Absorption of CO2 by Aqueous AMP in Packed Column

The advantages of using AMP as absorbent for the absorption of CO2 is the high rate of absorption, less corrosion, and low energy of recovery, also low stability of the absorbed amino product which is easy to hydrolyze to liberate free AMP. 

The reaction between AMP and CO2 can be represented by the following steps with liberation of heat of solution and reaction  

The object of simulation, a pilot-scale packed column, is the same as given in Sect. 

Ten sets of experimental data for absorption of CO2 by AMP aqueous solution were reported by Tontiwachwuthikul et al. [24], in which three sets are taken as examples for comparison with present simulation. 

The determination of source terms in the modeling equations is similar to Sect. 5.1.1.2 except the physical parameters should be reevaluated. Refer to Ref. [26] for details.
