Energy consumption in purge distillation columns

摘要: Distillation columns are often used to purge undesirable components from a reactor recycle system. A portion of the stream is fed column. There an optimum column feed rate, which minimizes energy consumption in distillation In this paper, two cases considered. first, component be purged heavier (less volatile) than main stream. The bottom product second system, overhead distillate since lighter (more recycle.
