  • Patent number: 11452950
    Abstract: A demulsifying additive comprising a branched aliphatic compound may be introduced to a stream containing mixtures of or emulsions of oil and water in an effective amount to separate water from the oil in the stream, such as separating oil from emulsified oil-in-water and/or separating water from emulsified water-in-oil in a production fluid. The branched aliphatic compound may be grafted with a polyether via a crosslinking reaction. Alternatively, branched aliphatic compounds may be crosslinked together.

  • Patent number: 11390696
    Abstract: A procedure for improved temperature control in controlled radical polymerization processes is disclosed. The procedure is directed at controlling the concentration of the persistent radical in ATRP and NMP polymerizations procedures and the concentration of radicals in a RAFT polymerization process by feeding a reducing agent or radical precursor continuously or intermittently to the reaction medium through one of more ports.

  • Publication number: 20220195098
    Abstract: A process of manufacturing a composition comprises a particulate drag reducing agent is disclosed. The process comprising: continuously forming a temporary container; introducing an unsaturated monomer component and a radical polymerization component into the temporary container; sealing the temporary container to form a sealed temporary container; allowing the unsaturated monomer component to polymerize in the sealed temporary container to form the drag reducing agent via a radical polymerization reaction, the drag reducing agent having a molecular weight of about 1 million gram/mol to about 50 million gram/mol; and grinding the drag reducing agent to form a composition comprising a particulate drag reducing agent, the particulate drag reducing agent having a particle size of about 1 to about 1,500 microns.

  • Patent number: 11167222
    Abstract: A single-phase microemulsion additive may be introduced to a stream containing mixtures of or emulsions of oil and water in an effective amount to separate oil from the water in the stream and/or separating water from the oil in the stream. The single-phase microemulsion additive is formed by combining at least one demulsifier, at least one water clarifier, at least one surfactant, and optionally at least one solvent.

  • Patent number: 11168182
    Abstract: A polymer composition comprising star macromolecules is provided. Each star macromolecule has a core and five or more arms, wherein the number of arms within a star macromolecule varies across the composition of star molecules. The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest.

  • Publication number: 20210246377
    Abstract: A copolymer useful as a water clarifier for a water phase of a production fluid is selected from those with a first monomer and a second monomer, and in one non-limiting embodiment having the general formula: wherein y is 10 to 50,000; z is 1 to 10,000 and n is 1 to 250. The copolymer may optionally include a third monomer. In an optional embodiment of the process, the fluid has a hydrocarbon phase, and the process further involves simultaneously drying the hydrocarbon phase of the fluid along with clarifying the water phase.
