【摘要】 以降低环氧丙烷生产中的蒸汽消耗和提高皂化塔塔顶出料中环氧丙烷含量为目的,利用ECSS软件对氯丙醇皂化塔的用能情况进行了分析,通过模拟不同回流比、进料位置、操作压力下塔的耗能的情况,得出皂化塔的最优操作条件,在塔顶出料中环氧丙烷摩尔含量基本不变的情况下,新鲜蒸汽的消耗量降低了63．3％,从而达到了降低能耗的目的。更多还原

【Abstract】 In order to reduce the vapor consume and enhance the content of the propylene epoxide at the top of the saponification column, we use the software of ECSS to analyse the energy using of propylene epoxide saponification tower. By simulating the results of different reflux ratio, the feed location, the pressure of column we get an optimum operational condition of the column. At the optimum operation condition, the steam use consume reduced 63.3 % and at the same time the propylene epoxide content at the top of the saponification column is about the same as the result of before condition.更多还原
