Definitions
- Polyacrylamides have been developed for more than 60 years especially for flocculation operations. However, since the oil shock of 1973, it has been recognized that polyacrylamides have a very high viscosifying power allowing their use in the Assisted Recovery of Petroleum alone or in conjunction with surfactants and alkalis. It has also been found that polyacrylamides have the power to reduce the friction of water or aqueous solution. This characteristic makes it possible to pump, by the addition of small amounts (30 to 500 ppm) of polymer, higher volumes of water into the same equipment or to reduce the power absorbed for pumping the same quantities.
- Toms' effect The reduction of friction was discovered by BAToms in 1946 ("Toms' effect") and its applications were developed in the field of the transport of water or aqueous suspensions (water-oil mixture), in fracturing operations , and various processes in contact with the water with high power absorbed (torpedoes, fight against the fire, cutting jet of water ).
- a floor surface incompatible with the movement of materials is
- PSU Polymer Slicing Unit
- the PSU described in patent WO 2008/107492 is an industrial material rotating at a low industrial speed (3000 to 4500 rpm) thus having a long life especially in oil operations or fracturing.
- Hardware reliability is a very important point. For example, stopping the introduction of polymers in a fracturing operation may lead to the clogging of the gas production well by settling of the sand used.
- the PSU basically includes:
- a grinding chamber of the dispersed polymer comprising a rotor associated with a stator
- a ring fed by a secondary water circuit for spraying water under pressure and declogging the stator blades.
- the stator is composed of individual tungsten carbide plates or blades assembled via spacers on a peripheral ring.
- US 6,000,840, US 5,156,344 and FR 2777804 A1 all disclose a cylindrical stator having vertical slots.
- the stator is surrounded by a ring comprising the same number of slots as the stator and whose size is identical to those of the stator. The position of this crown can be adjusted so that the slots of the stator can be fully open or fully closed.
- the size of the slots of the stainless steel stators described in these documents is not specified.
- the rotor comprises tungsten carbide inserts bolted or soldered to reduce wear during these operations.
- the binder (cobalt or nickel) does not have sufficient corrosion resistance, particularly in the petroleum industry where the brines pumped contain very large amounts of salts (up to 200,000 ppm) and hydrogen sulphide.
- the problem that the invention proposes to solve is therefore that of improving the construction of the PSU by allowing:
- the Applicant has found that these 4 objectives were fulfilled thanks to the implementation, for the manufacture of the rotor and the stator, of stainless steels, in particular austeno-ferritic steels called "superduplex" or hardened austenitic steels.
- surface vacuum nitriding, kolsterisation
- the subject of the invention is a device for dispersing a water-soluble polymer with a standard particle size of less than 1 mm, comprising:
- a grinding and evacuating chamber of the dispersed polymer comprising:
- a ring fed by a secondary water circuit, the ring communicating with the chamber so as to ensure the spraying of water under pressure on the stator.
- the device is characterized in that the blades of the rotor at least in part, and the stator are made of stainless steel selected from austenitic-ferritic or austenitic steels treated by vacuum nitriding or by carbon diffusion and in that the stator is present in the form of a cylinder in the wall of which its arranged vertical slots made on part of the height of said wall, the slots having a minimum width of 150 microns, preferably between 150 and 700 microns.
- the slots have a height of between 10 and 50 mm and are located equidistant from the upper and lower edges of the cylinder. In the case of high slots height, these will be cut into 2, 3 or 4 parts.
- the slots are spaced regularly from each other by a distance of between 10 and 50 mm.
- the inner walls of the slots are inclined to create sharp edges on each slot.
- the rotor and stator can be made of different materials.
- they are made of 304L or 316L austenitic stainless steel vacuum-nitrided but with lower performance and longevity than the austenitic-ferritic steels.
- they are made of austenitic ferritic steel containing at least 20% by weight of Cr and at least 5% by weight of Ni.
- the so-called “duplex” steels containing about 22% by weight of Cr and about 5% by weight of Ni are distinguished and the so-called “superduplex” steels containing between 24 and 26% by weight of Cr and 6 to 8% by weight of Ni.
- the austenitic-ferritic steels are keratinized, that is to say processed by carbon diffusion as explained later.
- the austeno-ferritic steel chosen has one of the following two compositions:
- Tungsten carbide has mechanical properties superior to those of superduplexes, but superduplex are sufficiently high compared to the hardness of the polyacrylamide grain to allow a long life of rotors and stators.
- the super-duplex or duplex can be treated to increase the surface hardness by kolsterising to a thickness of 20 to 30 microns without degrading the corrosion resistance and without changing the geometry of the parts and achieve Rm greater than 1000.
- the Kolstérisation ® treatment is a method of surface modification of the structure of stainless steels. It consists of a diffusion of a large quantity of carbon from the surface towards the core of the material, without any addition of external elements and without manufacture of chromium carbide. This treatment is performed in the gaseous phase and at low temperature and can treat any shape including slots such as PSU. This treatment is effective up to temperatures of 300 ° C and pH greater than 2. This process allows resistance to fatigue and corrosion resistance, removal of galling, very high hardness while maintaining non-magnetism .
- stator it has been chosen to use a crown or cylinder of the same internal diameter as the PSU on which slots are cut with a last-generation water-jet cutout capable of forming slots with a minimum width of 150 microns with a unit jet and any other width by a two-pass jet.
- This stator must have a high rigidity and its thickness is preferably at least 10 mm up to 20 mm so as not to lose the precision of the cut. It is also possible with high precision waterjet equipment to make conical cuts allowing better ejection of the ground polymer.
- the cutting is performed with a high-pressure water jet cutting machine containing an abrasive, at a pressure between 2000 and 5000 bar, preferably between 3000 and 4000 bar.
- a lower thickness is obviously possible but leads to deformations and breaks in the medium term, especially as a function of the inevitable erosion due to the grinding of the polymer.
- Cutting can also be done by laser but on small thicknesses, however the thermal effect creates permanent deformations and asperities on the slots thus cut forcing a filling of the piece after cutting.
- the number of slots of the stator is variable depending on the diameter of the latter. In practice, it is 50 to 300.
- the knives of the rotor are at least partly made of austenitic-ferritic stainless steel or austenitic vacuum-treated or keratinized.
- the rotor consists of a support on the surface of which the knives are formed by milling.
- the rotor is made in its entirety in one of the abovementioned materials.
- the rotor consists of a machined support made of one of the previously described materials on which are reported platelets made of tungsten carbide or stainless steel cured by heat treatment. In both cases, maintenance can be done to recover rotor-stator distances by machining the inside of the stator to a larger diameter.
- the rotor it is possible to:
- the rotor is equipped with 2 to 20 knives, advantageously between 4 and 12. Nevertheless, depending on the diameter of the rotor, the number of knives may vary. For example, it is 9 for a rotor diameter of 200 mm.
- the knives are optionally more or less inclined relative to the radius of the rotor.
- this inclination is between 1 and 15 °, preferably between 2 and 10 °.
- the distance separating the rotor blades from the stator blades is between 50 and 300 microns, preferably between 100 and 200 microns, in practice of the order of 100 microns.
- the reduction in the width of the slots decreases the flow of powder and water of each device that can be restored in part by increasing the speed of the rotor to the industrial limit of 4500 rpm.
- the configuration of the stator makes it possible to grind the polymer more finely than the device described in document WO 2008/107492 in which the space between each individualized blade could not be, in practice, less than 500 micrometers without very significant reduction in the longevity of the device.
- the invention also relates to the use of the dissolution device of the invention in an installation for the implementation of a hydraulic fracturing process of oil or gas wells, assisted recovery. Petroleum, flocculation, preparation of cosmetic solutions or household products. It also makes it possible to significantly reduce the number of workpieces and the complexity of the assembly.
