Review of traditional flue gas treatment methods and potential membrane materials for enriching SO_2 and NO from the flue gas

摘要

a. Disadvantaces of traditional flue gas desulfurlzation and" denitrificatidh technologies 1. Large operation space 2. High cost for catalyst regeneration and waste treatment 3. Low removal efficiency caused by the low concentration a. Apoly membrane separation technology to enrich SO_2 and NON in the flue gas 1. It can perform the separation close to thermodynamic limit of de-mixing 2. No need for high energy input and large space 3. No phase change 4. Large functional area can be provided by a compact device a. PEBAX composite with PEO/GO/POSS are promising materials for sour gas separation.
