  • Patent number: 11643603
    Abstract: A non-aqueous extraction (NAE) process for producing bitumen from oil sands ore can include a multistage bitumen extraction step where paraffinic solvent and deasphalted oil are added at a downstream stage of extraction at solvent-to-bitumen ratios below asphaltene precipitation onset threshold to remove bitumen from the solid mineral material, while the ore is added to a first stage to mix with the solvent-bitumen mixture and produce solvent diluted bitumen. The process includes recovering the solvent diluted bitumen and the solvent diluted tailings from the extraction step. The solvent diluted bitumen is subjected to deasphalting to produce solvent diluted deasphalted bitumen that is used as a source of the paraffinic solvent and deasphalted oil supplied to extraction. The tailings and asphaltene fraction from deasphalting can be subjected to washing and the washed material can then be subjected to sand solvent recovery.

  • Patent number: 11629297
    Abstract: Disclosed herein are methods, systems, and compositions for providing catalysts for tail gas clean up in sulfur recovery operations. Aspects of the disclosure involve obtaining catalyst that was used in a first process, which is not a tailgas treating process and then using the so-obtained catalyst in a tailgas treating process. For example, the catalyst may originally be a hydroprocessing catalyst. A beneficial aspect of the disclosed methods and systems is that the re-use of spent hydroprocessing catalyst reduces hazardous waste generation by operators from spent catalyst disposal. Ultimately, this helps reduce the environmental impact of the catalyst life cycle. The disclosed methods and systems also provide an economically attractive source of high-performance catalyst for tailgas treatment, which benefits the spent catalyst generator, the catalyst provider, and the catalyst consumer.
