摘要
在动力学研究的基础上,建立了非催化水解反应精馏过程的平衡级模型,对现行丙酮连氮水解制肼工艺进行优化,并使用化工模拟软件对该工艺过程进行模拟,考察了全塔级数、进料位置、回流比等参数对工艺过程的影响。结果表明,全塔理论级数为25级,补充水的进料位置为第5块板,丙酮连氮和水混合进料位置在第10块板,且补充水量与混合进料中丙酮连氮的摩尔比为1,回流比为4.2时,塔釜水合肼产品的质量分数可以达到20%以上。
On the basis of the kinetics data, an equilibrium model of reactive distillation process of non-catalytic hydrolysis reaction is established. The existing hydrazine hydrate process by acetone azine hydrolysis is optimized and simulated using Aspen Plus. The effects of column stage, feed location and reflux ratio (R) are studied. The optimal process parameters are shown as follows:25 of theoretic stages of the reactive distillation column,5 of the feed stage of supplement water, 10 of the feed stage for mixed materials of acetone, nitrogen and water, 1 of the molar ratio of water and mixture of acetone and nitrogen, and 4. 2 of the suitable R. Under the optimal condition, the mass concentration of hydrazine hydrate in the tower can reach 20% and even higher.
