Process of hydrazine hydrate production by acetone azine hydrolysis via catalytic distillation
摘要
Abstract
The process of hydrazine hydrate produced by acetone azine hydrolysis via catalytic distillation was simulated and experimented.By using NTRL equation and RadFrac module,as well as the data obtained from dynamics and phase equilibrium,the process of producing hydrazine hydrate by acetone azine hydrolysis via catalytic distillation was simulated.The effects of process parameter,such as reflux ratio,mole ratio of acetone azine to water and feeding location on the acetone azine hydrolysis reaction were investigated.The optimized process parameters obtained were as follows:theoretical tray number 5 for rectifying,theoretical tray number 14 for reaction,reflux ratio 2,the mole fraction of acetone azine to water 1:7,feed tray 9th tray.Under such conditions,the hydrolysis rate of acetone azine was over 99％,the mass fraction of hydrazine hydrate at bottom was 34％ and the temperature and mass fraction distributions of whole column were got.It provides a reference for industry production.关键词
