Webb29 okt. 2024 · Abstract. In this chapter, batch distillation is covered. The design of a batch distillation is difficult because the composition in the batch continuously changes during the course of the distillation. The separation becomes more difficult if the concentration of the light boiler in the batch gets smaller. The reflux ratio must be increased.
