Abstract: The membrane-based CO2 separation process has an advantage compared to traditional CO2 separation technologies. The membrane is the key of the membrane separation process. In this paper, preparation, characterization and laboratory testing of the membrane, which was prepared from sodium alginate, hydrogen bond cross-linked with sodium tartrate and used for CO2/N2 separation, were reported. The resistance to SO2 of the membrane was also investigated. The experimental results demonstrate that the membrane possesses a high resistance to SO2. Finally, based on experimental results, the economic feasibility of the membrane used for CO2/N2 separation was evaluated, indicating the two-stage membrane process can compete with the traditional chemical absorption method.
