Energy Consumption in Binary Batch Distillation of Total Reflux and Top Accumulation

The numeric method of the total quantity of ineffective reflux on tower top of binary batch distillation of total reflux and top accumulation under and ideal operation conditions is introduced. Energy consumption of binary batch distillation under total reflux and top accumulation is analyzed using the calculated results of examples，and a conclusion that, for the separation task that the low-efficiency energy consumption is large in proportion to its total energy consumption , its total energy consumption is visibly reduced by making a reduction in the mixing level of flowing liquid in top vessel.
