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.

Simulation Results

The present paper investigates the simulation of carbon dioxide removal from natural gas stream by a mixture of three amines of diethanolamine (DEA), methyldiethanolamine (MDEA), and 2-amino- 2-methyl-1-propanol (AMP) in a hollow fiber membrane contactor made from polypropylene using finite volume method (FVM). The effect of structural parameters of length and thickness of membrane and diameter of shell on the removal efficiency was studied and the optimized values were calculated. The calculations were made with the assumption of two-dimensional symmetric geometry and compared with those of three-dimensional one. The effect of number and size of the meshes on the simulation results was also studied. The simulation results were validated against the experimental values from the literature. The results imply that the increase in the length and decrease in the thickness of membrane enhances the removal efficiency. As a result, higher quantities of carbon dioxide are transferred from the shell to the membrane and amine solution inside the tube which decreases the effluent CO2 of shell and increases the average concentration of CO2 in the membrane and tube sides. The changes in effluent CO2 of shell with respect to amine solution concentration and influent CO2 indicate the insignificant influence of influent CO2 concentration on the removal efficiency.
