Modeling and Characterization of Liquid Vapor Equilibrium of N-methyl-1,3-Propanediamine for CO2 Capture - Using the Extended UNIQUAC Framework
MetadataVis full innførsel
In this work the loaded MAPA system has been thermodynamically characterized. This was done by measuring the phase- and chemical equilibrium in the laboratory, as vapor - liquid - equilibrium data. A thermodynamical model that was based on the extended UNIQUAC activity coefficient framework was used in an attempt to model these data. The parameters of the extended UNIQUAC model and the unknown carbamate equilibrium constants were determined in an regression analysis where the experimentally determined data were used. The parameters and equilibrium constants found are able to predict the experimental data accurately below loadings of one.
