摘要
压力和温度是精馏塔控制中比较重要的两个被控变量,首先对精馏塔的各种压力控制方案进行了介绍,并说明了它们的适用场合,接着介绍了精馏塔的温度控制方案。在上述基础上,给出了精馏塔的几个基本控制方案,并对原油常压蒸馏塔的工艺控制方案进行了分析。
The pressure and temperature are two important variables controlled in distillation column control, firstly, all kinds of pressure control schemes for distillation column are intro- duced respectively, including the situations applied, and then introduces the temperature control schemes for distillation column. Based on the above mentioned, the basic control schemes for distillation column are indicated, finally process control scheme for the crude oil atmospheric distillation is analyzed.
