A dilute feed of 3-phenyl-1-propanol (A) and 2-phenyl ethanol (B) in a 60/40 wt% ratio methanol–water mixture is to be fed to a four-section laboratory SMB to separate A from B. The feed rate is 0.16 mL/minute, with 0.091 g/L of A and 0.115 g/L of B. The desorbent is a 60/40 wt% methanol–water mixture. For this dilute mixture of A and B and the adsorbent to be used, a linear adsorption isotherm applies, with K_A = 2.36 and KB = 1.40. Assume that neither methanol nor water adsorb. The external void fraction, ϵ_b, of the adsorbent beds is 0.572. A switching time of 10 minutes is to be used. Using the steady-state, local-composition TMB model for a perfect separation of A from B with β = 1.15, estimate initial values for the volumetric flow rates of the extract, raffinate, desorbent, and solid particles. Convert the value of the recirculation rate for the TMB to that for the SMB and compute the resulting volumetricliquid flow rates in each of the four sections.
