Molecular Distillation With Reflux

What is the reflux ratio in distillation ... Aug 11, 2019 The reflux ratio, which is the ratio of reflux rate to distillate rate can influence separation efficiency. In total reflux mode, 100% of the streams are recycled back into the column. However, practical distillations are operated in partial reflux mode to achieve economic separation.
