Distillation Tray Efficiency: oconnell_correlation
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 | alpha mu (dimensionless) | notes | overall efficiency pct (pct) | unit | value typical |
|---|---|---|---|---|---|---|
| oconnell_correlation | alpha_mu_0.02 | 0.02 | O'Connell overall column efficiency; formula: Eo=50.3*(alpha*mu)^-0.226; alpha=relative volatility of key components at feed conditions; mu=molar-average liquid viscosity (cP) at average column conditions; valid range alpha*mu = 0.1–10; at alpha*mu<0.1 formula extrapolates above 100% — capped at 100% per engineering practice | 100 | pct | 100 |
| oconnell_correlation | alpha_mu_0.05 | 0.05 | O'Connell correlation; formula Eo=50.3*(alpha*mu)^-0.226 = 99.0% at alpha*mu=0.05; near upper validity boundary | 99 | pct | 99 |
| oconnell_correlation | alpha_mu_0.10 | 0.1 | O'Connell correlation; lower bound of primary validated range (alpha*mu 0.1–10) | 84.6 | pct | 84.6 |
