Abstract :A reversed-micellar solution is defined as a system of water, oil and an amphilphile (surfactant). It has been shown that gas hydrate formation in reverse-micelle systems provides a means for in-situ control of the droplet size, which in turn can be used to manipulate the properties of any material that has been formed in the water droplet. In this study, the incipient conditions for ethane and carbon dioxide gas hydrate formation in the presence of AOT-water-isooctane were carried out. Subsequently, the results were modelled using the model of van der Waals and Platteeuw in conjunction with a model for the activity of water in reverse micelles and the Peng Robinson equation of state. The predictions were seen to fit the experimental data well.
