Description of the Gas Transport through Dynamic Liquid Membrane.
Original language description
Recently we published a short communication about the gas separation by new type of membranes so called dynamic liquid membranes (DLM). The gas transport through water film was described by solution diffusion model commonly used for evaluation of the gas permeation through nonporous polymeric membranes, therefore this type of membranes is suitable for the separation of such systems where one of the components has high solubility in water. The separation ability of DLM based on thin water film for the binary mixtures of carbon dioxide and methane was investigated. Since direct measurement of permeate flux and its composition was not possible, we suggested three models for gas transport evaluation based on the use of simplifying assumptions. The obtained values of carbon dioxide permeate flux (permeance) from all models are very close, the highest difference is 6.3 mol % for feed composition 92 mol % CO2. Carbon dioxide flux is between 0.048 and 0.729 m3 m-2 h-1. The results of carbon dioxide permeation flux determined as difference between experimental values of the feed and retentate fluxes with permeate flux calculated using the Model 3 were in very good agreement.
