ABSTRACT:
A method and a device for dehydrating a heavy oil wherein an emulsion of water and a heavy oil is mixed in a stirring chamber together with a suitable amount of an emulsion breaker, the mixture is subjected to separation in a two-phase separation tank to a heavy oil-rich component and a water-rich component, the heavy oil-rich component is then fed to a dehydrator of a high voltage charge type in which separation to a dehydrated heavy oil and a water-rich component is effected, the water-rich component fractions supplied from the two-phase separation tank and the dehydrator are mixed in a pipeline, the mixture thus obtained is admixed with an O/W emulsion breaker and then, fed to a stirring chamber and finally separated to a heavy oil-containing component and a heavy oil-free water layer in a second separation chamber.
