The issue of static liquid holdup concentration in packed towers
Thread Content
I would like to ask the experts: in the distillation process of a packed tower, are the concentrations of the static liquid holdup and the dynamic liquid holdup the same? If there is a discrepancy, how can the concentration of the static liquid holdup be determined?
The concentration of the dynamic liquid holdup changes with operating conditions, while the concentration of the static liquid holdup is the value at rest and is not necessarily the same each time.
If, during parking, the concentration at the top of the tower is 0.93 and the concentration at the bottom is 0.105, then the static liquid holdup concentration is the average of these two values, approximately 0.5 – is that what it means?
