Creep Analysis Using MPC Project Omega

Performing state-of-the-art creep damage calculations to determine the Fitness-For-Service of a variety of high temperature components including FCC vessels and piping, furnace tube sheets and tube hangers, and other process vessels.

Finite Element Stress Analysis Model of HK-40 Tube Sheet and Creep Damage Plot. Creep analyses used an MPC Omega model to determine stresses and creep damage (regions in gray exceed 100% Creep Damage for one set of future conditions). The plant was provided an operating temperature time envelope that allowed them to set operating conditions (feed rates) that would result in the desired length of run. The results also indicated areas to focus inspection and repairs at the next planned outage.
