摘　　要：采用正丙醇-异丙醇混合物为分离物系,在动态累积间歇精馏理论基础上,提出了一种新的采用塔釜回流的操作方式,并在常规动态累积与精馏节能方面进行了对比。实验结果表明,在确保塔顶异丙醇产品纯度达到85%的条件下,节省了操作时间,进而可节约17%~33%的能耗,且收率提高1.5%~2.2%。A novel operation mode by reflux at bottom was put forward based on the theory of the dynamic-accumulation batch distillation.1-propanol-isopropanol mixture as the separated system,compared with the conventional dynamic-accumulation distillation in energy saving was studied.The results show that the novel operation mode can reduce the operating time with the purity of isopropanol over 85% on the top of column,and energy consumption was saved by 17%-33%.At the same time,the yield percentage of product recovery increased by 1.5%-2.2%.
