METHOD OF RECOVERING PHENOL FROM A BPA PRODUCTION PLANT AND THE PLANT FOR RECOVERING THE SAME

摘要

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.
