Abstract
Apparatus for use in the treatment and recovery of viscous petroleum emulsions comprises a leaktight chamber in which a reduced pressure is established, the chamber having an inlet connected to a feedpipe for sucking up emulsion. A mixer is connected on the feedpipe and a demulsifier is supplied to the mixer simultaneously with the emulsion so that the emulsion mixed with demulsifier is fed to the chamber.
