丙烯酸反应器操作区域的计算

The Calculation of the Operation Area of a Acrylic Acid Oxidation Reactor

在丙烯氧化生成丙烯酸反应中存在两个爆炸区域,氧化反应的操作点必须远离该区域。丙烯、空气、蒸汽和循环气的流量、压力和温度测量值是关键的检测参数,同时需考虑这四种介质的设计温度和设计压力。具体探讨了氧化反应操作点的确定主要是计算丙烯和惰性气体的摩尔百分数,并对气体介质摩尔流量进行补偿。基于操作点计算出反应器条件区域、混合器条件区域、催化剂保护区域等,保证丙烯酸氧化反应的正常运行,该计算方法已成功应用于实际装置中。

There exist two explosion areas in the oxidation reaction. The operation point of reaction should be located far from the two explosion areas. The flowrate, temperature and pressure of propylene, air, steam and cycled gas are very important measurement parameters. Their design temperature and pressure should be considered. The operation point shall be determined based on calculating of mole percent of propylene and inert gases, and mole flowrate compensation. The reactor conditions area, the mixer conditions area, catalyst protection area should be calculated based the operation point to ensure normal operation of the acrylic acid oxidation reaction. The calculaticn method has been applied in the acrylic acid practical plant successfully.
