两种风险评价方法在浅冷装置评价中的对比

Comparison of Two Risk Assessment Methods in Natural Gas Shallow Freezing Unit Assessment

从原理和评价程序两方面对比了道化学火灾、爆炸指数评价法和化工厂危险度评价两种定量风险评价方法。将两种方法应用于天然气浅度冷冻处理装置,分别评价后进行各单元风险排序,两种方法的结果可以较好的吻合。讨论了对比的结果,为现行的风险评价方法之间的对比提供了依据。

Two quantitative assessment methods,Dow Chemical Company Fire & Explosion Index Method and Chemical Plant Risk Degrees method are compared from the view of both element and assessment procedure in this paper. And these two methods are used to evaluate natural gas shallow freezing unit, result are given after assessment. The risk sequencing is consistent with each other according to the results. The result of comparison is discussed,and it can provide evidence for comparison between different current assessment methods.
