基于膜的 CO2 分离过程与传统的 CO2 分离技术相比有一个优点。膜是膜分离过程的钥匙。在膜,它从钠 alginate 被准备测试的这份报纸,准备,描述和实验室,有钠酒石酸盐的氢契约 cross-linked 并且为 CO2/N2 分离使用,被报导。到膜的 SO2 的抵抗也被调查。试验性的结果证明膜拥有一个高电阻到 SO2。基于试验性的结果,最后,膜的经济可行性使用了因为 CO2/N2 分离被评估,显示二阶段的膜过程能与传统的化学吸收方法竞争。
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, characteriza-tion 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.
