Abstract
In this study, the effect of the presence of g_  catalyst in 3 M methyl diethanolamine solution for removing carbon dioxide and regenerating the solution has been investigated. According to the results obtained from this research, this catalyst has caused an increase of 6.3 to 17.9 percent in the amount of carbon dioxide removal. Also, in this research, the effect of adding monoethanolamine with a concentration of 1 M and also piperazine with a concentration of 0.5 M to a base solution of 3 M methyldiethanolamine has been investigated. The results of this research showed that by adding different amines with specific concentrations to the methyldiethanolamine solution, it is possible to increase the amount of carbon dioxide removal. The amount of carbon dioxide removal increased to 26.1% in this stage. In all the experiments, the highest amount of carbon dioxide removal was related to the three-amine mixture and applying 45 grams of g_  catalyst, which increased the amount of removal to 39.3%.
