    • Techniques for recovering degraded bitumen from oil sands tailings can include retrieving water and degraded bitumen from the tailings and conditioning the water and degraded bitumen to produce an oil-in-water emulsion. The conditioning can include providing a pH of at least 8; dispersing the bitumen in the water; adding an emulsion stabilizer; and adding an alkaline regeneration compound. The oil-in-water emulsion can then be subjected to regenerative transport in order to regenerate the degraded bitumen in the oil-in-water emulsion and produce a regenerated emulsion. The oil-in-water emulsion has sufficient stability to remain emulsified during the regenerative transport. The regenerated emulsion can then be separated into an aqueous component including a portion of the emulsion stabilizer and a bitumen froth component including regenerated bitumen. The bitumen froth component can then be supplied to a bitumen extraction operation to produce extracted bitumen.
    • 从油砂尾矿回收降解的沥青的技术可以包括从尾矿中回收水和降解的沥青,并调节水和降解的沥青以产生水包油乳液。 调理可以包括提供至少8的pH; 将沥青分散在水中; 加入乳液稳定剂; 并加入碱性再生化合物。 然后可以将水包油乳液进行再生输送,以便再生水包油乳液中的降解沥青,并产生再生乳液。 水包油乳剂具有足够的稳定性,在再生输送过程中保持乳化。 然后将再生乳液分离成包含一部分乳液稳定剂的水性组分和包含再生沥青的沥青泡沫组分。 然后将沥青泡沫组分提供给沥青提取操作以产生提取的沥青。
