【摘要】 光气合成过程是高危工艺,原料氯气为剧毒化学品,一氧化碳为高毒化学品,产物光气为剧毒化学品,在储运、使用过程中发生泄漏后,造成中毒、燃烧、爆炸等事故。针对光气合成的工艺过程,用HAZOP方法分析了工艺参数发生偏离设计的情况,找出了偏差发生的原因和导致的后果,提出了针对性的安全建议措施;用ALOHA模拟重点分析了既有燃烧爆炸又有中毒特性的一氧化碳发生泄漏后不同温度、风速引起的警戒范围、喷射火引起的燃烧范围。更多还原

【Abstract】 Phosgene synthesis process is a high-risk process, because raw material chlorine gas is a hyper toxic chemical,carbon monoxide is a highly toxic chemical, and the product of phosgene is a hyper toxic chemical. In the storage and transportation, poisoning, combustion, explosion and other accidents are resulted in use of the process of leakage. In view of the process of phosgene synthesis, using the HAZOP method, the deviation of process parameters from the design was analyzed, the cause and consequences of deviation were found out, and targeted safety measures were put forward. By ALOHA simulation, the combustion range caused by different temperatures, wind speed and fire after carbon monoxide leakage was focused on analyzing, both combustion explosion and poisoning characteristics.更多还原
