    摘要： A water stream containing hardness minerals is subjected to a water treatment process using an alkali agent to precipitate the hardness minerals and to produce a softened water stream is used to create an integrated water treatment and flue gas desulfurization process. Thereafter, the softened, alkaline water stream is utilized in a scrubber to scrub a flue gas containing sulfur dioxide to produce a sulfur-lean flue gas. The invention may be applied to a steam-based bitumen recovery operation where bitumen, sour produced gas or other sulfur containing fuels are burned for producing steam for bitumen recovery. More specifically, the associated produced water from the bitumen recovery process may be softened for re-use and for utilization as a scrubbing agent for high-sulfur containing flue gas arising from the steam generators. The process provides an economically favorable process while minimizing waste disposal requirements.

    摘要： The invention relates to a process for splitting bitumen into two fractions and rendering a heavier bottom fraction as a useable emulsion fuel. The process is particularly effective in creating an alternate fuel to natural gas in a steam-based bitumen recovery process wherein bitumen is recovered from an underground reservoir.

    摘要： A process is described for pre-treating an aqueous bituminous feed for downstream bitumen extraction. The process involves removing water from an aqueous bituminous feed having a water content of 60% or more by weight. After water is removed, an effluent comprising 40% water or less is formed, and is ready for downstream extraction. In the downstream extraction process, a dual solvent extraction process may be employed, incorporating agglomeration of fines to simplify subsequent solid-liquid separation. The process permits recovery of hydrocarbon that has conventionally remained in waste streams from oil sands processing, and thus has conventionally been lost. In one embodiment, removing water comprises subjecting the aqueous bituminous feed to a primary water separation system to reduce the water content of the feed, followed by subsequent water removal, thereby producing an effluent having a water content of 40% or less, which can then go on to further processing.
