- W2360872531 abstract "The present paper aims to introduce the results of our risk analysis based on the HAZOP vector chain.As we know,conventional risk analysis of HAZOP is only focused on the single corresponding relationship between the cause-deviation-accident and the processinvolved parameter,but disregard of the mutual relationship between deviations of polytechnic parameters themselves,even neglecting the relationship between deviations and their resultant accidents in a large complicated production system.Therefore,it is difficult to recognize the accident process caused by the deviations of deeper and more complicated nature.To deal with the consequences caused by using the conventional HAZOP method,this paper has proposed an innovated risk analysis method of vector chain based on HAZOP,which can be used as an auxiliary quantitative tool in the HAZOP process.On the basis of the routine HAZOP study,we have constructed a vector diagram and vector chain diagram by joining deviations with vectors into a system.It is due to the establishment of vector chain diagram that has made it possible to evaluate the weight of a vector chain in the entire diagram and select the optimal strategies accordingly.A chemical case study on trichloro-acetone process has enabled us to make out and display the effectiveness of vector diagram based HAZOP analysis method and in turn to recognize the logical relationship and related weights among the deviations themselves and among the deviations and the resultant accidents and prioritize the vector chains on the basis of their risk values and control more important vector chains in order to improve the process safety effectively." @default.
