Abstract
An introduction and overview of the work is given in Chapter 1. In Chapter 2, a description of the equipment and the kinetics modelling used in this thesis is explained in detail. Chapter 3 includes an overview of traditional solvents and shows the kinetics and mass transfer results of the absorption of CO2 in amine solvents. Chapter 4 starts with a literature review on organic solvents and hybrid solutions (organic-amine aqueous solutions) and includes the mass transfer and kinetic results of the absorption of CO2 in selected hybrid solvents containing amines. Chapters 3 and 4 sum up the 11 solutions tested for the absorption of CO2 and include their physical characterization (density, viscosity and N2O solubility), at unloaded and loaded conditions and from 298 to 353K. Chapter 5 is focused on the thermodynamic modelling of new amine solvents in ASPEN PLUS and Chapter 6 includes the modelling at pilot plant scale of absorber and desorber. Every chapter includes conclusions and final remarks are given at the end of this thesis. Chapter 7 presents the conclusions of the whole thesis and recommendations for future work.
