Abstract—Separation of cyclopentane has an important significance in environmental protection and resource utilization. This work is intended to serve as a rapid way to screen mixed solvent for extractive distillation of cyclopentane using the COSMO-RS method. IDACs and VLE data of different binary systems were compared with computational results. Then the performance of mixed solvent was studied by the COSMO-RS method, including the influences of the solvent-to-feed ratio and the basic solvent and cosolvent ratio on the relative volatility. Finally, the mixed solvent was validated to be effective by the experiments.
Index Terms—COSMO-RS, cyclopentane, solvent screening, IDACs.
