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.
Claims15
An installation for storing, metering, and dissolution of water-soluble polymer articles comprising;
- a container A of a generally parallelepipedic shape comprising side walls forming long and short sides, a bottom and a roof, wherein said container A comprises at least one supply of the polymer, at least one metering mechanism of the polymer and at least one mechanism for dissolving the metered polymer, characterized in that the installation further comprises at least one container B of a generally parallelepiped shape positioned on container A, comprising side walls forming long and short sides, a roof, and a bottom, and wherein the bottom of container B and the roof of container A each have an opening facing each other, allowing the passage of polymer from container B into the at least one supply of the polymer from container A, wherein the bottom of container B comprises a mechanism for setting the polymer in motion in the form of a horizontal screw, wherein the installation further comprises a connection mechanism capable of working with the at least one supply of the polymer.
The installation according to characterized in that the mechanism for dissolving the metered polymer is a water-soluble polymer grinding dispersion device and comprises:
- a water-soluble particle polymer wetting cone connected to a primary water supply circuit,
- at lower end of the cone, a grinding and drainage chamber for the dispersed water-soluble polymer comprising:
- a rotor driven by a motor and equipped with knives,
- a fixed stator made of a cylinder with fine slots,
- on all or part of the periphery of the chamber, a ring fed by a secondary water circuit, the ring communicating with the chamber in such a way as to ensure the spraying of water under pressure on an outside of the stator, thus allowing the release of crushed and swollen water-soluble polymer on a surface of said stator.
