Incipient flooding
WebNov 23, 2010 · The Flooding Predictor™ works by detecting the incipient flood point and controlling the column closer to its actual hydraulic limit than historical practices have allowed. Further, the technology uses existing column instrumentation, meaning no additional refining infrastructure is required. WebApr 1, 2024 · Subsequently, these curves reach some asymptotic values of critical u ¯ zg, which implies the effects of diameter on incipient of flooding are significantly weakened. Diehl and Koppany (1969) pointed out that there was a critical size (diameter) beyond which the flooding velocity was independent on tube diameter.

WebTypically, at a high water flow rate, several different air flow rates would be used, the last corresponding to incipient flooding, i.e. to a large hold up of water on the packing. During these runs the water exit line should be adjusted to give minimal water level in the column bottom, say 2 to 4 cm. 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. ...
