Near Critical/Supercritical Carbon Dioxide Extraction for Treating Contaminated Bilgewater

Abstract

This study investigated the use of near critical/supercritical carbon dioxide (NC/SCCO2) 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 NC/SCCO2 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 NC/SCCO2 phases. (2) Development of techniques to defeat the detrimental effects of surfactants. (3) Preliminary column sizing estimates based on the equilibrium partition data.
