Abstract: A device for dispersing a water-soluble polymer in powder form having a standard particle size of less than 1 mm, includes: a wetting chamber, a chamber for grinding and discharging the dispersed polymer with a horizontal axis of revolution, and a mechanism for connecting the wetting chamber to the grinding chamber in the form of an L-shaped tube. The upper and lower parts of the wetting chamber and the L-shaped tube have an internal surface with an identical surface tension (TS1). The cover of the wetting chamber has an internal surface with a surface tension (TS2) higher than the surface tension (TS1) of the internal surface of the upper and lower parts of the wetting chamber and the L-shaped tube.

Abstract: An installation for storing, metering, and dissolving water-soluble polymer particles, in particular for enhanced oil and/or gas recovery operations, includes a so-called “polymer dissolution” container A and at least one so-called “polymer storage and distribution” container B positioned upon container A. The bottom of container B and the roof of container A each have an opening facing one another allowing the passage of the polymer from container B into the supply mechanism of container A. The installation further includes a connection mechanism able to work with the polymer supply mechanism.
