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.
