    摘要: A process for the production of an oil-in-water emulsion for pipeline transmission. The process comprises producing a hydrocarbon crude, and mixing the produced hydrocarbon crude with an emulsifying composition(s) which contains water and is capable of assisting the formation of an oil-in-water emulsion when the temperature of the mixture of produced hydrocarbon crude and emulsifying composition(s) is from about 100.degree. F. to about 200.degree. F. The amount of the emulsifying composition(s) that is mixed with the produced hydrocarbon crude is sufficient to form an oil-in-water emulsion having water content of from about 15 percent to about 60 percent by weight water and a viscosity sufficiently low for pipeline transmission. The process additionally comprises shearing and mixing the mixture of produced hydrocarbon crude and emulsifying composition(s) when the mixture is at a temperature of from about 100.degree. F. to about 200.degree. F. to form an oil-in-water emulsion.

    摘要: A process suitable for operation at a mine site for recovering a hydrocarbon from a hydrocarbon bearing sand comprising the steps of mixing a chemical additive with a chemical composition and with a hydrocarbon bearing sand containing hydrocarbon and residual solids including clay, at a temperature to form a slurry. The chemical composition comprises an aqueous phase and a minor amount of a chemical agent selected from the group consisting of at least one ethoxylated alkylphenol compound, at least one ethoxylated dialkylphenol compound, MIBC, SC-177, Petronate HL, Calcium Lignosulfonate, NaOH and mixtures thereof. The slurry is conditioned and aerated to produce essentially sludge-free tailings and a mixture of hydrocarbon, aqueous phase and residual solids including clay. The process further comprises the step of separating in a short-residence time apparatus the mixture of the hydrocarbon, the aqueous phase and the residual solids including clay from the essentially sludge-free tailings.
