Literature review evaluates experimental carbon dioxide solubility data in aqueous amine solutions, highlighting optimal parameters for industrial gas capture.
High Resolution Image Download MS PowerPoint Slide Chemical absorption is one of the most applied and efficient methods for CO 2 removal, and it is primarily employed in the processes related to the production of energy (natural gas, power plants, etc.). This work is the first review focusing on bibliographic research related to experimental data of CO 2 solubility in the MDEA+PZ aqueous solution, which is of interest for the CO 2 removal from several types of gaseous streams in important industrial and environmental processes. An in-depth review of the available experimental setups and procedures for collecting points of CO 2 solubility in the MDEA+PZ solvent is presented. The main methods to measure and compute the solubility of the acid gas in the solvent are analyzed, and the experimental points from all the sources are detailed and compared, considering different values of temperature, pressure, CO 2 loading, and composition of the solvent, as for the content of MDEA and that of PZ.
