Distillation Tray Efficiency: approach_to_flood
Distillation tray efficiency data: O'Connell overall column efficiency vs alpha*mu (14 data points, formula Eo=50.3*(alpha*mu)^-0.226), Murphree tray efficiency ranges by tray type and system, weep-point velocities, Fair flooding C-factors (Csb) at multiple tray spacings, downcomer backup limits, tray pressure drop components, turndown ratios, and tray spacing recommendations
| parameter type | record id | notes | system description | tray type | unit | value max | value min | value typical |
|---|---|---|---|---|---|---|---|---|
| approach_to_flood | design_basis | Standard design at 80-82% of flooding velocity for non-foaming systems; 70-75% for foaming tendency; 85% maximum for well-established non-foaming systems; used with Fair flooding correlation | Design approach to flood percentage | sieve | pct_flood | 85 | 75 | 82 |
