Treatment of retort water for co-disposal with spent shale
Review of several treatment processes which are potentially useful for removing organic matter from retort water indicates high treatment costs. The costs are particularly high for complete organic removal. If selective partial removal is allowed (e.g, removal only species of organics that are highly mobile in groundwater or only compounds that are noxious), treatment costs may be reduced. Further research is needed to characterize organic compounds in the retort water so that specific compound removal may be possible and criteria for minimum degree of treatment for co-disposal can be established. Relative to industrial wastewater treatment costs, costs may be high, but the cost per barrel of oil may be acceptable. If a treatment cost between $10 to 15/1000 gal is assumed, this implies a cost/barrel of oil for wastewater treatment to be $0.42 to 0.63. If the profit margin for shale oil is slim, this wastewater treatment cost may be excessive.
