Near Critical/Supercritical Carbon Dioxide Extraction for Treating Contaminated Bilgewater

Abstract

This study investigated the use of near critical carbon dioxide (NCCO2) extraction as a method for removing oily and greasy contaminants from bilge water on deployed US Navy ships. The investigation involved the following tasks: A. Qualitative and quantitative evaluation of the operation of a packed bed counterflow extraction column with near critical carbon dioxide as the extraction phase. B. Measurement of desorption rates to determine appropriate retention times for recovery of CO2 from treated bilgewater. C. Evaluation of separator designs for removal of contaminants from carbon dioxide gas prior to recycling.
