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 ...

Turbulent critical binary mixtures
Physics Letters A, 1984Abstract Turbulence suppresses the growth of critical fluctuations and prevents the progress of the phase separation in critical binary mixtures. The steady state structure factor I(k) is predicted to have a broad peak at k=0. Its peak maximum grows and its peak width decreases as the Reynolds number is decreased.

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 ...

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].

Methods to derive an interface concentration profile in a two component system are discussed on the basis of squared gradient theories. Starting point is the description of soft matter systems, where the correlation length of fluctuations becomes the relevant length scale. A phase diagram which contains bulk and interface phase transitions is used as a
