Claim 13:
14. A process for producing a water-soluble polymer solution using the installation that is the subject-matter of claim 1 and comprising the following steps:
water-soluble polymer in powder form is fed into polymer storage-only container C, or into polymer storage and distribution container B by a supply mechanism;
the water-soluble polymer is then set in motion by the horizontal screw located at the bottom of said storage and distribution container B;
the water-soluble polymer then passes through the opening in the bottom of storage and distribution container B and the opening in the roof of dissolution container A;
the water-soluble polymer is found in the supply mechanism and then passes through the metering mechanism;
the water-soluble polymer is then sent to the dissolving mechanism;
the water-soluble polymer then passes through a hydration and dissolution tank equipped with a stirring system; and
finally, the water-soluble polymer is fed into a volumetric metering pump which meters the water-soluble polymer solution to be mixed with the injection fluid.
