Abstract

Abstract: A rate model, which considers axial dispersion, external mass transfer, intraparticle diffusion and nonlinear isotherms, and ports periodic switching is adopted to simulate the simulated moving bed (SMB) process. The effects of flow rate in Sections 2 and 3 and switching time on the operating performance parameters: purity, re-covery, productivity and desorbent consumption are studied. A simulation approach is applied to simulate the opera-tion and performance of the SMB. The model predicts the performance of the transient and cyclic steady state be-havior to a reasonably good extent, and provides guidance operation condition of the SMB process.

Key words: simulated moving bed, modeling, simulation, soybean phosphatidylcholine
