For those refinery engineers with Delayed or fluid cokers, I'm interested in basis used for releif evaluations from main fractionator. The Sengupta and Staats approach leads to relief rates in excess of normal drum vapor rate (plus emergency steam). While this approach has technical merit, it leads to oversized relief valves for a variety of reasons (esp. drum self quench). Using the drum rate alone, discounts the potential impact of column liquid hold up considered by Sengupta and Staats.
Has anyone pursued rigorous reconcilliation of Sengupta/Staats with real performance by either dynamic simulations, or other analysis?
