Study on Application of LOPA in HAZOP on China Refinery Design

Recommending the demand of HAZOP and LOPA evaluation method in the design stage from China department of work safety and large scale petroleum enterprises, summarized the feature and analysis process of HAZOP and LOPA, obtained the complementary by comparing the advantages and disadvantages, put forward the feasibility about comprehensive assessment of the two tools. With the example of refinery RDS unit which is in basic design stage, briefly stated the process about comprehensive assessment of the two tools, and verified the feasibility and advantages of comprehensive assessment of the two tools. Affirmed the advantages and put forward shortages of comprehensive evaluation of the two tools through analysis theory and project case. Suggested to continuously improving the analysis process in design stage to make it more adapted to the design of domestic project, improve safety design integrity of the domestic design institutes, protect the device to more steady and safely。
