Nonreactive binary mixtures

It has already been pointed out that the equations of change are valid for describing turbulent flow. The diffusion of A in a nonreacting binary mixture is described by the equation of continuity ... 

For simplicity, we shall again employ assumptions 1-5 of Section 1.3, the hypotheses of steady, low-speed flow, and assumptions 1-4 of Section 3.1.2. The other assumptions in Section 1.3 are not necessary here because we are studying a binary, nonreacting gas mixture and are not considering... 

Mixtures of only He, N2, and CO2 were tried in real FAIMS work so far, and compositions involving other gases will likely improve many existing and future applications. An ideal FAIMS buffer would (i) be a binary mixture of gases that form very dissimilar potentials with ions of interest, (ii) resistelectrical breakdown, and (iii) as a practical matter, be chemically inert and comprise stable, mutually nonreactive, readily available, and not too costly components. To avoid condensation and facilitate...

If the liquid mixture is extremely non-ideal, liquid phase splitting will occur. Here, we first consider the hypothetical ternary system. The physical properties are adopted from Ung and Doherty [17] and Qi et al. [10]. The catalyst is assumed to have equal activity in the two liquid phases. The corresponding PSPS is depicted in Fig. 4.5, together with the liquid-liquid envelope and the chemical equilibrium surface. The PSPS passes through the vertices of pure A, B, C, and the stoichiometric pole Jt. The shape of the PSPS is affected significantly by the liquid phase non-idealities. As a result, there are three binary nonreactive azeotropes located on... 

The theory describing diffusion in binary gas mixtures at low to moderate pressures has been well developed. Modem versions of the kinetic theory of gases have attempted to account for the forces of attraction and repulsion between molecules. Hirschfelder et al. (1949), using the Lennard-Jones potential to evaluate the influence of intermolecular forces, presented an equation for the diffusion coefficient for gas pairs of nonpolar, nonreacting molecules ... 

This resistance is larger when convective mass transfer is negligible relative to diffusion, and V is insignificant. Under these conditions, and the mass transfer resistance simplifies to 1/23ab- If convective mass transfer is important in a nonreactive mixture of n components which can be treated as a pseudo-binary, then ... 

Generating residual curve maps We go back to reaction R3 and assume a temperature-independent value oiK=2. We also assume that A has a constant volatility relative to R of 5, and B a relative value of 3. The first step is to generate the RCM for the nonreactive mixture of A, B, and R. This is just a triangular plot of the binary liquid phase compositions AB, BR, RA. The procedure consists of the following steps ...
