Description:
Near critical carbon dioxide was used to extract hazardous organic chemicals from three aqueous waste streams in a pilot plant scale continuous liquid-liquid extraction system. Extractions were performed on waste streams representative of actual streams from steel, pesticide, and acrylonitrile manufacturing plants. An extractor plate efficiency was determined based on the Kremser-Souder-Brown equation using the results of the acrylonitrile waste runs. The efficiency was used to design a commercial scale extractor. A conceptual design for a commercial scale process is also presented.
