摘要：
The process of separating ethanol from aqueous solutions using supercritical carbon dioxide is in the development stage and was investigated experimentally using a bench scale test plant. It was operated under conditions based on previous data (Furuta et al. 1990). The results showed that more than 99 mol% of ethanol could be concentrated without any entrainer. A reflux ratio grater than 2 was required for good extraction efficiency. For recycling use, carbon dioxide was easily separated from ethanol using a high pressure distillation column.
