Study on Performance-based Safety Design of Chemical Facility Layout

At present, the design of chemical facility layout is always based on kinds of indicated codes, e.g. GB50160-2008 and GB50016-2006. There are many shortcomings of these codes, such as inflexible, lacking of comprehensive safety theory and ambiguous when applying to extra-large scale chemical plant and pilot plant. A performance-based framework was built for the safety design of chemical facility layout, which contains four key components: hazard identification, performance target confirmation, consequence assessment and defending effect evaluation. As the most important component of the framework, performance target confirmation was analyzed in particular, and a confirmation method was proposed through matching accident scenario and acceptable damage level of chemical facility.
