dc.description.abstractPolyvinyl amine (PVAm) Fixed-Site-Carrier (FSC) membranes prepared with various casting solution pH were developed for CO2 capture from flue gas. Among these membranes tested, the membranes prepared from casting solutions of pH X and Y showed the best results. In this thesis a general trend was displayed for the PVAm FSC membrane of increased separation performance with increasing casting solution pH used to prepare the membranes. This general trend applied for the PVAm FSC membranes tested at feed pressures from 1.1 bar up to 8 bar. The effect of NO2 contamination on the separation performance of the PVAm FSC membrane was investigated. PVAm FSC membranes prepared from casting solutions of pH Z and pH X were contaminated with NO2 at 50°C and tested before and after exposure at 1.1 bar, 5 bar and 8 bar. Both PVAm FSC membranes showed degradation by the NO2 exposure. For the PVAm membrane prepared at pH Z the separation performance was drastically reduced after NO2 exposure at 1.1 bar feed pressure and maximum feed saturation. At 5 and 8 bar feed pressure the PVAm FSC membranes showed an increased separation performance after NO2 exposure.nb_NO
