提出一个新的计算非理想多元元精馏物系Murphree点效率的方法，在计算塔板上鼓泡液体中汽液两相间的传质通量时，充分考虑了在扩散路径上混合物组成的变化所产生的影响，同时根据多相湍流动力学的原理计算了鼓泡液体中汽、液相的接触面积．利用这个新模型对6个多元非理想混合物的计算，表明它能够准确地预测某些组元点效率的奇异性，而且预测的精度明显地优于现有其他方法，证明它是一个有效的、可靠的非理想多元精馏点效率预测方法.
A new method to calculate the Murphree point efficiency of non-ideal multivariate distillation system is proposed. When calculating the mass fluxes of vapor-liquid two-phase in the bubbling liquid on the plate, the composition of the mixture in the diffusion path is fully taken into account The contact area between vapor and liquid in bubbling liquid is calculated according to the principle of multiphase turbulence dynamics. Using this new model for the calculation of six multivariate non-ideal mixtures, it shows that it can accurately predict the singularity of the efficiency of some component points, and the prediction accuracy is obviously superior to other existing methods to prove that it is an effective, Reliable non-ideal multiple distillation point efficiency prediction method.
