Abstract (en)
[origin: EP2660420A1] The equipment has a silo (4) for storing powder polymer (15). A polymer slicing unit (9) includes a cone for wetting the powder polymer, and is connected to a primary water inlet circuit. A ring communicates with a dispersed polymer grinding and drainage chamber to ensure spraying of pressurized water over an outer side of a fixed stator for enabling release of ground and swollen polymer at a stator surface. Two positive-displacement pumps enable injection and metering of the solution obtained in a mixer used for supplying a high-pressure fracturing pump. An independent claim is also included for a method for hydraulic fracturing of gas or oil wells by injection of a fluid.
