Abstract	Presents results of an analysis of the possible application of membranes for CO2 separation in the treatment of non-valuable streams like flue gas, and valuable streams. Authors describe selection criteria useful in the choice of membrane gas separation for CO2 capture determine the advantages offered by membrane systems. Researchers considered membrane selectivity ranging from 30–50 to 100–500 and various feed/permeate pressure ratios for various cases. The composition and recovery of carbon dioxide in the membrane-treated stream were the target parameters taken into account as guidelines in the evaluation of the separation technology performance. They developed general maps of CO2 permeate concentration versus CO2 recovery using a simple tool that takes into account the influence of the most important parameters affecting the membrane system performance. Results suggest that the separation depends on various interrelated factors: the membrane material, the operating conditions, and the final requirements.
