摘要： A method of treating tailings comprising a solids fraction and a hydrocarbon fraction is disclosed. A primary flow is supplied to a jet pump, the primary flow comprising water and less than 20% solids by mass. A secondary flow is supplied to a mixing chamber of the jet pump, the secondary flow comprising a slurry of water and tailings, the slurry comprising more solids by mass than the primary flow. The jet pump is operated using the primary flow such that the tailings are agitated to effect at least a partial phase separation of the hydrocarbon fraction from the tailings. The methods disclosed herein may also be applied to treat tailings ponds.

摘要： Heavy crude oils are transported by pipeline from deposit location to a remote upgrading location by emulsifying the crude oil using deaerated sodium hydroxide solution, conveying the oil-in-water emulsion through the pipeline, and recovery of the oil from the oil-in-water emulsion by inverting the emulsion and dewatering the resulting water-in-oil emulsion. The emulsion inversion may be effected using slaked lime, resulting in recovery of a substantial proportion of the sodium hydroxide used in the initial emulsification. The sodium hydroxide solution may be recycled by a separate pipeline for reuse or treated for discharge.
摘要翻译：通过使用脱气的氢氧化钠溶液乳化原油，通过管道输送水包油乳液并从水包油中回收油，重质原油通过管道从存放位置运输到远程升级位置通过颠倒乳液并使得到的油包水乳液脱水来乳化。可以使用熟石灰进行乳液反转，导致在初始乳化中使用的大部分氢氧化钠的回收。氢氧化钠溶液可以通过单独的管道再循环以供重新使用或被处理用于排放。

摘要： The sulphur emissive capability, on combustion, of coke which is formed during upgrading of sulphur-containing heavy crude oils, including oil sands bitumen, and residua, is decreased by the addition of calcium carbonate, calcium hydroxide or calcium oxide, in particulate form, to the heavy crude oil prior to coking, and uniformly dispersing the same therein. The presence of the calcium compound leads to an increased yield of liquid distillates from the coking process under the coking conditions. For calcium carbonate, the Ca:S ratio is about 1:5 to 1:1 and the coking temperature is about 400.degree. to 500.degree. C. For calcium hydroxide and calcium oxide, the Ca:S ratio is about 1:3 to 1:1 and the coking temperature is about 450.degree. to about 500.degree. C.
摘要翻译：通过添加颗粒形式的碳酸钙，氢氧化钙或氧化钙，降低了含硫重质原油（包括油砂沥青）和残渣在升级期间形成的焦炭的燃烧后的硫发射能力，在焦化之前是重质原油，并将其均匀分散在其中。钙化合物的存在导致焦化条件下焦化过程中液体馏出物的产量增加。对于碳酸钙，Ca：S比为约1:5至1:1，焦化温度为约400至500℃。对于氢氧化钙和氧化钙，Ca:S比为约1:3至1 ：1，焦化温度约450℃〜约500℃

摘要： The sulphur emissive capability, on combustion, of coke which is formed during upgrading of sulphur-containing heavy crude oils, including oil sands bitumen, and residua, is decreased by the addition of calcium carbonate, preferably in the form of limestone, to the heavy crude oil prior to coking. The presence of the limestone leads to an increased yield of liquid distillates from the coking process under preferred coking conditions. Ash remaining after combustion of the coke may be leached to recover nickel and vanadium values therefrom.

摘要： Heavy oils, including oil sands, are recovered from mined or in-situ formation by a novel procedure which involves an initial emulsification of the oil with aqueous alkali, usually sodium hydroxide solution, at a pH above about 11. After separation of any residual solid phase, such as sand, the resulting oil-in-water emulsion is inverted by the use of slaked lime to form a water-in-oil emulsion and thereby regenerating part of the sodium hydroxide solution. The water-in-oil emulsion is dewatered to recover the oil phase while the aqueous phase is recycled to the initial emulsification, after removal of clay particles when oil sands are treated.
