  • Polymers as additives for the separation of oil and water phases in emulsions and dispersions
    Patent number: 8956529
    Abstract: Oil-water dispersions and emulsions derived from petroleum industry operations are demulsified and clarified using anionic polymers. Formation of such oil-water dispersion and emulsions is inhibited and mitigated using the anionic polymers. The anionic polymers comprise: A) 2-80% by weight of at least one C3-C8 ?,?-ethylenically unsaturated carboxylic acid monomer; B) 15-80% by weight of at least one nonionic, copolymerizable ?,?-ethylenically unsaturated monomer; C) 1-50% by weight of one or more of the following monomers: C1) at least one nonionic vinyl surfactant ester; or C2) at least one nonionic, copolymerizable ?,?-ethylenically unsaturated monomer having longer polymer chains than monomer B), or C3) at least one nonionic urethane monomer; and, optionally, D) 0-5% by weight of at least one crosslinker.
    Type: Grant

  • Method for separating oil from water in petroleum production
    Patent number: 5643460
    Abstract: A method for separating emulsified oil from water in petroleum production is disclosed. Low molecular weight polymers of dimethylaminoethyl acrylate methyl chloride and benzyl chloride quaternary salt have good activity as reverse emulsion breakers for freeing oil tied up as a oil-in-water emulsion. The polymer reverse emulsion breakers are preferably prepared and used as aqueous solutions to obviate the need for inversion techniques and the use of hydrocarbon compatibilizers and surfactants as required for a latex polymer.
