一种新型危险化工工艺安全评估方法的设计

Design of a new method for safety assessment on dangerous chemical process

在安全生产过程中,建设项目风险评价在我国经过几十年的发展,无论在模型亦是方法上均有所进步,但对化工项目进行危险化工工艺风险等级评价的研究并不多见。本文按照危险化工工艺表征涉及的影响因素,在参考了日本劳动省"六阶段"的定量评价表以及危险度评价法并对15种危险化工工艺定性分析的基础上,提出了一种基于危险度评价法的更为全面的危险化工工艺辨识方法。该评价方法可用于确定危险化工工艺的风险等级。为化工企业工艺危险的实时评估和安全管理提供技术支撑和科学途径。

With the development of chemical technology,process safety in the safety production is an important part of chemical safety production.In more than a decade in China,risk assessment of construction program has been improved in terms of either models or methodology.However,there are few studies on risk rank assessment for dangerous chemical process.On the basis of the ＂ Six phase＂ quantitative evaluation coming from the Japanese Ministry of Labour and the risk assessment method,a more comprehensive risk identification method for chemical processes was proposed in order to quickly and easily assess the risk of chemical process risk level.This model would give assistance to real-time process risk assessments and corresponding management,and also provide help and scientific way for the government in the safety management of dangerous chemical process.
