The membrane-based CO
2
separation process has an advantage compared to traditional CO
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 CO
/N
separation
were reported. The resistance to SO
of the membrane was also investigated. The experimental results demonstrate that the membrane possesses a high resistance to SO
. Finally
based on experimental results
the economic feasibility of the membrane used for CO
separation was evaluated
indicating the two-stage membrane process can compete with the traditional chemical absorption method.
