  • Publication number: 20140319063
    Abstract: A process for obtaining random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates is by polymerization in an aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator. The copolymers can be used as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage in an oil reservoir, obstruction of water injection and crude oil production pipelines, and in production rigs due to mineral scale precipitation caused by high levels of salinity of the injection water and formation water. Random copolymers are tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and can be added to the reservoir and to injection or production pipelines, treated water, sea water and water that is used as means of transportation.

  • Publication number: 20140263078
    Abstract: Methods for dispersing foulants are disclosed herein. Various effective dispersant compositions are also disclosed. The dispersant composition can include a silt dispersant and a hydrocarbon dispersant. Generally, the silt dispersant can be a homopolymer or a copolymer of one or more monomers, and the monomers can be one or more of acrylic acid, methacrylic acid, ?-halo acrylic acid, maleic acid, itaconic acid, vinyl acetic acid, allyl acetic acid, fumaric acid, ?-carboxylic acrylate, and their salts. The silt dispersant can also be a terpolymer of acrylic acid, acrylamide, and sulfonated acrylamide. The hydrocarbon dispersant can be a non-ionic surfactant or a nonylphenol or a nonylphenol ethoxylate, such as a high EO 9 Nonyl phenol resin. Also disclosed are methods for preventing or reducing fouling in equipment that contacts water used during a hydrocarbon production process.

  • Publication number: 20140217033
    Abstract: A surface active compound is supplied into contact with an oilfield production fluid that comprises a mixture of water and oil including water soluble organics. The surface active compound comprises at least one alkoxylate chain and at least one end group attached to each of the at least one alkoxylate chain. The surface active compound is supplied into the oilfield production fluid at a dosage rate that is effective to self-associate at interfaces between the water and oil and inhibit the water soluble organics in the oil from entering the water when the oilfield production fluid is depressurized.

  • Patent number: 8734635
    Abstract: Elimination and/or mitigation of fouling in a vapor transport systems, such as vent lines and scrubber feed lines may be accomplished using an antifouling additive. The method for employing the antifouling additive includes introducing into the vapor transport system an additive including a polar solvent and corrosion inhibitor wherein: the vapor transport system is substantially water free; the vapor transport system is used to transport acidic materials; the additive is a liquid at vapor transport system operating conditions; and the additive is stable at the vapor transport system operating conditions.

  • Patent number: 8734653
    Abstract: A mercury remediation method and apparatus for reducing mercury levels in water to a nanogram per liter level that uses four treatment steps: (1) chelation; (2) oxidation; (3) reduction; and (4) air stripping, vapor/liquid separation. There is a fifth step in the process, which does not involve the wastewater. It is to scrub the stripper air of the volatile mercury in an off-gas adsorption unit or to condense volatile mercury in a cryogenic mercury trap.

  • Publication number: 20140124451
    Abstract: The invention provides methods and compositions for inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more GPS-surfactant based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.
