Definitions
- the subject of the present invention is a concentrated multiphase suspension of high molecular weight water-soluble synthetic polymer particles used as rheology modifiers, flocculants, suspending agents or friction reducers in multiple applications such as the treatment of industrial and municipal water, the recovery assisted oil in a deposit, hydraulic fracturing, treatment of mining effluents, drilling operations in civil engineering and oil and gas operations, manufacture of sheets of paper and cardboard, agriculture, textiles, detergents, cosmetics.
- High molecular weight synthetic water-soluble polymers are commonly used for many applications due in particular to their flocculant, thickening or friction-reducing properties. Indeed, these polymers have use in the oil and gas industry, hydraulic fracturing, papermaking processes, sludge dewatering, water treatment, construction, mining, cosmetics, agriculture, textile and detergent industry.
- the flocculant nature of these high molecular weight water-soluble synthetic polymers is used in the field of water treatment / sludge dewatering. Indeed, after an optional coagulation step where the colloidal particles present (similar to spheres of size less than 1 micrometer) are destabilized, flocculation represents the step where the particles are gathered into high-weight aggregates to generate rapid sedimentation. .
- the water-soluble polymers thus used for water treatment are mainly in the form of powder or water-in-oil inverse emulsion. Depending on the water to be treated, the physical properties of the flocculant are modulated.
- the ionic character nonionic, anionic, cationic, amphoteric, zwitterionic
- the molecular weight or even the structure (linear or structured, even crosslinked) of the water-soluble polymer can be adapted.
- the rheology modifying character of these polymers can be exploited in the field of enhanced oil recovery (RAP or EOR, acronym for
- high molecular weight water-soluble polymers can act as a friction reducer in aqueous solutions.
- the stretching of the polymer chains in solution makes it possible to delay the turbulent regime established during the transport of the fluid at high speed. The consequence is a reduction in the energy required to transport the aqueous solution.
- these polymers can also act as a rheology modifier and/or as a suspending agent for proppants, for example sand.
- these polymers can also generate viscosity and induce suspensivating properties in aqueous formulations used in the cosmetics, detergent and industrial hygiene, textile and agricultural industries.
- Synthetic water-soluble polymers of high molecular weight can be obtained according to all the polymerization techniques well known to those skilled in the art. It can in particular be a question of polymerization in solution; gel polymerization; precipitation polymerization; emulsion polymerization (direct or reverse); suspension polymerization; reactive extrusion polymerization; water-in-water polymerization; or micellar polymerization.
- the polymerization is generally free radical polymerization, preferably by inverse emulsion polymerization or gel polymerization.
- free radical polymerization we include free radical polymerization initiated by means of UV, azo, redox or thermal initiators, as well as controlled radical polymerization (CRP) techniques or matrix polymerization techniques.
- CRP controlled radical polymerization
- the (co)polymer can be in liquid or solid form (powder or microbeads), in the form of an aqueous dispersion, an inverse emulsion or a suspension (suspension of particles in an oil).
- the preferred physical forms of these water-soluble polymers are powder or microbeads because they provide a high percentage by weight of active material.
- the physical powder form of these polymers can be obtained by drying, thermo-drying, spray drying and drum drying. However, their re-dissolution requires appropriate equipment, for example a grinding unit in a wet environment for powders such as a PSU (“Polymer Slicing Unit”).
- Inverse emulsions are interesting but they require rigorous optimization of their formulation so that their inversion in an aqueous medium is the fastest and their stability (during storage and transport) is guaranteed (in particular during freeze/thaw cycles).
- water-soluble polymers of high molecular weights can be obtained in the form of aqueous dispersion according to a process called polymerization in aqueous dispersion.
- the polymer is polymerized directly in an aqueous solution comprising at least one compound chosen from an inorganic salt, an organic salt, a dispersing organic polymer and mixtures thereof.
- Another technique consists in formulating an aqueous dispersion of high molecular weight water-soluble polymers by dispersing solid polymer particles in an aqueous solution comprising at least one compound chosen from an inorganic salt, an organic salt, a dispersing organic polymer, a viscosifying rheology modifier, and mixtures thereof.
- Another technique consists in formulating a particulate suspension of high molecular weight water-soluble polymers by dispersing solid polymer particles in an oily or solvent phase.
- the aqueous or oily dispersion/suspension of water-soluble polymers of high molecular weight is particularly unstable, viscous and has poor resistance to freeze/thaw cycles.
- These aqueous or oily or solvent-based dispersions/suspensions of polymers present storage and stability problems, in particular at low temperature (freezing), even if they are prepared, not by dispersion polymerization, but by dispersion of polymer particles in a brine containing, among other things, balancing agents such as dispersant polymers.
- Oily suspensions are also little used because oils are not recommended, or even prohibited, for certain applications for ecological reasons and also because these suspensions additionally present pumpability problems.
- This polyphasic suspension is prepared by dispersing and concentrating solid particles of high molecular weight water-soluble polymers using an innovative process in a mixture comprising a brine and a lipophilic apolar solvent to which other additives are added.
- This multiphase suspension of polymer particles is particularly stable, whether over time or at low temperature (low settling, little creaming, no increase in viscosity). It is also resistant to freeze/thaw cycles. It has the advantage of having a high limit threshold of polymer particles that can be incorporated and dispersed (this threshold is defined by the limit above which destabilization of the formulation is observed, which results in gelling). Finally, the viscosity of this multiphase suspension remains low despite a mass concentration of polymer greater than 10%. In addition, the carbon footprint of this multiphase solution is reduced because its preparation does not require heating and therefore no use of heat transfer fluid, but also because its oil content is low, and its concentrated polymer form involves less production costs. transportation, not to mention the lack of dissolving equipment for its use.

- Another aspect of the invention relates to the use of this multiphase suspension SP of particles of synthetic water-soluble polymer P for the treatment of industrial water, the treatment of municipal water, enhanced oil recovery in a deposit, hydraulic fracturing, treatment of mining effluents, drilling operations in civil engineering, drilling operations in the oil industry, drilling operations in the gas industry, the manufacture of sheets of paper or cardboard, agriculture, textiles, detergents, or cosmetics.

- the intrinsic viscosity value is read on Y-axis or using the least squares method. Then the weight average molecular weight can be determined by the famous Mark-Houwink equation: [r

- Example 1 Preparation and comparison of the stability of a multiphase suspension of water-soluble polymer particles and of an oily suspension of water-soluble polymer. a) Preparation of a multiphase suspension and an oily suspension of water-soluble polymer particles.
- the synthetic water-soluble polymer PI is a copolymer of acrylamide and sodium acrylate, containing 30 mol% sodium acrylate.
- the copolymer before preparation of the suspensions is in the form of a powder whose particle size is between 5 ⁇ m and 300 ⁇ m and the content of active material (polymer) is 90% by weight.
- Polymer P1 has a weight average molecular weight of 15 million daltons.
- the multiphase suspension SP1 containing 50% by weight of polymer PI is prepared according to the method of the invention: an oily suspension is prepared by adding to mineral oil with stirring 60% by weight of polymer particles PI and 1.5% by weight of emulsifying agent, then a solution of calcium chloride, containing attapulgite, is added to the oily suspension to obtain a multiphase suspension.
- the last step in the preparation is to add the inverting agent (ethoxylated alcohol (8 ethoxylations)).
- the oily suspension SH1 containing 50% by weight of polymer PI is prepared by suspending particles of PI in mineral oil to which the other ingredients have been added: [Table 1]
- the dynamic stability of the SP1 and SH1 suspensions was characterized by measuring the sedimentation rate.
- the equipment used is the LUMISizer® marketed by the company LUM GMBH.
- the LUMISizer® is an analytical centrifuge, which allows the stability of polymer suspensions to be determined in an accelerated manner. Thanks to a very high performance optical system, the LUMISizer® makes it possible to analyze the sedimentation and/or creaming velocities of solid polymer particles. This speed is expressed in mm/month. The higher this value, the less stable the dispersion (see Table 2).
- the SP1 and SHI suspensions underwent 3 cycles of temperature rise to 30°C and fall to -30°C.
- the visual observations of the different suspensions are described in Table 3.
- polyphase dispersion of polymer SP1 is more stable than the oily suspension SH1. It also demonstrates that the multiphase suspension SP1 retains its homogeneity, its fluidity, and its pumpability, even after several freeze/thaw cycles, unlike the oily suspension SH1 which becomes viscous after only 2 freeze/thaw cycles and then gels after 6 freeze/thaw cycles.
- Example 2 Preparation and comparison of the stability of a multiphase suspension of water-soluble polymer particles and of an aqueous dispersion of water-soluble polymer. a) Preparation of a multiphase suspension and an aqueous dispersion of water-soluble polymer particles.
- the synthetic water-soluble polymer P2 is a terpolymer of acrylamide, sodium acrylate (20 mol%) and sodium acrylamido tert-butyl sulfonate (5 mol%).
- the copolymer before preparation of the suspensions/dispersions is in the form of a powder whose particle size is between 5 ⁇ m and 300 ⁇ m and the content of active material (polymer) is 90% by weight.
- Polymer PI has a weight average molecular weight of 24 million daltons.
- the multiphase suspension SP2 containing 15% by weight of polymer P2 is prepared according to the method of the invention (same protocol as for SP1)
- the aqueous suspension SA1 containing 15% by weight of polymer PI is prepared by dispersing particles of P2 in the brine to which the other ingredients have been added.
- the dynamic stability of the SP2 suspension and of the SA2 dispersion was characterized by measuring the sedimentation rate (as for example 1).
- the polyphasic suspension SP1 of example 1 is used here (prepared according to the same protocol).
- the inverse emulsion EI1 containing 50% by weight of polymer PI is prepared by controlled radical polymerization in inverse emulsion according to a method known to those skilled in the art. b) Stability assessment
