New prediction of Murphree efficiency for distillation tray operating under entrainment condition
A new empirical correlation has been presented for the effect of entrainment on distillation tray efficiency based on the results of numerical solution given by Lockett, et al. The calculated results are in good agreement with those of the numerical solution given by Lockett, et al. The average devi...

| Summary: | A new empirical correlation has been presented for the effect of entrainment on distillation tray efficiency based on the results of numerical solution given by Lockett, et al. The calculated results are in good agreement with those of the numerical solution given by Lockett, et al. The average deviation is 1.14% and the maximum deviation is 4.76% for the ranges of 0 〈 Pe ≤ 1000, 0.40 ≤ EOG ≤ 1.00, 0.5≤λ0 ≤ 3.0 and e0 ≤ 0.3. In comparison with the correlation proposed by Bennett et al., the average and maximum deviations of EM^av are 2.17% and 20.49%, respectively. |
