【Abstract】 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.更多还原
