Patent ID: 8800659

Claim:
A compact and transportable installation, which is quick to start up and is independent, which allows for dissolution of at high concentration, in very short periods of time, substantial quantities of polyacrylamide powder and which is designed to be used in fracturing operations on gas or oil fields, said installation successively including: a polymer storage area; a vertical polymer transfer hopper; a supply overflow pipe; a polymer dosing system fed by said pipe; a polymer slicing unit (PSU) type polymer dispersion device, the polymer dispersion device comprising: a polymer wetting cone connected to a primary water inlet circuit at a lower end of the cone, a dispersed polymer slicing and discharge chamber including a rotor driven by a motor and equipped with blades and a fixed stator made up of evenly spaced plates, and wherein over all or part of a periphery of the chamber a ring is supplied by a secondary water circuit, the ring communicating with the chamber so as to ensure spray of pressurized water over the plates of the stator thereby allowing for release of sliced and swollen polymer at a surface of the said plates; a tank for storage and degassing of polymer in solution; and a volumetric pump to inject and dose the solution of polymer obtained at a suction of a high pressure pump enabling the fracturing operations.
