Abstract

See full text

A process for treating water containing dissolved organic compounds, including naphthenic acids, for example, oil sands process water, using petroleum coke is provided, comprising: removing petroleum coke from a coking operation; forming a petroleum coke/water slurry by adding the water containing dissolved organic compounds to the petroleum coke; adding a pH-lowering agent to the petroleum coke/water slurry either during slurry formation or after slurry formation to form a treated petroleum coke/water slurry; and allowing the treated petroleum coke/water slurry to mix for a sufficient time in a carbon adsorption reactor to allow the petroleum coke to adsorb a substantial portion of the dissolved organic compounds from the water.
