Abstract 

For the separation of solution with low concentration of impurities, a study on dynamic accumulation operation mode of continuous distillation (DACD) was composed, the operation scheme and the mathematical model was put forward and established. The process was simulated by MATLAB, the influence of different parameters on the operation was discussed. And an experimental verification using mixture of ethanol and 1-propanol was conducted. The results of simulation and experiment indicated that DACD could solve the shortage of flowrate control difficulty in continuous distillation, and the demand of still size could be also reduced than that in batch distillation.
