Abstract
Systems and methods for improving crude acetone column energy efficiency and operation are provided. The method for improving crude acetone column energy efficiency and operation can include introducing a crude acetone including acetone and phenol to a fractionation column and introducing cumene, AMS, or a combination thereof to the fractionation column. The method can include fractionating the crude acetone within the fractionation column to produce an acetone containing overhead and a phenol containing bottoms. The method can also include condensing at least a portion of the acetone containing overhead indirectly with a cool heat transfer medium to provide a condensed crude acetone product and a heated heat transfer medium, wherein the heat transfer medium includes cumene.
