摘要:
Disclosed is a method for treating oil sands tailings. The tailings are conditioned with an aluminate and treated with a silicate-containing stream from a hydrocarbon operation or from a geothermal source to produce chemically-induced micro-agglomerates (CIMA) and water.

摘要:
Disclosed is a method of processing bitumen streams using membrane filtration. In one aspect, membrane filtration replaces paraffinic froth treatment, with one or more filtration steps replacing gravity settling. In another aspect, the bitumen stream is subjected to paraffmic solvent treatment at much higher flow rates, with an “almost cleaned” product being subsequently filtered by the membrane system. In this case, some contaminants are removed by conventional gravity settling equipment, while additional contaminants are removed by membrane filtration. In another aspect, membrane filtration is applied to a bitumen product effluent stream following naphthenic froth treatment. In another aspect, membrane filtration is applied to a bitumen product effluent stream from a solvent-based extraction process. In yet another aspect, membrane filtration is applied to a bitumen product effluent stream from a solvent extraction with solids agglomeration process. In still another aspect, membrane filtration is applied to bitumen produced by SAGD.
摘要:
Generally, the present disclosure provides a process for treating de-oiled oilfield produced water or de-oiled process affected water from hydrocarbon production. In particular, such water is treated with a regenerable polymeric ion exchange resin to remove water soluble ionic surfactants. The treating can involve ion-exchanging ionic polymeric membrane foulants with non-fouling soluble ionic species that can be removed by polymeric membrane.
摘要:
An integrated treatment process and apparatus is provided for removing selected contaminants from both liquid and gaseous waste streams. A multistage separation and bio-oxidation substrate is provided in a column through which the contaminants are passed. The substrate components provide absorption, adsorption, ion exchange, solubility, and bio-degradation qualities to the column to effectively separate and destroy a wide range of contaminants in industrial waste streams.

A method of detoxifying a component of contaminated soil containing a halogenated organic compound including contacting the contaminated soil with atomic hydrogen in an amount effective to react with halogen contained in the compound and substituting the hydrogen for the halogen.
