Is the reboiler heat duty of a distillation column approximately equal to the condensor heat duty? To a first approximation. I'll assume constant molar overflow,  no heat loss, no sidestream draws, no intercooling or pumparounds etc. All the usual simplifying assumptions. This isn't an accurate calculation (yet)

If not, is there a relation between condensor and reboiler duties? I'll assume I know the Feed, Distillate and Bottoms drawoffs and the reflux ratio.
