Abstract: This study evaluated the feasibility of a chemical process which uses desalination brine to convert CO2 into useful sodium bicarbonate. The process is based on the integration of a modified Solvay process with conventional amine based post-combustion carbon dioxide capture for the simultaneous capture and conversion of CO2 into solid bicarbonates. A range of amine solvents were evaluated to select the most suitable solvent for the process. Then the effects of parameters such as temperature, brine concentration and amine concentration on the carbonation step of the process were evaluated. Moreover, different techniques for recovering the amine from the chloride rich solution were proposed and investigated.
