The coalescence of droplets was studied to elucidate the process of demulsification by using the apparatus based on Cockbain and McRoberts method. Hydrocarbons were used as oil phase and their droplets in water containing SDS were formed by rapid injection from capillary. The processes of coalescence were studied by the height of droplet column. The coalescence processes of the emulsion formed by the same samples were studied. The correlations between the coalescence of droplets and that of emulsions were found to be the same behaviour. Furthermore the droplets of coconut oil in the gum acacia solutions were also examined.
