KOCHETOV'S VERTICAL ADSORBER Russian patent published in 2014 - IPC B01D53/02 

FIELD: process engineering.

SUBSTANCE: invention relates to adsorption equipment to be used in gas (vapour)-adsorbent system. Adsorber has cylindrical case with cover and bottom. Loading port is arranged in cover as well as union to feed initial mix with distribution screen, union to discharge vapours in desorption and safety valve union. Note here that stiffness ring is arranged at the butt between cover and case. Case mid part is furnished with beams with supports arranged on support ring to support fire-grate with gravel layer applied thereon. Layer of adsorbent is arranged between gravel layer and screen whereon weights are arranged to prevent adsorbent loss in desorption. Used adsorbent is discharged via discharge port in case. Bubbler is mounted in bottom as well as inspection port with union to discharge condensate and to feed water. Toroidal bubbler is secured to bottom taper surface by cross-pieces. Bubbler cylindrical surface perforation factor makes K=0.5-0.9. Purified gas discharge union is arranged at bottom conical surface. Note here that adsorption and desorption processes proceed at the following optimum ration of hardware elements. Housing height H relates to its diameter D as: H/D=0.73…1.1. Housing height H relates to its wall thickness S as: H/S=220…275. Adsorbent layer height H₁ relates to said H _as: H₁/H=0.22…0.55. Adsorbent layer height H₁ relates to said H₂ as_: H₁/H₂=5.0…12.0. Note also that adsorbent is shaped to ball, hollow or solid cylinders, grains of arbitrary surface. Or, as short lengths of thin-wall tubes or identical-size rings in height and diameter: 8, 12, 25 mm.

EFFECT: higher quality of separation.
