DST-27 Effects of Sealing on Downcomers

Traditional Research Idea

Expected Benefit toMembers: Improved operability know-how. Present Situation and Proposed Research: Find out what conditions a dynamic seal might work allowing for dc clearance to be greater than outlet weir height or to eliminate the outlet weir which would help in fouling services. Proposed Internals and Test System: What happens to tray operation if the dc panel is not completely sealed at the clamping bar – something that may happen during a revamp and retrofitting non-conventionally shaped downcomers to straight downcomer bolting bars using an adapter that may not attach firmly to the bolting bar. Estimated Unit Time: Unknown. Estimated Additional Costs (Beyond Unit Time): Unknown. Background and Discussion: None.
