精馏塔压力控制系统分析研究

The Study of Common Pressure Control Methods in Rectifying Columns

精馏塔是化工生产中广泛应用的设备,维持精馏塔压力的稳定对精馏塔的操作以及产品质量的管控至关重要.不同类型的精馏塔会采用不同的方法对压力进行控制,本文中介绍了常见的几种精馏塔压力控制,分析了不同压力控制方案的优缺点及适用环境,同时也列举了一些特殊工艺需求引申出的特殊压力控制方案.

Rectifying column is widespread used in chemical industry production.It is absolutely vital to maintain the pressure of rectifying columns in the operation of rectifying columns and in the quality control of products.As a variety of ways of pressure control methods applied to different types of rectifying columns,common rectifying column pressure control methods are introduced in this essay,analyzed the merit and demerit and the scope of application of them.Meanwhile,some unusual pressure control methods are enumerated applied to special process requirements.
