To obtain design criteria of fixed-bed adsorbers for solvent recovery, experimental breakthrough curves were measured for single-, binary- and ternary-solvent vapor-activated carbon systems and for the same concentration ranges and the same flow rate as those used in industry. Equilibrium relationships for each system were determined from experimental results. It became clear that the binary and ternary adsorption equilibria could be expressed by the Markham–Benton equation. Analyses of the experimental breakthrough curves by the extended MTZ method and by a rather rigorous numerical calculation showed that the intraparticle diffusion of each component was governed by surface diffusion. Furthermore, break times for binary and ternary systems were well predicted by use of the extended MTZ method, with the same accuracy as when the numerical calculation was adopted.
