摘要/Abstract

摘要： 针对环氧乙烷在生产、储存、运输和使用环节中存在的安全问题，对环氧乙烷特殊的物理化学性质进行分析. 环氧乙烷化学性质非常活泼，易开环并释放大量热量，在空气中的爆炸极限浓度为3%~100%，引燃能最小只需0.06 mJ，易燃易爆. 结合其自身反应特性及易自聚、歧化或分解等特点，讨论了其在安全操作、化工设计中的注意事项，并提出了具体建议措施，包括相关装置布置方案设计、安全温度和压力设计、设备安全及紧急处理设计等，以期能提高环氧乙烷在生产、运输和使用过程中的安全性和可靠性，减少相关事故的发生.

Abstract: Ethylene oxide (EO) is an important intermediate in organic synthesis with a wide range of uses. The special physicochemical properties of ethylene oxide were analyzed for the safety problems of production, storage, transportation and use. EO had a very actively chemical properties, such as the molecule ring was easily opened which would release lots of heat. It is flammable and explosive as that the explosion limit was from 3% to 100% in the air, and the ignition was minimal only 0.06 mJ. The safety operation designs and matters needing attention had been analyzed and discussed along with its special physicochemical properties, reaction characters, easy to self-polymerize, disintegrate and decompose, etc., which was aimed to solve the security problems existing in chemical production processes. The specific suggestions were put forward to improve safety and reliability in it production, transportation and producing, including related device layout design, safety temperature and pressure design, equipment safety and emergency treatment design, etc., and it would lead to reduce the related accidents.

Key words: petrochemical technology, ethylene oxide, basic physical properties, intrinsic safety, design &, operation
