    摘要: Methods for reducing calcium deposition along surfaces in contact with the water phase of a resolved water/oil emulsion are disclosed. High calcium crude oil and the like are contacted with a sequestrant to form a sequestered calcium containing complex that partitions to the water phase in the resolved emulsion. A specifically formulated polymeric deposit control agent is added to the water phase to inhibit calcium deposit formation therein and along surfaces in contact with the water phase.

    摘要: The invention deals with a method and composition(s) for use in inhibiting corrosion of metallic parts in contact with aqueous systems. It has been discovered that protective oxide films can be formed on the metallic surface if such is allowed to contact an aqueous system containing a sufficient amount for the purpose of a polymer composed primarily of acrylic moieties and hydroxylated lower alkyl acrylate moieties and a water-soluble orthophosphate. Optionally but desirably, polyphosphates, organo-phosphonates, and copper corrosion inhibitors may be included.

    摘要: A method of inhibiting the formation and deposition of scale forming moieties in aqueous systems by adding water-soluble or water-dispersible polymers is disclosed. The method comprises adding to an aqueous system a polymer having repeat units characterized by the Formula I: Wherein E is the repeat unit remaining after polymerization of an ethylenically unsaturated compound; preferably, a carboxylic acid, sulfonic acid, phosphonic acid, or amide form thereof or mixtures thereof. R1 is H or lower (C1-C4)alkyl. G is —CH2— or —CHCH3—; R2 is &Parenopenst;CH2—CH2—O&Parenclosest;n or &Parenopenst;CH2—CHCH3—O&Parenclosest;n where n ranges from about 1 to 100, preferably about 1 to 20. X is an anionic radical selected from the group consisting of SO3, PO3, or COO; Z is H or hydrogens or any water soluble cationic moiety which counterbalances the valence of the anionic radical X, including but not limited to Na, K, Ca, or NH4. F, when present, is a repeat unit having the structure of Formula II: wherein X and Z are the same as in Formula I. R4 is H or lower (C1-C4)alkyl. R5 is hydroxy substituted alkyl or alkylene having from about 1 to 6 of carbon atoms.
