    Abstract: Oil remediation compositions and methods for preparing such compositions are disclosed. The oil remediation compositions comprise particles of a first wax ester, such as a synthetic beeswax, and an anti-caking agent. The anti-caking agent may be a natural cellulosic material, such as particulate hay. In methods for preparing these compositions, the hydrophilic-lipophilic balance (HLB) of the composition may be adjusted by adding a second wax ester or fatty acid ester with a different HLB to reach a desired HLB for the composition that is based on defined environmental conditions, such as the temperature and salinity of the water in which oil has been spilled, the nature of the oil spilled, and the degree of evaporation of organic compounds.

  • Patent number: 8708600
    Abstract: In one embodiment, dispersants are injected directly into a plume of oil in a subsea environment. The dispersant is supplied from a vessel, through a tubular string and flows through a routing manifold into a flexible hose. The hose then transports the dispersant to a distribution manifold, which is disposed on the sea floor, and permits injection of dispersants at multiple locations at the same time around the leaking oil. Injection of dispersants from the distribution manifold may be through injection wands, or the dispersant may be transferred to a containment or collection device located above the plume of oil, wherein nozzles are disposed around the circumference of such containment or collection device. If the dispersants are injected into the leaking oil through injection wands, such wands may be held and/or manipulated by an ROV.

  • Patent number: 8101069
    Abstract: An External Filtering and Absorbing Device for Use in a Local Containment Area contains filter material with a mesh size not less than 50 microns for removing contaminants from ballast or bilge water from a ship or effluent from a storm drain. Examples of contaminants removed are aquatic nonindigenous species such as Fish, Zebra and Quagga Mussels, Asiatic Clam, Aquatic Weeds, Green Crabs, or other suspended particle contaminants. Filtering is accomplished above the ambient water allowing easy visual verification and visual gratification of the efficacy of the filter unlike closed on-board systems. Water and oil permeate the filter and flow into a local containment area where oil is absorbed by absorbent pads held in pockets. The filter is easily removed and can be sent to authorities to demonstrate compliance with environmental standards. Water sampling containers or instruments used with the assembly allow for further compliance monitoring.

  • Patent number: 5518797
    Abstract: A device to capture, contain and collect hydrocarbon fuels such as gasoline and diesel before they can be spilled or leaked from the ventilation valve or fuel intake port of the fuel tank of a vessel and on to the surface of the water during fueling operations at marine fueling facilities. The device is formed as a low-profile box with a floor section and upright wall sections having stratified layers of a textile material and a solidifying polymer enclosed within a outer envelope of textile material. A seamed area at the center of the device with slits in the textile material allows the device to circumscribe the annular conduit of a device passing through the seamed area.

  • Patent number: 5500267
    Abstract: A multi-layered, slip-resistant, absorbent, and disposable mat is provided for absorbing oil and other liquids while retaining a slip-resistant surface upon which to walk after the oil and other liquids have been absorbed. A first layer of the mat is a fluid impermeable sheet with a slip-resistant surface, such as biodegradable plastic, foil, or rubber material, with the slip-resistant surface facing down toward a floor surface. A second layer is a glue material applied onto the face up surface of the fluid impermeable sheet. A third layer is an absorbent material applied to the glue material. The absorbent material may be cotton fiber, polymer material, polyethylene sponge, cellulose fiber, or other suitable material or a combination thereof, and preferably shaped into spherical or cylindrical beads. A fourth layer is a non-absorbent, fluid-permeable and slip-resistant material placed over the absorbent material. The fourth layer may be a screen or mesh, preferably comprised of nylon or nylon-covered metal.

  • Patent number: 5498337
    Abstract: A process for biodegradation of crude oil wastes and for recovery of contaminated land including the steps of extracting sludges containing the wastes, collecting the sludges into a container, mixing an alkaline salt with the sludges so as to react the salt with the sludges under a generally constant degree of humidity, adding black earth to the mixed alkaline sludges so as to neutralize the alkaline sludges and to degrade the oil wastes through chemical reactions, adding a material to the neutralized sludges so as to enrich the sludges, and forming a humus of the neutralized sludges by the organic degradation of the neutralized sludges through fermentation or putrefaction. The material added to the neutralized sludges so as to enrich the sludges can be selected from the group including sawdust, rice husks, sugar cane bagasse, and animal excrement.

  • Patent number: 5494580
    Abstract: Method of decontamination of a hydrocarbon-polluted environment by the use of bacterial compositions. The method is a process of biological decomposition of the hydrocarbons using, as decontaminating active ingredients, bacterial compositions composed of one or more strains from among the following microorganisms: Azotobacter vinelandii 21, Pseudomonas sp.9, Pseudomonas sp.19, Pseudomonas sp.31 and Acinetobacter calcoaceticus 23. In the method, prior analysis of the chemical composition of the pollutants is essential in order to select, in accordance with this composition, the mixture of strains of the most active microorganisms from among the five mentioned above, taking into account the natural conditions of the polluted environment. The bacterial composition also contains inorganic salts supplying N and P, and additives needed for bacterial growth.

  • Patent number: 5458773
    Abstract: A pillow for placement in enclosed areas utilized to collect and contain spilled or leaked hydrocarbons such as boat bilges and sumps absorbs pollutants that come in contact. The absorbed material is solidified within the pillow into a rubber-like mass. The consolidated mass will float indefinitely and is easily retrieved and handled for disposal. The pillow will not leech solidified hydrocarbons when exposed to pressure limits used to determine landfill suitability.

  • Patent number: 5429741
    Abstract: Methods are described for treating sludge, e.g. biological and/or chemical sludge, with processed cellulose material combined with another material, e.g. a surface active agent, a detergent, a surfactant, a polymer and/or an organic polymer.Cellulose flakes and methods for making them are disclosed; in one aspect the flakes are useful as animal litter or bedding; in one aspect such used flakes are re-pelletized for use as litter, food or fertilizer. Methods for absorbing, removing, and for cleaning up a first liquid floating on or in a second liquid are disclosed, the method employing absorbent pellets which, in preferred embodiments, have a particular size, density, and configuration. A pellet and a method for making the pellet are disclosed for cleaning up a first liquid floating on or in a second liquid; and a method for making pellets for absorbing a combustible material to produce fuel pellets. A method for producing fuel pellets is disclosed.

  • Patent number: 5423340
    Abstract: A system for removing oil from oil/water or oil/sand or oil/water/sand mixtures. An oil/water mixture is taken from an oil spill on the surface of the water or from other sources such as producing oil wells and is transported to a surge tank where it is agitated and then passed on to a separator which separates the oil from the water. The system also covers separating oil from sand or earth when the spill is on land.
