Abstract: Systems and methods for recovering phenol have been disclosed. The methods of recovering phenol includes concurrently processing, in a phenol recovery unit, a crude phenol stream from a phenol production unit, and a bisphenol-A purge stream from a bisphenol-A production unit to produce a first product stream comprising 60 to 95 wt. % phenol. The phenol recovery unit comprises a crude phenol distillation column and a bisphenol-A-phenol distillation column. The processing includes distilling a bottom stream from the crude phenol distillation column in the bisphenol-A-phenol distillation column.
