Fluid catalytic cracking (FCC) is one of the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling and high-molecular weight hydrocarbon fractions of petroleum crude oils to more valuable oil products. The purpose of this study is to verify the structural integrity of integrated system including reactor, regenerator and catalyst standpipes which are the core facilities of FCC. The fundamental process design of FCC is provided by licensor and the details of reactor and regenerator are designed by using an in-house program based on the ASME Sec.Ⅷ, Div.1. To get more conservative results, a variety of load conditions such as dead weight, pressure, thermal expansion, seismic and wind loads are applied in the structural strength assessment. The structural piping analysis considering the latest design specification of the specific vendor items like expansion joint, slide valve and spring hanger is performed and its result is provided to the related vendors to confirm their performance once more. From the comprehensive analysis results, it is concluded that the analyzed system is designed to have sufficient flexibility to prevent pipe movements from the elastic failure due to the overstress of the pipe components or anchors. The analysis results meet the requirement of all applicable design codes and licensor’s specification.
