Distillation Tray Efficiency: tray_performance_data
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, tray spacing recommendations, and measured tray efficiency data from Perry's Table 14-12 (29 pilot/plant measurements for sieve and valve trays across various systems)
