| Abstract: | After simplification of the equilibrium relationship of the CO 2 MDEA PZ H 2O system based on the calculation results from the thermodynamic model of the system, a simple relation is derived of the CO 2 partial pressure and its degree of conversion, and two expressions of apparent equilibrium constant required for calculation are correlated. The relation can be used conveniently in the engineering calculation of the process of CO 2 removal by MDEA, and the calculation value of CO 2 partial pressure agrees well with the experimental value, with an average deviation of 11.3%. |
