Facilitated transport membranes have great potential for carbon dioxide removal. By coupling the solution diffusion mechanism and the facilitation effect of the chemical reaction, CO2 transport in such systems is substantially higher compared to other gases, like nitrogen and methane. The presence of water is needed in the membrane to activate the reaction mechanism, and affects the sorption and diffusion of all the gases in the membrane. The present work focuses on the modelling of water sorption in purified Lupamin® (polyvinylamine (PVAm)), with the PC-SAFT Equation of State (EoS) (Gross and Sadowski, 2001). The work is aimed at finding the best parameters and association schemes to model the water sorption in PVAm with the PC-SAFT model, in order to use it to model more complex situations such as the multicomponent sorption in the system.

Abstract
Facilitated transport membranes have great potential for carbon dioxide removal. By coupling the solution diffusion mechanism and the facilitation effect of the chemical reaction, CO2 transport in such systems is substantially higher compared to other gases, like nitrogen and methane. The presence of water is needed in the membrane to activate the reaction mechanism, and affects the sorption and diffusion of all the gases in the membrane. The present work focuses on the modelling of water sorption in purified Lupamin® (polyvinylamine (PVAm)), with the PC-SAFT Equation of State (EoS) (Gross and Sadowski, 2001). The work is aimed at finding the best parameters and association schemes to model the water sorption in PVAm with the PC-SAFT model, in order to use it to model more complex situations such as the multicomponent sorption in the system.File | Dimensione | Formato | |
