    Abstract: A product is used in creating an active capping layer across submerged (and optionally exposed) surfaces of contaminated sediment, with the product including multiple, dry particles composed of variable types and amounts of inert material, reactive material and binding material. To create optimal characteristics for controlled and relatively rapid settling through a water column, the dry particles can selectively comprise different sizes, size gradations and shapes (as a function of procedures for manufacturing and processing) as well as different density, or specific gravity (as a function of optionally including relatively very dense minerals). The dry particles are manufactured by implementing the sequential steps of material mixing into a flowable paste, paste drying, crushing and optionally sieving.

  • Patent number: 7449429
    Abstract: An initial chemical composition comprising selected surfactants, dispersants, and degreasers that liquefy, disperse, demulsify, degrease, inhibit corrosion and scale formation, and lower the pour point of a petroleum, coal, Fischer-Tropsch synthesized, or naturally occurring paraffin-based wax and asphaltene. Such a product is capable of converting crystalline wax (paraffin) in, for example, slop oil into an amorphous form of wax at room temperature, allowing the wax to be dissolved in, for example, crude oil without the need for heating, and maintaining it in solution at room temperature, substantially reducing, indeed in some applications, preventing, for example, wax build-up in pipelines, processing and transportation equipment, etc., and the recovery of the hydrocarbons in the slop oil. In a second aspect of the invention, the pre-blend addition of a hydrotrope-demulsifier, a chelating agent and a wax plasticizer can result in a BS&W of zero for the recovered hydrocarbon blend.
