Effect of Entrainment on Distillation Tray Efficiency with Vapor Complete Mixing and Liquid Partial Mixing

提出了文题的液体混合池模型并导出了相应的数学关系式,其计算结果与Lockett等给出的数值解相当吻合,而计算过程较为简便。

A new form of mixing pools model was presented and the methematical correlations were derived, taking into account the effect of entrainment on distillation tray efficiency under the conditions of complete mixing of the vapor and partial mixing of the liquid. The calculated results are in good agreement with those of numerical solutions given by Lockett et al. The correlations proposed are more convenient to use. For limiting cases(e_0=0; n=1; n=1 and λ_0=1), the present correlations can be reduced to equations identical with those published in the literature.
