Problems with continuous distillation-mass balance–questions from reading

This post was last edited by *nren1 on 2020-1-15 at 17:32. A beginner wants to ask some experts a question: I previously studied applied chemistry, but now I have switched to chemical engineering. In textbooks on principles of chemical engineering, for the material balance in continuous distillation, it is generally expressed as F=D+H, with the units being kmol/h. Why are the material balance calculations in the book all done using kmol/h as the unit? I checked over the past couple of days but couldn’t find any relevant information; I hope someone experienced can help me out.
I had no prior experience with distillation, so I’m not sure if it’s a standard practice in this industry
When performing distillation calculations, both units of kmol/h and kg/h can be used directly. You can try solving a distillation problem on your own; if the units given are kmol/h, you can convert them to kg/h – the resulting value will be the same (with only minor differences due to rounding)
