| Abstract: | The model for the simulation of the cyclic steady-state performance of simulated moving bed(SMB) adsorption system for industrial paraffins separation process was developed based on the analogy with the transient true moving bed(TMB) system.The finite-element collocation method was used to solve the partial differential equations of the model.The effects of operating variables,such as switch time of rotary valve,extract flow rate,feed flow rate and desorbent flow rate on SMB performances were analyzed.The SMB performance was characterized in term of recovery and adsorbent productivity in the analysis.The simulated results are in good agreement with the design values of industrial paraffins separation process,and provide the basis for the optimization of technology design and for the reduction of energy consumption. |
