A device for dispersing a water-soluble polymer includes a primary water inlet circuit that feeds an overflow, at the bottom end of the cone, an assembly including a chamber for grinding and draining the dispersed polymer, having a rotor driven by a motor provided with knives, a stator, over all or part of the periphery of the chamber, a ring fed by a secondary water circuit, the ring communicating with the chamber by way of slots for spraying pressurized water onto the stator The slots of the stator and/or the knives of the rotor are tilted at an angle of between 20&#xb0; and 80&#xb0; relative to the horizontal plane of the stator and the lateral face of the blade next to the stator is curved in such a way as to make the distance separating the two components substantially constant.

Device for dispersing a water-soluble polymer

A pressure regulating device for the injection of an aqueous polymer solution into an oil well, the device consisting of a series of straight tubes each with a pressure gauge, each tube being separated by a valve, where the valves are gate valves and/or needle valves. A method to reduce the injection pressure of an aqueous polymer solution according to the pressure of the well using the device.
