ABSTRACT
Whereas the PCDD/F-abatement in MSWIs is mostly achieved through entrained-phase adsorption upon activated carbon, the other thermal processes are more bending towards fixed/moving bed adsorption or catalytic destruction. The treatment of entrained-phase adsorption has been previously dealt with. The present paper focuses upon fixed/moving bed adsorption as abatement alternative. The characteristics of granular carbonaceous adsorbents are reviewed and commented upon, and stress some advantages of the fixed/moving bed operation. The equilibrium adsorption characteristics are expressed in terms of the number of active sites of the adsorbent and its saturation capacity. The breakthrough calculations for a fixed/moving bed adsorber are based upon these adsorption characteristics and expressed in terms of the relevant operating parameters of the flue gases to be treated. Although detailed literature data on these adsorbers are scarce, application of the design equations predicts meaningful results, thus demonstrating the predictive capacity of the design method.
