摘要： An HIPR (high internal phase ratio) emulsion of oil in water is prepared by directly mixing 70 to 98% by volume of a viscous oil having a viscosity in the range 200 to 250,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant or an alkali, percentages being expressed as percentages by volume of the total mixture. Mixing is effected under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising highly distorted oil droplets having mean droplet diameters in the range 2 to 50 micron separated by thin interfacial films. The emulsions are much less viscous than the oils from which they are prepared and may, optionally after dilution, be pumped through a pipeline. Viscous crude oils may be transported by this method.

摘要： Heavy crude oil is recovered from tar sands by treatment with an aqueous solution containing a surfactant, e.g., an alkyl aryl sulphonate and a hydrophlic alkylene oxide polymer, e.g., polyethylene oxide.
Adding the alkylene oxide polymer enables the surfactant to be used in lower concentration and/or recovery to be increased.摘要翻译： 通过用含有表面活性剂（例如烷基芳基磺酸盐和亲水性环氧烷聚合物，例如聚环氧乙烷）的水溶液处理，从焦油砂中回收重质原油。 加入烯化氧聚合物使得能够以更低浓度使用表面活性剂和/或提高回收率。

摘要： Heavy crude oil is recovered from tar sand by treating the tar sand with a low concentration emulsion of a solvent in water containing 0.5 to 15% by volume of the solvent. Suitable solvents include hydrocarbons and halogenated hydrocarbons.
Solvent-in-water emulsions are efficient in extracting bitumen with the major advantage of greatly reduced solvent: tar sand ratios.摘要翻译： 通过用含有0.5至15体积％溶剂的溶剂的低浓度乳液处理焦油砂，从焦油砂中回收重质原油。 合适的溶剂包括烃和卤代烃。 溶剂水乳液在提取沥青方面是有效的，其主要优点是大大降低了溶剂：沥青砂比例。

摘要： @ An HIPR emulsion of bitumen in water is prepared by a method which comprises directly mixing 70 to 98% by volume of bitumen having a viscosity in the range 200 to 500,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant, percentages being expressed as percentages by volume of the total mixture. Mixing is effected under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising highly distorted bitumen droplets having mean droplet diameters in the range 2 to 50 micron separated by thin films of water.
The emulsions can be cut back to provide stable emulsions of lower bitumen content which are useful in road- making and the formation of protective coatings.摘要翻译： 通过一种方法制备沥青在水中的HIPR乳液，该方法包括在混合温度下将70至98体积％的具有200至500,000mPa.s的粘度的沥青与30至2体积％的水溶液 乳化表面活性剂的溶液，百分比表示为总混合物的体积百分比。 在低剪切条件下在10至1000个倒数秒的范围内进行混合，使得形成包含高度变形的沥青液滴的乳液，其具有由薄膜水分离的2至50微米的平均液滴直径。 乳液可以被切断以提供可用于道路制造和形成保护性涂层的较低沥青含量的稳定乳液。
