Abstract
An oil in water emulsion is prepared as a continuous process by causing a stream of water to flow through a duct containing a Venturi providing a converging frustum of a cone zone, a diverging frustum of a cone zone and a central zone joining the two frustum of a cone zones, so that the stream flows through a zone upstream of the Venturi where it is directed along a helicoidal path through the converging frustum of a cone zone to the central zone, drawing oil for emulsification to the duct at the zone upstream of the Venturi and causing it to flow along a helicoidal path in the same direction as the water to the central zone so that the oil and water mix and emulsify in that central zone, causing the emulsion so formed to flow through the diverging frustum of a cone zone, then causing the emulsion to flow along a helicoidal path of reverse slope, and thereafter discharging the emulsion from the duct.
