The device, which can be used for homogenising crude oil flowing through pipelines (1), comprises two substantially concentric tubes (2, 3) interconnected at one end by pumping means (5), the inner tube (2) having an inlet (8) at the other end projecting from the outer tube (3), and the outer tube (3) being closed at this end (9) adjacent to the inlet (8) and having a plurality of apertures (4) spaced along its length, whereby fluid can be drawn into the inner tube (2) through the inlet (8) and pumped out through the apertures (4) in the outer tube (3). The apertures (4) may be positioned (as shown Fig. 2) such that the liquid is pumped therefrom in a direction transverse to the axis of the pipeline (1). <IMAGE> |
