Models for gas-liquid and gas-liquid-solid systems, listed in Table 5.4-8 at the end of Section 5.4.3, are limited illustratively to a simple irreversible reaction between a pure gaseous reactant A and a non-volatile liquid reactant B ... 

Gas chromatography makes use, as the stationary phase, a glass or metal column fdled either with a powdered adsorbent or a non-volatile liquid coated on a non-adsorbent powder. The mobile-phase consists of an inert-gas loaded with the vapourised mixture of solutes flowing through the stationary phase at a suitable temperature. In the course of the passage of the vapour of the sample through the column, separation of the components of the sample occurs in two ways, namely ... 

The liquid-phase mass balance (3.368) is used for non-volatile reactants that are present in the liquid-phase. This mass balance is called non-volatile liquid-phase mass balance (Hopper et al., 2001). 

The mobile phase in vapour phase chromatography is a gas (e.g. hydrogen, helium, nitrogen or argon) and the stationary phase is a non-volatile liquid impregnated onto a porous material. The mixture to be purified is injected into a heated inlet whereby it is vaporised and taken into the column by the carrier gas. It is separated into its components by partition between the liquid on the porous support and the gas. For this reason vapour-phase chromatography is sometimes referred to as gas-liquid chromatography. 

In FAB, the sample is usually dispersed in a non-volatile liquid matrix, such as glycerol or diethanolamine, and deposited at the end of a sample probe that can be inserted into the ion source. The sample on the probe is ionised when bombarded by the fast atom beam. However, ionisation of the matrix also occurs, leading to a very large background signal. The technique is thus limited for the analysis of small molecules. Fast-moving ions (Cs+ or Ar+) can be used instead of fast-moving atoms, which is the basis of a technique called liquid secondary ion mass spectrometry (LSIMS). 

Since in the critical point the bubble point curve (l+g—tf) and the dew-point curve (l+g-+g) merge at temperatures between 7C and 7 , an isotherm will intersect the dew-point curve twice. If we lower the pressure on this isotherm we will pass the first dew-point and with decreasing pressure the amount of liquid will increase. Then the amount of liquid will reach a maximum and upon a further decrease of the pressure the amount of liquid will decrease until is becomes zero at the second dew-point. The phenomenon is called retrograde condensation and is of importance for natural gas pipe lines. In supercritical extraction use is made of the opposite effect. With increasing pressure a non-volatile liquid will dissolve in a dense supercritical gas phase at the first dew point. 

All these equations reduce to their dilute-system equivalents as the inert concentrations approach unity in terms of mole-fractions of inert concentrations in the fluids. In dilute systems, the logarithmic-mean insoluble-gas and non-volatile-liquid concentrations approach unity. 

For detn of combustion of solid and non - volatile liquid materials, the most convenient method is to use a "closed bomb calorimeter . 

Several years ago, a novel sample preparation technique was developed (10) for sputtering Intact organic molecules from surfaces. The key feature of the technique Is the use of a viscous, non-volatile liquid surface from which to sputter and generate organic secondary Ions. 

The following developments will be restricted to laminar liquid flow with weak gas-liquid interactions. However, this is not a limitation of the proposed methodology which could be easily applied to any other flow regime. Applications will be presented for the modelling of the irrigation rate, the dynamic liquid holdup and the apparent reaction rate in the absence of external mass transfer limitations and in the case of non volatile liquid reactants (i.e. approximatively the operating conditions of petroleum hydrotreatment). 

Both the mutual solubility of the coexisting liquid and supercritical gas phases and the density of carbon dioxide are the most important parameters in influencing interfacial tension in systems with both a non-volatile liquid and a supercritical component. 

Using a non-volatile liquid reactant would of course considerably limit the number of possible reaction steps and, in the fitting of the model, this would eliminate possible cross correlations between the values which the model enable to calculate.
