The Effect of Sweeping Media and Temperature on Aqueous CO2 Removal Using Hollow Fiber Membrane Contactor (HFMC): An Experimental Determination

Transport phenomena through hollow fiber membrane contactors (HFMCs) indicate the exchange of a component between two phases, inside and outside fibers. In this research, we designed fabricated lab-made HFMCs to assess difference water air as sweeping media for CO2 exchange. The effects flow rates temperature ratios on aqueous absorption were investigated accordingly. A semiclosed circuit incorporating our was set up regulate operating parameters evaluate concentration using an initiative pH-based method. results experiments remarkably reveal that tends remove more than when is higher 3.53 × 10−6 mlCO2/l. However, would surpass in lower concentrations. Nevertheless, tripling rate from 500 1500 ml/min shifts cutoff point 50 times around 1.66 10−4 performed at three different 22 : 22, 44 12, 12°C (CO2-rich liquid: medium) demonstrated gradient deteriorates capacity media. Nonetheless, becomes highly effective concentrations 1.57 CO2/l. research could be applied performance optimization absorbing HFMCs, even sophisticated medical procedures such arterio-venous veno-venous removal systems where both used blood’s
