The modeling and simulation of semi-batch external loop spray ethoxylation reactor was studied.By analyzing the characteristics of the reactor
a mathematical model and numerical algorithm were developed to describe the behavior of the reactor.The model took the vapor-liquid transfer
kinetics
vapor-liquid equilibrium
variation of reactive volume
as well as the effect of inert gas nitrogen on the reactor into account.Based on the developed model
simulations were performed by taking the production of polyethylene glycol as an example.The simulation results provided the typical dynamic profiles of the reactor temperature
pressure
ethylene oxide concentration
as well as the ethoxylated oligomer distributions.Simulation results were compared with the full-scale plant data
which showed the reliability of the developed mathematical model.
