Experimental studies and simulation of the dynamic hehaviour of bubble column reactors

To meet the growing demand for dynamic simulation in chemical engineering a one-dimensional mathematical model for the dynamic behaviour of bubble column reactors is developed and implementated as a computer programme. To validate some basic model assumptions and to show the abilities of the pro- gramme, experimental observations are compared with simulation results. The absorption of carbon dioxide into aqueous sodium hydroxide solutions is choosen as an example of a fast gas-liquid reaction system. For this model system a sufficiently good quantitative agreement is obtained
