In the field of chemical engineering separation processes, such as extraction or distillation of heteroazeotropes, severe problems exist in phase separation of oil/water dispersions containing very small droplets. This is expecially true if the bulk phases contain surfactants stabilizing the interface and thus inhibit coalescence. The present work was aimed at investigating a novel technique of phase separation due to “membrane coalescence” for various emulsions stabilized by diverse surfactants in order to clarify the performance as well as the operational limitations.
