Vibration Analysis of a Large Pressure Vessel Using the FEA

Abstract:

According to the recent rise in oil prices, interest in FCC Unit (Fluid Catalytic Cracking Unit) energy recycling is increasing. Such FCC Unit is a facility which refining low-valued bunker C oil into high-valued gasoline. Pressure vessel that refines crude in FCC Unit needs various interpretation because it operates under high-temp and pressure. Our concern about this FCC Unit is increasing. Experiments about its safety is not enough. In this paper, whether FCC Unit has structural stability or not, we found out FEM(Finite Element Method) analysis after trying 3D modeling by using FCC Units condition of design and critical stress as a translating data. First, we researched the safety of structure applying external factors using the natural frequency. The structure is safe from modal analysis result, the first natural frequency is 13.614Hz , beyond the of the frequency range of the wind (0.001~8Hz) and earthquake (0.1~10Hz).
