Abstract: A process for removing contaminants, namely water and particulate solids, from hydrocarbon diluent-diluted bitumen froth (“dilfroth”) is provided to produce hydrocarbon diluent-diluted bitumen (“dilbit”), comprising subjecting the dilfroth to gravity settling in a primary settler to produce an overflow stream of primary raw dilbit, comprising bitumen containing water and some fine solids, and an underflow stream of primary tails, comprising solids, water and residual bitumen; removing the overflow stream of primary raw dilbit and subjecting it to gravity settling in a clarifier vessel for sufficient time to produce an overflow first stream of cleaned dilbit and an underflow stream of clarifier sludge; diluting the primary tails with hydrocarbon diluent and subjecting the diluted primary tails to gravity settling in a secondary settler to produce an overflow second stream of cleaned dilbit and an underflow stream of secondary tails; and removing the clarifier sludge and diluting the clarifier sludge with a hyd

Abstract: A process for extracting bitumen from oil sand, comprising: mixing oil sand with process water to produce an oil sand slurry containing bitumen, sand, water and entrained air; conditioning the oil sand slurry; optionally flooding the conditioned oil sand slurry with flood water to dilute the slurry, if required; introducing the slurry into a primary separation vessel wherein separate layers of primary bitumen froth, middlings and sand tailings are formed; removing a portion of the primary bitumen froth from the primary separation vessel and recycling the portion of primary bitumen froth to that step of the process upstream of the primary separation vessel to join and mix with the feed stream moving to the primary separation vessel; and thereafter retaining said feed stream in said primary separation vessel to produce primary bitumen froth.

Abstract: 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.

Abstract: A process for treating water containing dissolved organics, for example, oil sands process-affected water, using petroleum coke is provided, comprising: removing petroleum coke from a coking operation; forming a petroleum coke/water slurry by adding the water to be treated to the petroleum coke; and mixing the slurry for a sufficient time in a carbon adsorption reactor to allow the petroleum coke to adsorb a substantial portion of the dissolved organics from the water.
