Fractionation of Binary Mixtures
2017Based on the mass balance and the vapour–liquid equilibrium, the number of necessary stages for the separation and the required reflux ratio are determined using graphical and calculation methods. A shortcut method is given for a quick estimation. The influence of the thermal condition of the feed product on the separation and the column loading is ...

SEVERAL attempts have been made to represent the viscosity,, of a mixture, as a function of the concentrations, c1 and c2, and the viscosities, 1 and 2 of the components. So far as we are aware, all investigators (with the exception of Dolezalek) have used the general form: with various expressions for f, such as f = log (Arrhenius), f = 1/ (Bingham ...

IN a recent communication1, Mr. A. J. A. van der Wyk has presented a new formula for the calculation of viscosity of binary mixtures. I would point out that this problem has already been fully solved in two ways. On the base of thermodynamical considerations, the formula2 has been found, where denotes the viscosity of the mixtures, m1, 1, m2 and 2 the ...

Abstract The effect on the ordinary coefficient of diffusion of the mobilities of two interdiffusing, non-ionic components is evaluated by a straightforward application of the equations of irreversible thermodynamics along the lines suggested by De Groot [1].

Experimental results are presented for convection in shallow layers of binary mixtures heated from below. We used both ethanol-water mixtures at room temperature[1,2] and 3He-4He mixtures at 2.2 K.[3,4] The primary difference between the two cases is the value of the Prandtl number σ, which is about 18 in the room-temperature system and about 0.6 in ...
