Abstract
<PICT:0714870/IV (b)/1> <PICT:0714870/IV (b)/2> <PICT:0714870/IV (b)/3> Apparatus for separating, by selective adsorbents, organic liquids such as aromatics or olefins from hydrocarbon liquids containing them in admixture with saturated hydrocarbons, the adsorbed constituents being thereafter desorbed by another liquid, comprises a casing 10 housing a bed 18, Fig. 2, of granular adsorbent and having a flat closure member 11 at its inlet end, a perforated plate 19 parallel to, and separated by a distance less than two inches and less than one thirty-sixth of the diameter of the exposed face from, the member 11 and extending across the casing inlet, means such as inlet pipes 13 for introducing liquid into the space between the member 11 and the plate 19, the number and size of the perforations in the plate being such that the liquid pressure drop through the plate perforations is greater than the maximum liquid pressure drop from the pipes 13 to the perforations, and a screen 23 adjacent to the inner side of the perforated plate 19 to maintain the particles of the bed out of contact with the perforations. The walls 10 are preferably tapered at an angle of 20-50 degrees with the vertical for a short distance adjacent the inlet to provide increasing cross-sectional area in the direction of flow. The distribution effected by the plate 19 may be enhanced by a screen 22 of relatively coarse mesh interposed between the screen 23 and the plate 19. The space between the closure member 11 and the plate 19 is provided by a spacer ring 20 which may however be replaced by a shoulder on the member 11. The outlet end of the casing is closed by a member 15, Fig. 4, having in its inner surface grooves 25, Fig. 5, communicating with the ends of outlet pipes 16. A screen 26 prevents clogging of the grooves. If the liquid flow is to be upward the lower end of the adsorber is provided with distributing means and the upper end with outlet means. Preferably the outlet end is not tapered in each case.ALSO:<PICT:0714870/III/1> <PICT:0714870/III/2> <PICT:0714870/III/3> Apparatus for separating, by selective adsorbents, organic liquids such as aromatics or olefins from hydrocarbon liquids containing them in admixture with saturated hydrocarbons, the adsorbed constituents being thereafter desorbed by another liquid, comprises a casing 10 housing a bed 18, Fig. 2, of granular adsorbent and having a flat closure member 11 at its inlet end, a perforated plate 19 parallel to, and separated by a distance less than two inches and less than one thirty-sixth of the diameter of the exposed face from the member 11 and extending across the casing inlet, means such as inlet pipes 13 for introducing liquid into the space between the member 11 and the plate 19, the number and size of the perforations in the plate being such that the liquid pressure drop through the plate perforations is greater than the maximum liquid pressure drop from the pipes 13 to the perforations, and a screen 23 adjacent to the inner side of the perforated plate 19 to maintain the particles of the bed out of contact with the perforations. The walls 10 are preferably tapered at an angle of 20 degrees-50 degrees with the vertical for a short distance adjacent the inlet to provide increasing cross sectional area in the direction of flow. The distribution effected by the plate 19 may be enhanced by a screen 22 of relatively coarse mesh interposed between the screen 23 and the plate 19. The space between the closure member 11 and the plate 19 is provided by a spacer ring 20 which may, however, be replaced by a shoulder on the member 11. The outlet end of the casing is closed by a member 15, Fig. 4, having in its inner surface grooves 25, Fig. 5, communicating with the ends of outlet pipes 16. A screen 26 prevents clogging of the grooves. If the liquid flow is to be upward the lower end of the adsorber is provided with distributing means and the upper end with outlet means. Preferably the outlet end is not tapered in each case. In an example the casing 10 has a diameter of 10 feet and is tapered at an angle of 30 degrees towards the inlet end to an inlet diameter of 6 feet. The spacing between plates 11 and 19 is 3/8 inch, the plate 19 has 320 holes of 5/32 inch diameter, and the screens 22 and 23 are of 1/4 inch mesh and 100 mesh respectively. Four pipes 13 are provided. The purpose of the invention is to effect sharp separation between charge liquid and desorbent.
