@article{(Open Science Index):https://publications.waset.org/pdf/4320, title = {CFD Simulation of Dense Gas Extraction through Polymeric Membranes}, author = {Azam Marjani and Saeed Shirazian}, country = {}, institution = {}, abstract = {In this study is presented a general methodology to predict the performance of a continuous near-critical fluid extraction process to remove compounds from aqueous solutions using hollow fiber membrane contactors. A comprehensive 2D mathematical model was developed to study Porocritical extraction process. The system studied in this work is a membrane based extractor of ethanol and acetone from aqueous solutions using near-critical CO2. Predictions of extraction percentages obtained by simulations have been compared to the experimental values reported by Bothun et al. [5]. Simulations of extraction percentage of ethanol and acetone show an average difference of 9.3% and 6.5% with the experimental data, respectively. More accurate predictions of the extraction of acetone could be explained by a better estimation of the transport properties in the aqueous phase that controls the extraction of this solute.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {4}, number = {1}, year = {2010}, pages = {127 - 131}, ee = {https://publications.waset.org/pdf/4320}, url = {https://publications.waset.org/vol/37}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 37, 2010}, }
