Abstract
1338752 Separating hydrocarbons by adsorption TORAY INDUSTRIES Inc 21 July 1971 [23 July 1970 3 Aug 1970] 34138/71 Heading C5E In a process for continuously separating, in liquid phase, the components of a liquid feed mixture, at least one of which is selectively sorbed by contact with solid sorbent particles, utilizing a simulated countercurrent flow system wherein liquid streams are allowed to flow through three serially and circularly interconnected zones; a desorption zone, a rectification zone and a sorption zone, each zone being divided into a plurality of serially interconnected sections, each section being packed with a mass of said solid sorbent particles, by introducing desorbent into the first section of said desorption zone, withdrawing a desorption effluent comprising a selectively sorbed component from the last section of said desorption zone, introducing said liquid feed mixture into the first section of said sorption zone and withdrawing a raffinate effluent comprising a less sorbed component and said desorbent from said sorption zone, and all the points of introducing and withdrawing said liquid streams into and from said sections are simultaneously shifted, one section at a time at stated intervals of time, in a downstream direction while maintaining the same order of continuity and the same spatial relationship between said points, an improvement characterized by interrupting said liquid streams flowing through said three zones at a point between said desorption zone and said rectification zone while the first portion of said desorption effluent flowing out from said last section of said desorption zone, which portion contains either a little or no desorbent but contains said selectively sorbed component, is directly circulated into the first section of the desorption zone and the second portion thereof which portion contains said selectively sorbed component of high purity, but at a lower concentration than the first portion, is introduced into the distillation apparatus from which one portion of the sorbate fraction is circulated both as reflux into the first section of the rectification zone. The examples describe the separation of a mixture of xylene isomers using a crystalline aluminosilicate (e.g. faujasite-type) adsorbent, but other separations mentioned are olefins from paraffins, and aromatic from non-aromatic using silica gel or active charcoal as sorbents.
