    摘要: The present invention consists of treating the surface of a viscous semi-solid oil or water-in-viscous oil emulsion with a chemical dispersant composition that has a viscosity which is sufficiently high that the dispersant will remain in contact with the oil for a time sufficient to disperse it in the water. Thus, in one embodiment of the present invention a chemical dispersant composition for dispersing viscous, almost semi-solid oils in water comprises a dispersing agent and an oil soluble polymer in a ratio whereby said composition has a viscous, sticky, gel-like consistency.

    摘要: Mixtures of C.sub.10 -C.sub.20 aliphatic carboxylic acids or the sorbitan monoesters thereof, sorbitan monoacrylates in combination with nonpolar solvent systems are effective oil collecting agents for containing oil slicks floating on a water surface. The invention, therefore, describes a method whereby oil slicks floating on a water surface may be contracted by applying to the perimeter of the oil slick an effective amount of an oil collection agent as described above, whereby the surface area of said oil slick is reduced. After the size of the oil slick is reduced by means of the oil collection agent, the oil may then be physically removed from the water. An advantage of treating oil slicks in this manner is that the method aids in the removal of the oil completely from the water. The oil collection agents encompassed by the present invention have the additional advantages of having low toxicities as well as pour points low enough to enable their use during operations where water and/or air temperatures are less than 45.degree.F.

    摘要: An agent and a method for dispersing spilled oil, particularly on a body of water. The compound is a viscous dispersant liquid comprising a mixture of surfactants and a viscosifying agent that may be stored, shipped, mixed, and delivered on site using standard equipment and methods. The compound is released as a cohesive, persistent, visible, gel-like or paste-like liquid that floats on water. At least one method includes delivering the viscous dispersant liquid onto an oil spill in a body of water utilizing a jet airplane flying at over about 100 feet and spraying the liquid in large, pea-sized droplets.

    摘要: A method for dispersing an oil spill on sea water, which method comprises applying to the oil spill surface an effective amount of: (i) a blend of one or more hydrophilic and one or more lipophilic surfactants so balanced that they will form microemulsions with the sea water and the oil to be dispersed; (ii) a solvent which is miscible with the oil to be dispersed and in which the blend of surfactants is substantially soluble; and (iii) from 0 to about 10 weight percent water, wherein the blend of surfactants is such that it lowers the interfacial tension between the oil to be dispersed and the sea water to less than about 250 mdynes/cm when the blend is used at a treat rate of less than about 1 to 100 by weight, based on the oil to be dispersed, wherein the solvent is a hydrocarbon solvent selected from the group consisting of No. 2 diesel fuel oil, kerosene and white oil.

    摘要: The present invention relates to a method for separating water and oil from a sludge which contains water, oil and solids which method comprises (1) contacting the sludge with an effective amount of 1 or more surfactants chosen and balanced to form certain types of microemulsions with equal volumes of decane and 3% aqueous NaCl, (2) mixing said surfactants and sludge with sufficient agitation to obtain a uniform mixture, (3) allowing said mixture to stand under gravitational settling or centrifugation to obtain the separation from the bottom sediment of an aqueous phase which may contain solubilized oil with or without an additional floating oil phase, (4) decanting separately the oil and aqueous phases and (5) further treating the aqueous phase with heat and/or NaCl to separate the solubilized oil or further treating the bottom sediment with selected surfactants to release adhering oil.
