Incipient flooding
Webchempedia.info WebIncipient flooding begins when liquid is entrained with the rising vapour and reaches the tray above. If the downcomers have the capacity to handle both the entrained liquid plus the normal liquid flow, then fractionation will suffer but the column will be operable. ...
