Abstract:
1. A vapor distributor, for use in a gas-liquid contacting column, comprising: a first vapor feed that feeds laterally into the column; a second vapor feed that rises vertically from a portion of the column below the vapor distributor; a vapor inlet pipe having a nozzle that feeds the first vapor feed into a vapor inlet device comprising first and second housings and a plurality of vanes; the nozzle being divided into a first opening that directs a portion of the first vapor feed as a first stream traveling along the first housing and a second opening directing the remaining portion of the first vapor feed along the second housing; the first and second housings being situated closely adjacent the walls of the column, and progressing horizontally in opposed directions about the inside of the column so that the directions of flow of the first portion and the second portion of the first vapor feed are also opposed; a plurality of vapor directing vanes in each of the first and second housings that redirect flow of the first vapor feed so as to distribute the first vapor feed across the cross-sectional area of the column; and a vapor mixer secured within the column, and the vapor mixer serving as a static mixer, dispersion device and vortex breaker.
