The bulk separation of mixtures (in contrast to the removal of trace components) into high-purity products by adsorption requires a countercurrent flow of phases as in other equilibrium-based separations. The moving-bed adsorber, which offers the eountercurrent flow of the phases, was used for the separation of a gaseous mixture of hydrocarbons using activated carbon as adsorbent.lt is known as a hypersorber. Though it performed well, it... 

Figure 9.2-4 shows a moving bed adsorber in which sulfur oxides and nitrogen oxides are adsorbed on downward moving activated coke. The flue gas is flowing in radial direction from the center to the rim in crossflow to the coke. The advantage of such a crossflow is that the pressure drop of a huge flue gas flow is small thanks to a short path length of the gas. This is also fine for the fixed bed adsorber depicted in Fig. 9.2-5. This equipment allows the treatment of huge gas streams with the advantage that the pressure drop and also the heat losses are low.

The solid supported extractants can be employed in fixed bed contactors to extract metal ions from solutions. Other geometries include slurry extractors and moving bed adsorbers. We consider a fixed bed geometry. In this case the following mass transfer processes may be present (1) interpellet mass transfer, which refers to the diffusion and mixing of metal ion in fluid occupying the spaces between pellets (2) interphase mass transfer, which is the transfer of metal ion across the fluid peUet interface and (3) intraparticle mass transfer, which is the diffusion of metal ions in...
