Abstract:
In an embodiment, a method of recovering acetone comprises separating a bisphenol A stream into a bisphenol A product stream and an extraction stream comprising unreacted acetone; recovering the unreacted acetone in a recovery section of the bisphenol A production facility and forming a bisphenol A plant acetone recovery stream comprising methanol and a recovered acetone; introducing the bisphenol A plant acetone recovery stream to a phenol purification plant; and purifying the bisphenol A plant acetone recovery stream in the phenol purification plant to form an acetone product stream. The acetone product stream can comprise a reduced amount of methanol as compared to the bisphenol A plant acetone recovery stream.
