Abstract: In an embodiment, a method of recovering phenol comprises heating a preheater inlet stream in a preheater to form a splitter inlet stream; separating the splitter inlet stream into a splitter top outlet stream and a splitter bottom outlet stream in a splitter column; separating the splitter bottom outlet stream into a crude top outlet stream and a crude bottom outlet stream in a crude phenol column; hydro-extracting the crude top outlet stream in a hydro-extractor column to form an extractor primary outlet stream; recovering a product phenol outlet stream from the extractor primary outlet stream in a finishing column; combining a bisphenol A plant phenol recovery stream from a bisphenol A reaction from a bisphenol A phenol purification system with the preheater inlet stream, the splitter inlet stream, the splitter bottom outlet stream, the crude top outlet stream, or a combination comprising at least one of the foregoing.

Abstract: In an embodiment, a method of recovering phenol from a bisphenol A production facility comprises reacting phenol and acetone to produce a bisphenol A stream; separating the bisphenol A stream into a product bisphenol A stream and a purge stream; separating the purge stream into a primary top outlet stream and a primary bottom outlet stream; adding an acid catalyst to the primary bottom outlet stream to form a cracker inlet stream; separating the cracker inlet stream into a cracker top outlet stream and a cracker bottom outlet stream; separating the cracker top outlet stream and the cracker bottom outlet stream into a secondary top outlet stream and a secondary bottom outlet stream; forming a bisphenol A plant phenol recovery stream; combining the bisphenol A plant phenol recovery stream with a stream of a phenol purification plant.
