Study of dual temperature control method on cyclic total reflux batch distillation
Dual temperature control method of cyclic total reflux batch distillation by introducing middle and top temperature in batch distillation column is proposed. Two systems, isopropanoVI-propanol and ethanol/1-propanol, are used to carry out the experiments. The results indicate that the operation state switch of total reflux and total withdrawal with this method in cyclic total reflux batch distillation is completely feasible and the product yield is high.
