For gas mixtures

For gases with contents of compounds with higher molecular weight, the curve is shifted significantly to lower pressures. For gas mixtures without hy-... 

The parameters A, B, and C are dependent on the particular nature of the gas. Katz developed a simple method for gas mixtures that takes the composition of the gas into account [942,1086]. Furthermore, a graphic method is available that permits the estimation of the hydrate-forming temperatures at pressures for natural gas containing up to 50% hydrogen sulfide [129]. 

One word of caution For gas mixtures or air, be sure to include the contained water. It can be a healthy percentage for a Gulf Coast air compressor. 

For gas mixtures, the partial pressure is defined as the pressure that would be exerted if that component alone occupied the volume of the mixture. Thus, for an ideal gas,... 

Another computational model for the removal of nitrogen oxides in a pulsed dielectric barrier discharge was developed by Gentile and Kushner [75] for gas mixtures containing N2/02/H20 (85 5 10) and 500ppm NO. The results show that NO concentration decreases relatively fast in time, whereas the densities of the reaction products (HNOz,...

For gas mixtures, the ratio Pr/Sc is about 0.2-5. AH/pcpg is normally large. It follows that a small value of AC corresponds to a large value of AT. Generally, the boundary film does not offer much resistance to mass transfer, except in relative terms during the...

Under the reasonable assumptions of zero expansion and negligible pressure drop, the model of Smith for gas mixture eq. (5.379) is also applicable. 

Evaluate the theoretical conversion of sulfur dioxide by using the model derived for gas mixture in trickle beds. Check if the assumptions of the model are met. 

All of these equations have some utility however, none is particularly accurate as pressure and temperature approach the critical point. Also, those equations were formulated for pure substances. Arbitrary mixing rules must be used to determine values of constants a and b for gas mixtures. 

The constants for these equations have been derived experimentally from data for pure gases. However, the equation can be used for gas mixtures by combining the constants using the following mixture rules.

Estimating solubility products for pure gas hydrates as outlined above is fairly straightforward. Application of this model to real-world situations is, however, generally more complicated because gases in natural environments are seldom pure gases. There are a number of models that can be used for gas mixtures (Duan et al. 1992a,b Pitzer 1995). In this work, we assume that... 

For gas mixtures, the preferred way of expressing the composition is in mole fraction (mol/mol), and it is calculated by the following equation ... 

These fluctuations, which are referred to as order-parsmeter fluctuations in studies of critical phenomena (3). comprise the driving forces for transport in the system. For liquid mixtures near a critical mixing point, the order parameter is concentration, and for pure gases near the vapor-liquid critical point, the order parameter is density. For gas mixtures such as supercritical solutions near the critical line, the order parameter is again density, which is a function of composition and temperature compared to a pure gas where density is a function of only temperature at constant pressure.

Basically there are two different conventional Claus processes, the straight-through process and the split-flow process. For gas mixtures containing 50-100 mol-% H2S the straight-through process is recommended, for the other mixtures the split-flow process is more appropriate. Both processes will be treated in some more detail below [2], Several modifications to the original Claus process have been developed in the mean time. One of them, the Superclaus process is also treated below, for other variations on the conventional process, the interested reader is referred to [2],...
