The Effect of Salt, Alcohol and Surfactant on Optimum Middle Phase Composition
In this work, salt, alcohol and surfactant effects are investigated, at different water-to-oil ratios to determine their influence on phase behavior. A linear relationship is found between the logarithm of water-oil ratio in the middle phase and the salinity. Moreover, in the middle of the range of salt or alcohol concentration giving a three-phase system, the water-oil ratio in the middle phase has a value close to unity (value defined as an optimum), whatever the overall water-oil ratio may be.
