Review of technological methods and experimental determination of thermodynamic and transport properties of reagents for carbon dioxide removal from flue gases

In this work a review of the currently available methods for carbon dioxide removal from flue gasses is given. Some of them are commercially available, while others are still under development. Special attention is given to detailed description of the methods based on hemi sorption by aqueous solutions of alkanol amines, which found wide commercial use in industry. Selection of appropriate absorbent, process equipment, methods, working parameters, combustion process etc. are some of key points that will be reviewed within this work in order to present advantages and limitations of carbon dioxide removal methods. In the experimental section density, viscosity and refractive index of insufficiently investigated carbon dioxide removal agents, such as monoisopropanolamine (MIPA), diisopropanolamine (DIPA), triisopropanolamine (TIPA) and currently widely used dietanolamine (DEA) are provided. The data obtained are crucial for the equipment design and process optimization.
