and a plurality of distributor means having substantially straight longitudinal side walls and open top portions. The interior and exterior of the longitudinal side walls of the predistributor means are covered with a wettable, open-pore material. In operation the liquid feed flows from the predistributor means into the interior of the distributor means, through the open-pore material, exiting this open-pore material on the exterior of the distributor means. In this manner an improved, even distribution of the liquid feed within the exchange column is obtained.
