Weeping in a Distillation Column

When the vapor rate is low, liquid is allowed to flow through the tray holes before mixing with the vapor. To learn more about weeping, the trays that can prevent it, and other types of tray designs, please visit AIChE’s Distillation Technology for Operators course at www.aiche.org/ela113

Great

"counter flow trays weep as part of the design

How do you prevent weeping?

[@ollieq5259]

Ensure the vapour velocity is above the minimum.

[@doughboi007]

I would imagine the weeping slows when you have a higher reboiling vapor flow rate that flows up to the top.
