Fig. 3

Atmospheric distillation processes representing a scenario 1 and b scenario 2. The flow rate in feed (stream 1) was 1025 kg/h. The red data are the higher-energy cost columns while the green data relatively required less energy in the corresponding columns. Black data refers to the heating and cooling energy that remained similar when recycling the water and butanol distillates. Feeding plates as well as the overall plates of each column were also shown in this figure. The overhead pressures of the columns were all set at atmospheric pressure
