Laboratory treatability testing of selected oil shale process wastewaters
Gas condensate wastewaters are generated by cooling of retort offgases produced by in situ facilities. These waters are characterized by high concentrations of ammonia and alkalinity, and contain moderate concentrations of dissolved organic materials. Metallic elements are present in low concentrations. Location of retorting facilities in arid areas of the western United States is expected to increase utilization of wastewater recycle/reuse options, with treatment requirements depending upon end use quality requirements. Laboratory-scale experiments were conducted with an actual modified in-situ gas condensate to assess performance of steam stripping, the activated sludge process and activated carbon adsorption for upgrading the quality of this wastewater. Steam stripping experiments were carried out with a laboratory-scale, packed tower which contacted preheated, raw gas condensate with low pressure steam in a countercurrent manner. A bench-scale, continuous-flow activated sludge system was operated to evaluate the capability of this treatment technology for removal of dissolved organics. Continuous-flow tests were conducted with steam-stripped gas condensate and effluent from the activated sludge system to assess the ability of carbon adsorption for removal of dissolved organics. A field test configuration for treatment of gas condensate wastewaters has been developed, and pilot-scale units of each treatment technology will be procured during 1981. This mobile pilot equipment will be tested at retorting facilities to demonstrate control technology performance under actual retort operating conditions.
