Is there a minimum reflux ratio for the batch distillation? If so, how can we determine it experimentally? Please help me with this. I'm not sure since batch operates like one stage but the slope of the rectifying section is the same? Is it the same way as finding Rmin for Continuous distillation? Thanks!
