Abstract: A method of separating impurities from impure PO, the method comprising distilling impure PO in a distillation zone to provide distillate PO of enhanced purity, wherein heat is provided to the distillation zone by a bottoms reboiler and by an intermediate reboiler, the intermediate reboiler providing heat at a lower temperature than the bottoms reboiler. A suitable distillation system is also disclosed.
