Abstract
Recently, due to the rising of oil prices, interest in FCC Unit (Fluid Catalytic Cracking Unit) energy recycling is increasing. FCC Unit (Fluid Catalytic Cracking Unit) is a mechanical used to convert bunker C oil into high quality gasoline. Pressure vessel of FCC Unit is that refining the crude oil when is operating in high-temperature and high-pressure environment. So it needs analysis of structure carefully. In this paper, FEA (Finite element analysis) of the FCC unit was performed to evaluate its structural stability and weight reduction. The equivalent stress of the FCC unit was investigated and compared against the ASME code design specifications. The area of high stress concentration with maximum stress higher than the prescribed value was analyzed locally to carefully evaluate the stress. Finally, we were reduces the thickness of the CA nozzle in FCC unit, and it was satisfied structural stress.
