对羟胺制备和肟化反应器的类型和物料的流动方式进行了分析。根据物料衡算及能量衡算的关系式,结合磷酸羟胺(HPO)法制备环己酮肟的反应动力学模型,建立了羟胺制备反应器的全混流和羟胺肟化反应器的活塞流动态数学模型,得到了环己酮转化率。模拟结果与实际生产过程相符,表明建立的模型可以准确的模拟工艺过程。

Dynamicsimulation of hydroxylamine preparation and an oximation process

The effects of different types of feedstock flow in the preparation of hydroxylamine and a subsequent oximation reaction have been analyzed by dynamic simulations. According to the material balance, energy balance equation, and a kinetic model of the phosphoric acid hydroxylamine process (HPO process) for the preparation of cyclohexanone oxime, a dynamic mathematical model, which involves a mixed flow in the hydroxylamine preparation reactor and a piston flow in the hydroxylamine oximation reactor, has been established. Thereby, the extent of conversion of cyclohexanone was obtained. The results of the simulations are consistent with those of actual production process, showing that the model established here can simulate the process accurately.
