Abstract
Near-critical carbon dioxide was used in
conjunction with cosolvents to efficiently
concentrate ethanol and acetic acid from water
solutions in a process developnent unit-scale
continuous liquid-liquid extractor. The use of
cosolvents has reduced the overall solvent
requirements resulting in smaller equipment
size and lower costs, and effective use of a
vapor recompression cycle in the process design
has significantly reduced energy consumption.
