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
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.
A process for the extraction and recovery of a hydrocarbon from water wet tar sands comprising: (a) introducing a water wet tar sand and water into a conditioning zone to form a tar sand slurry having a temperature ranging from about 100°F. to about 130°F.; (b) agitating the formed tar sand slurry o
A process for the extraction and recovery of a hydrocarbon from water wet tar sands comprising: (a) introducing a water wet tar sand and water into a conditioning zone to form a tar sand slurry having a temperature ranging from about 100°F. to about 130°F.; (b) agitating the formed tar sand slurry of step (a) to form an agitated tar sand slurry; (c) aerating the formed agitated tar sand slurry to form an aerated tar sand slurry comprising a first mixture including first fines, first water, first hydrocarbon and first solids; (d) separating in a primary separating zone the first solids from the first hydrocarbon and first water and first fines of the aerated tar sand slurry to produce a second mixture comprising a second hydrocarbon, a second fines, and a second water; (e) separating the second hydrocarbon from the second mixture of step (d) to produce a third mixture comprising third fines, third water, and third solids; (f) introducing the first solids into a secondary separating zone to produce a fourth mixture comprising fourth fines, fourth water, fourth hydrocarbon, and fourth solids; (g) separating in the secondary separating zone the fourth solids from the fourth fines, fourth water and fourth hydrocarbon; (h) passing the fourth fines, the fourth water and fourth hydrocarbon into the conditioning zone of step (a); (i) introducing the fourth solids into a tertiary separating zone to produce a fifth mixture comprising fifth fines, fifth water, fifth hydrocarbons and fifth solids; (j) separating in the tertiary separating zone the fifth solids from the fifth fines, fifth water and fifth hydrocarbon; and (k) admixing the fifth fines, the fifth water and fifth hydrocarbon with the fifth solids prior to said introducing step (f).
