Abstract
The invention concerns a continuous mixing device (1) having a rotating shaft (4) fitted with blades (7, 7a). The mixture obtained at the outlet from the mixer results from admitting to the mixer a high-viscosity fluid (22) and at least one fluid of a lower viscosity. The mixing device is suitable for providing a mixture of lower viscosity compared with the most viscous fluid admitted at the inlet (2, 38) of the mixer. The invention provides a method of pumping a viscous fluid and use of the mixing device in an installation for pumping a high viscosity crude oil. FIG. 1 to be published.
