Since CO2 separation membrane requires a high permeance, a thin-film composite membrane having a thin selective layer has been manufactured. However, defects are prone to occur in the preparation of TFC membranes which have thin selective layer, especially large-scale membranes, and as a result, the CO2 separation properties are reduced. Therefore, we demostrate the effect of defects on gas separation properties in TFC membranes. In order to control the defect, a defect-free large-scale membrane was manufactured by introducing protective layer. The gas transport properties were studied in single and mixed gas, and membrane module was tested in the same composition as the real process gases. |
