Study on total reflux operation in batch distillation 分批精馏中全回流操作的研究
total reflux operation 全回流操作
A controlling method of total reflux by introducing temperatures of middle part and top part in batch distillation column was set up, and isopropanol and n-propanol were used to conduct the experimental study of this operation. 摘要提出了采用塔顶和塔中温度进行控制操作状态转换的全回流间歇精馏控制方法，并以异丙醇－正丙醇为实验物系进行了实验研究。
The examples in this tutorial model the 24-plat column both in steady state operation (steady state continuous operation and total reflux) and in dynamic mode ( with total reflux and with distillate withdrawal). 在本教程中，24盘的蒸馏塔既用来做稳态操作（包括稳态连续生产和全回程操作）也用来做动态模型试验。
A novel operation mode of cascaded total reflux batch distillation with dynamic exchange of liquid phase(CTBDEL)is proposed according to the advantage of total reflux dynamic accumulation operation. 本文针对全回流动态累积操作分离效率高、控制简便的优点提出了动态液相交换的全回流间歇精馏串联过程的新型操作方式。
The initial charge in the reboiler, heating style and reflux operation may be variable from batch to batch. 然而在没有动态模拟的情况下，启动过程主要根据经验进行操作，不可能、也不允许直接在装置上做任何试验。
