Based on the actual production process and production theory reasonable design scheme was developed. The status and role of ethylene oxide in the national economy was discussed in this paper. Furthermore, the produce methods, the principle of produce and process were also interpred. Material balance of the main equipments, such as: the mixer, the reactor, the absorb tower of epoxyethane, and the absorb system of carbon dioxide have been calculated. Calculation of energy balance for the epoxyethane reactor were also carried out. Equipment calculations and checking of the reactor were carried on detail. The parameters, types and materials of the equipments were confirmed. Based upon, the high purity epoxyethane rectifier was draw using CAD. Finally, correspond measures for the production process were given. KEY WORDS：epoxyethane；process；reactor；material balance。  目 录 TOC \o 1-3 \h \u HYPERLINK \l _Toc29571 第1章 引言 l _Toc13591 §1.1 MACROBUTTON AcceptAllChangesInDoc MACROBUTTON AcceptAllChangesInDoc 环氧乙烷在国民经济中的地位和作用 l _Toc17939 §1.2 MACROBUTTON AcceptAllChangesInDoc 环氧乙烷在国民经济中的地位和作用 l _Toc26474 §1.2.1 生产技术 l _Toc17969 §1.2.2 技术发展动向 l _Toc25194 §1.3 环氧乙烷的市场需求状况 l _Toc8518 第2章 工艺概述 l _Toc13429 §2.1 环氧乙烷的性质 l _Toc26942 §2.1.1 EO的物理性质 l _Toc6806 §2.1.2 EO的化学性质 l _Toc21794 §2.2 生产方法的评述及选择 l _Toc16559 §2.2.1 氯醇法 l _Toc22438 §2.2.2 直接氧化法 l _Toc17499 §2.3 环氧乙烷的生产原理 l _Toc28192 §2.3.1 氧化反应原理 l _Toc21269 §2.3.2 二氧化碳脱除原理 l _Toc10136 §2.4 设
