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

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. 在个实施方式中，由双酚A生产设施回收苯酚的方法包括使苯酚和丙酮反应以产生双酚A流；将双酚A流分离成产物双酚A流和纯化流；将纯化流分离成初级顶部出口流和初级底部出口流；向初级底部出口流添加酸催化剂以形成裂化器入口流；将裂化器入口流分离成裂化器顶部出口流和裂化器底部出口流；将裂化器顶部出口流和裂化器底部出口流分离成次级顶部出口流和次级底部出口流；形成双酚A设备苯
