| Aqueous amine solutions are widely used for the removal of H;Degradation of MDEA-DEA mixtures was studied by contacting the amine mixture with CO;Different methods were examined to purify degraded DEA solutions; such as ion-exchange resins, vacuum distillation and reversing the degradation reactions by NaOH treatment. Vacuum distillation was found to be ineffective while the other two methods were partially effective in purification of degraded solutions. |
