A new application of catalytic distillation (CD) for the production of ethylene glycol monobutyl ether (EGMBE) from ethylene oxide (EO) and n-butanol was developed.A pilot-scale CD column was built up
which was operated in a semi-batch mode for safety consideration.A dynamic model was developed for the description of the semi-batch CD process.Simulations were performed to investigate the effect of feed flow rate of EO on conversion of reactants and selectivity toward EGMBE
so as to obtain the optimal and safe operating conditions.The simulation provided the typically dynamic profiles of the liquid and vapor flow rates
compositions and temperature
which were compared with the experimental data.The results obtained indicated the model developed was reasonable
and also the potential advantage of using CD for the production of EGMBE.
