Studies in Vapour-Liquid Equilibria
… work, involving both the determination of vapour-liquid equilibrium data for acetic acid systems, and theoretical work, including the development of data reduction programs, has been carried out. The practical work involved modification of the feed and pressure systems of a modified Cathala …

Vapour-Liquid Equilibria within Nanoporous Media
This thesis is dedicated to the exploration of fluid phases confined in nanoporous materials using Nuclear Magnetic Resonance (NMR) techniques, with an aim to benefit catalysis research. Included in this report are studies of pure fluids and their mixtures, confined in titania and silica catalyst …

Vapour-Liquid equilibria at Low Concentration of One Component
… a total pressure apparatus to acquire isothermal vapour-liquid equilibrium data for binary mixtures. The method has been demonstrated to be capable of producing up to 30 data points from one experimental run and provide data at very low concentrations of one component (< 10-4mole fraction). A …

Vapour-liquid equilibrium studies at atmospheric to moderate pressures
A study of vapour-liquid equilibria is presented together with current developments. The theory of vapour-liquid equilibria is discussed. Both experimental and prediction methods for obtaining vapour-liquid equilibria data are critically reviewed. The development of a new family of equilibrium …

Phase equilibrium studies at moderate pressures
The theory of vapour-liquid equilibria is reviewed, as is the present status or prediction methods in this field. After discussion of the experimental methods available, development of a recirculating equilibrium still based on a previously successful design (the modified Raal, Code and Best still …

Organic fluid mixtures as working fluids for the trilateral flash cycle system
… used which leaves the expander as dry saturated vapour. A binary mixture of hydrocarbons was therefore sought which by variation of the constituent proportions, would satisfy this requirement for a range of inlet temperatures when the condensing temperature is constant. Methods of estimating …

Models of gas-liquid solubilities
A recent method for phase equilibria, the AGAPE method, has been used to predict activity coefficients and excess Gibbs energy for binary mixtures with good accuracy. The theory, based on a generalised London potential (GLP), accounts for intermolecular attractive forces. Unlike existing prediction …

A Novel Technique for the Separation of Dilute Butanol from Aqueous Fermentation Broths
… would be required for the process. The equilibria of butanol and side-products with C4 – C5 hydrocarbons were investigated using vapour-liquid equilibria and excess enthalpy measurements from the literature. Models of the extraction and distillation processes were then built using these …

The SSIP approach to solvation
… of the surface site interaction model for liquids at equilibrium (SSIMPLE) which uses the SSIP description for molecules to calculate free energies. Functional Group Interaction Profiles (FGIP) describe the energy change of two solute SSIPs interacting as a function of solute SSIP values. …

The vertical flow centrifugal gas-liquid separator and its application to the removal of gases from geothermal wells
Two vertical flow centrifugal gas-liquid separators were designed, built and tested using steam-water and air-water mixtures as the two-phase fluids. The theoretical analysis of the vertical flow centrifugal gas-liquid separator and the experimental data from the model separators is given in this …

Thermodynamische Untersuchungen von Phasengleichgewichten in komplexen Systemen mit assoziierenden Komponenten
… equipment for measurement of precise isothermal vapour–liquid equilibria (VLE) using the dynamic method was developed. The pool of experimental data for cyclohexylamine was extended significantly. Isothermal VLE were measured in 3 binary and 4 ternary systems, liquid-liquid equilibria (LLE) were …
