Modelling of high pressure CO2 absorption using PZ+AMP blended solution in a packed absorption column

A rate-based steady-state model for CO2 absorption into a PZ+AMP blended solution is presented by taking into account the column hydraulics, mass transfer resistances and chemical reactions. The simulation results were compared with the experimental results of CO2 absorption by a PZ+AMP blended solu...
