Simultaneous carbon dioxide capture and utilization using thermal desalination reject brine

The sterically hindered amine, 2-amino, 2-methyl propanol (AMP), was found to be the best alcohol amine for the process and the CO2 absorption step was found to be significantly improved at lower temperatures, high brine concentrations and moderate amine concentration. For AMP, the optimum concentration was found to be 30 wt%. Finally, the amine recovery technique tested showed promise and could be optimized further to give better results.
