HAZOP analysis technology for in-service diesel hydrogenation unit

Diesel hydrogenation unit is ranked the first in fire grade.It is necessary to identify the risk and evaluate the safety rank in order to ensure the work safety and realize the early prevention of accidents.The hazard and operability（HAZOP） analysis method is a widely used tool for the hazard identification and analysis in the process industry,which has many advantages,such as good systematicness and completeness,and so on.Firstly,the origin and application of HAZOP method were introduced.Secondly,the difficulties of HAZOP analysis for in-service unit were explained in detail,and the corresponding suggestions were put forward in this paper.Then,the process of HAZOP analysis for in-service unit was presented.Finally,HAZOP analysis for in-service diesel hydrogenation unit in a PetroChina petrochemical company was carried out as a study case,in which the safety pitfalls and potential hazard were identified.As a result,the necessary precautionary measurements and reasonably recommendations were proposed for the potential pitfalls of higher risk level.The results showed that HAZOP analysis is an effectively measurement for improving the safety of in-service unit,and it can provide the reliable basis for the safety management of the unit.
