This study investigated the use of near criticalsupercritical carbon dioxide NCSCCO2 extraction as a method for removing oily and greasy contaminants from bilge water on deployed U.S. Navy ships. This report gives a brief discussion of the sources and composition of bilgewater, followed by an introduction to NCSCCO2 extraction technology and its use for water treatment. The ARL investigation concentrated on the following areas 1 Characterization of effects of temperature, pressure and surfactant concentration on equilibrium partitioning of contaminants between the aqueous and NCSCCO2 phases. 2 Development of techniques to defeat the detrimental effects of surfactants. 3 Preliminary column sizing estimates based on the equilibrium partition data.
