摘要： A method for recovering NH3 present in a sour water stream containing odiferous compounds such as pyridines, indoles, ketones and mercaptans produced during an upgrading process for upgrading bitumen from oil sands into synthetic crude comprising treating the sour water stream in a sour water treatment unit to produce a NH3-rich stream and a H2S-rich stream; and hydrotreating the NH3-rich stream in a hydrotreater in the presence of hydrogen to remove the odiferous compounds such as pyridines, indoles, ketones and mercaptans and produce a treated NH3-rich stream.

摘要： A process for extracting bitumen from oil sand using a combination of heavy solvent and light solvent is provided comprising digesting mined oil sand with a high-flash point heavy solvent (HS) to produce a dense oil sand slurry; mixing the dense slurry with a light solvent (LS) to give a heavy solvent to light solvent (HS/LS) mass ratio of about 70/30 to about 50/50 and subjecting the thinned oil sand slurry to a first stage solid-liquid separation to produce a first liquids stream containing bitumen and a first solids stream. The first solids stream is washed with a mixed solvent having a HS/LS mass ratio of about 75/25 to about 55/45 and the solids and mixed solvent are subjected to a second stage solid-liquid separation to produce a second liquids stream and a second solids stream. This process may be integrated with the existing water-based extraction through ore segregation, energy integration and MFT reduction/sequestration to further enhance its economical and environmental benefits.

摘要： A process for extracting bitumen from oil sand using a combination of heavy solvent and light solvent is provided comprising contacting mined oil sand with a non-flammable heavy solvent (HS) to produce a dense oil sand slurry; mixing the dense slurry with a light solvent (LS) to give a heavy solvent to light solvent (HS/LS) mass ratio of about 70/30 to 50/50 and subjecting the diluted oil sand slurry to a first stage solid-liquid separation to produce a first liquids stream containing bitumen and a first solids stream; mixing the solids stream with a mixed solvent having a HS/LS mass ratio of about 75/25 to 55/45 and subjecting the diluted solids stream to a second stage solid-liquid separation to produce a second liquids stream and a second solids stream; rinsing the solids stream with a countercurrent flow of LS to recover the HS and produce spent solids; and drying the spent solids to LS concentration of less than 160 g/tonne solids.
