| Abstract: | By using the simultaneous reaction and shuttle mechanisms, change of the chemical absorptio hand desorption in liquid phase, with M simultaneous reactions has been discussed on this bases, the mechanism of compound promotion of DEA and Glycine which are used in hot potash solution has been studied and the mathematical models were given. To measure the rates of absorption or desorption of CO_2 in modified potash solution containing different amount of promoters, an experimental study was done in an absorption cell with a stirring device or a desorption flask of three mouths. Parameters of mathematical models have been obtained by the regression analysis on the experimental data. The above study might provide guidance for the improvement of the Benfield technology and the nonpoiso-nous G-V technology. |
