环己酮氧化反应器的贫氧控制

Lean Oxygen Control of Cyclohexanone Oxidation Reactor

在环己酮生产过程中 ,影响环己酮产品质量的因素很多 ,其中最为显著的是供入氧化反应器的贫氧控制。介绍了环己酮氧化反应器的贫氧控制系统及其特点 ,即氮气流量和空气流量均构成了闭合回路 ,贫氧和空气或氮气又构成了串级控制系统 ,并根据环己酮生产的工艺要求 ,详述了贫氧控制系统的控制过程。

There are a many factors influencing the quality of the cyclohexanone product during the cyclohexanone production,the most significant one is the control of lean oxygen feeding the oxidation reactor.The lean oxygen control system of the cyclohexanone oxidation reactor and its features are introduced,that is,both the nitrogen flow and air flow form closed loops,and the lean oxygen and air or nitrogen form a cascade control system.The control flow is the lean oxygen control system is described in detail according to the process requirements of the cyclohexanone production.
