The HAZOP Analysis In Delayed Coking Unit

HAZOP analysis is a structured risk analysis tools, can be comprehensive, systematic identification process in danger and to improve operations, reduce management blind spots, and effectively improve the efficiency and productivity of the workflow. The HAZOP analysis focused on analyzing abnormal operating conditions and things that had never happened before, are an important complement to the design and operation of. HAZOP analysis maturity HAZOP analysis side has also been a large improvement in Europe and the United States and other Western countries, relatively clear legal support. However, HAZOP analysis application in industrial installations late start legal support is not perfect.Delayed coking unit was completed on May10,2003, June1,2003a car, the device in July2005of1.3million tons/year expansion transformation, from the building, and started the transformation process were not carried through the system risk analysis and identification, bring greater threat to the delayed coking unit safe and stable production. To this end, the Jilin Petrochemical Company decided HAZOP analysis method to conduct a comprehensive analysis of the delayed coking unit to improve the device intrinsically safe. By delayed coking unit HAZOP analysis of proposed measures to curb153contains interlock protection, alarm settings, reverse flow protection11aspects. Delayed coking unit are carried out to implement the recommendations made in the HAZOP analysis, through the implementation of the proposed measures, and ultimately achieve the target to improve the device safe and stable operation level.
