    Abstract: A hydrophobic coating has been made for use on interior pipe surfaces, exterior boat surfaces, and in many other applications, to reduce drag in fluid flow, thus providing an energy savings. The coating utilizes a blend of organic and/or inorganic polymers with hydrophobic nanoparticles of fumed silica and/or titania in a solvent. The coating solves the problem of poor resistance to UV light and/or abrasion found in previous coatings of similar nature. The coating of the present invention can be made to be translucent and nearly transparent whereas previous coatings of comparable hydrophobicity have all been white or opaque. The coating can be applied in a single application by an easy spraying method and the super hydrophobic property can be achieved by drying the film at room temperature for 5 to 10 minutes. A preferred coating has good resistance to UV light and some resistance to abrasion.

  • Publication number: 20120035297
    Abstract: The present embodiment can teach a method of feeding to a materials processor a mixture containing an agglomerated drag reducer. The mixture is then homogenized to produce a remediated drag reducer. The maximum particle size diameter of the agglomerated drag reducing polymer is at least 5% larger than the maximum particle diameter of the remediated drag reducer.

  • Publication number: 20120004344
    Abstract: A method of producing treated liquid hydrocarbons. The method begins by pressurizing a latex in a pressure vessel. This is followed by flowing the latex from the pressure vessel into a pipeline containing liquid hydrocarbons to produce treated liquid hydrocarbons. In this embodiment the latex comprises a drag reducing polymer.

  • Publication number: 20120004343
    Abstract: A method begins by obtaining a slipstream of a liquid. The slipstream of liquid is then mixed upstream of an injection pump with a latex comprising a drag reducing polymer to produce a drag reducing mixture. The drag reducing mixture is then injected into a liquid hydrocarbon to produce a treated liquid hydrocarbon.

  • Publication number: 20110319520
    Abstract: Fine particulate polymer drag reducing agents (DRAs) in bi-modal or multi-modal particle size distributions may be produced simply and efficiently without cryogenic temperatures. The grinding or pulverizing of polymer, e.g. non-porous poly(alpha-olefin) suitable for reducing drag in hydrocarbons may be achieved by the use of at least one liquid grinding aid and at least two grinding processors in series. The blades of the stators of the grinders are of different configuration so that granulated polymer fed to the first processor having relatively larger gaps between blades is ground to an intermediate size which is fed to the second processor having relatively smaller gaps between blades which grinds the polymer to a second, smaller size. A non-limiting example of a suitable liquid grinding aid includes a blend of propylene glycol, water and hexanol. Particulate DRA may be produced at a size of 300 microns or less in only two passes.

  • Patent number: 8022118
    Abstract: A system for reducing pressure drop associated with the turbulent flow of asphaltenic crude oil through a conduit. The crude oil has a high asphaltene content and/or a low API gravity. Such reduction in pressure drop is achieved by treating the asphaltenic crude oil with a high molecular weight drag reducing polymer that can have a solubility parameter within about 20 percent of the solubility parameter of the heavy crude oil. The drag reducing polymer can also comprise the residues of monomers having at least one heteroatom.

  • Patent number: 7939584
    Abstract: Drag reduction of hydrocarbon fluids flowing through pipelines of various lengths is improved by polyolefin drag reducer dispersions or dispersions using bi- or multi-modal particle size distributions. Drag reducers having larger particle sizes dissolve more slowly than drag reducers having smaller particle sizes. By using at least bi-modal particle size distributions drag reduction can be distributed more uniformly over the length of the pipeline where smaller sized particles dissolve sooner or earlier in the pipeline and larger sized particles dissolve later or further along the pipeline.

  • Patent number: 7888407
    Abstract: A drag reducing composition comprising at least one non-polyalphaolefin polymer having an average particle size in the range of from about 5 to about 800 micrometers. The non-polyalphaolefin polymer can initially be formed via emulsion polymerization. The initial polymer particles can then be at least partially consolidated and then reduced in size and suspended in a carrier fluid. The resulting drag reducing composition can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.
