4. Analysis of the CO2 absorption process
As the relative errors of simulation results in the test 34R1 are the lowest, the operating parameters in this test were set as the base conditions in the analysis of the CO2 absorption and regeneration processes. The flow rate, the NH3 concentration, the CO2 loading, and the temperature of the lean solvent flowing into the absorber are 67 L/min, 2.535 mol/L, 0.23, and 15 °C, respectively.
