  • Patent number: 7407599
    Abstract: The present invention relates to a carboxylic acid based antifreeze coolant formulation for heavy duty applications such as for diesel engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic carboxylic organic acid, azoles, low levels of molybdates, a nitrite salt and/or nitrate salt and/or siloxane stabilized silicate, and combinations thereof, polyvinylpyrrolidone, provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges.

  • Patent number: 5209946
    Abstract: A method and apparatus for treating tubulars (e.g. pipelines, flowlines, tubing, casing, etc.) for corrosion, drag reduction, or the like wherein a mass comprised of a gelatin mixture and magnetic particles is passed through the tubular to deposit a protective layer onto the inner wall of the tubular. The micro particles of magnetized material are entrained within the mass of gelatin and are deposited along with the gelatin to aid in adhering the protective layer on the tubular wall.

  • Patent number: 4610218
    Abstract: An apparatus for intimately contacting particulate solids with a heavy liquid, said apparatus comprising:(a) a contacting vessel;(b) a particulate solids inlet in communication with an upper end of the contacting vessel;(c) a generally conical deflector positioned in the contacting vessel beneath the particulate solids inlet;(d) an inlet control to control the flow of the particulate solids into the contacting vessel and prevent the discharge of gaseous materials from the contacting vessel;(e) a particulate solids outlet in communication with a lower end of the contacting vessel;(f) an outlet control to control the flow of particulate solids from the contacting vessel so that a bed of particulate solids is maintained in a lower portion of the contacting vessel; and,(g) spray nozzles positioned in the contacting vessel to spray heavy liquid onto the particulate solids as they fall downwardly to the bed of particulate solids.
