    摘要: An oil-in-water emulsion of crude oil, water and hydrophilic surfactant is resolved by first heating said emulsion until it separates into a surfactant laden water layer and an oil-rich emulsion layer, removing the water layer from the oil-rich emulsion layer, treating the emulsion layer by the addition of from 20 to 40 volume percent of water containing a demulsifier and recovering the crude oil which separates from the water upon standing.

    摘要: A method for the recovery of fugitive dust by encapsulation of fugitive calcined coke dust into agglomerate balls having substantial compressive strength which involves the steps of water-wetting calcined coke dust with an aqueous solution of a polyethoxylated alkyl phenol wetting agent to provide moist coke dust and thereafter admixing the moist dust with an asphalt emulsion whereby nonfriable agglomerate balls of asphalt encapsulated calcined coke dust can be recovered.

    摘要: A method of enhancing the geotechnical properties of soil materials so as to control soil erosion including fugitive dust by treating the soil with a mixture of polyacrylic acids or polyacrylates, a dibasic acid or acid salt and a wetting agent in water utilizes an aqueous solution of a polyacrylate emulsion, (said active polymer having a Mw of 1-5 million), sodium citrate and a surfactant (nonylphenol plus 10 moles ethylene oxide). The mixture is applied directly to the soil to be stabilized in either diluted or undiluted form whereby surface erosion in both quiescent areas and road beds can be controlled.

    摘要: A method for treating particulate solids such as coal to reduce the cohesive strength of such solids when frozen which consists of spraying said solids with a hydrocarbon liquid solution of a balanced blend of surfactants which blend will form a single phase microemulsion at 20.degree. C. when added to water at the salinity of the water on said solids at a water to hydrocarbon ratio in the range between 99:1 and 85:15, said blend represented by the monoethanol amine salt of dodecyl o-xylene sulfonic acid and a dinonylphenol reacted with 9 moles of ethylene oxide, onto the wetted surface of said solids to form a single phase microemulsion which is optimally designed to undergo a lipophilic shift upon contacting the surface of said particles whereby an in-situ water-in-oil coarse emulsion is formed on the surfaces of said particles.
