This invention relates to a process for making a paper or cardboard sheet from a fibrous suspension, comprising the following steps: a) injecting a P3 polymer into a suspension of cellulosic fibers, b) forming a paper or cardboard sheet, c) drying the paper or cardboard sheet, the P3 polymer being prepared, prior to step a), from a water-soluble P1 polymer of at least one nonionic monomer selected from acrylamide, methacrylamide, N,N-dimethylacrylamide and acrylonitrile, the P1 polymer being subjected to an Re1 reaction to give a P2 polymer, which is then subjected to an Re2 reaction to give the P3 polymer, which is injected into the fibrous suspension within 24 hours of the start of the Re1 reaction, - the Re1 reaction comprises preparing a P2 polymer comprising isocyanate functions by reaction for 10 seconds to 60 minutes between (i) an alkali hydroxide and/or an alkaline earth hydroxide, (ii) an alkali hypohalite and/or an alkaline earth hypohalite and (iii) the P1 polymer, - the Re2 reaction comprises preparing a P3 polymer by reaction between (iv) a micro-cellulose compound and (v) the P2 polymer comprising isocyanate functions.
The present application relates to an injection fluid F for hydraulic fracturing comprising at least one synthetic water-soluble polymer P with a weight-average molecular weight greater than or equal to 1 million daltons, said fluid being prepared according to a method comprising the following successive steps: a) preparing, by radical polymerization, an inverse emulsion E comprising between 15% and 40% by weight of polymer P, between 20% and 60% by weight of water and at least one hydrocarbon-based solvent, the percentages being expressed by weight relative to the weight of the emulsion E, b) distilling the inverse emulsion E to obtain a dispersion D comprising between 40% and 60% by weight of particles of polymer P, less than 10% by weight of water and at least one hydrocarbon-based solvent, the percentages being expressed by weight relative to the weight of the dispersion D, c) diluting the dispersion D with 1% to 15% by weight of an aqueous solution S comprising between 20% and 60% by weight of salts, the percentages being expressed by weight relative to the weight of the dispersion D.
The invention relates to a method for the removal of supernatant from media on a filter, where flocculant and/or coagulants are added to a media to enhance the drainage rate of supernatant, leaving the media at least partially dewatered, during which the surface topography of the media is measured and the amount of flocculant and/or coagulant to be added is a function of the topography of the media above the filter within a region of interest, or regions of interest.
Method of in-situ crosslinking a polymer treated mineral slurry residues from a mineral processing operation, in which said mineral slurry residues comprises an aqueous liquid with dispersed particulate mineral solids, characterised by: (a) combining with said mineral slurry residues a water-soluble ionic polymer such that the dispersed particulate mineral solids of the mineral slurry residues are positively or negatively charged such that said mineral slurry residues are treated, and then (b) combining with said treated mineral slurry residues a ionic crosslinking agent such that a in-situ crosslinking occurs in the structure of the treated mineral slurry residues, and wherein the ionicity of the water-soluble polymer and the ionicity of the crosslinking agent are opposite.
