SYNERGISTIC USE OF PHENOL PURIFICATION TRAIN IN PHENOL PRODUCTION UNIT FOR PROCESSING PHENOLIC WATER FROM BISPHENOL-A PRODUCTION UNIT

摘要

Systems and methods for recovering phenol have been disclosed. At least a portion of a wastewater stream from a bisphenol-A production process and a phenol stream that is produced by separating a crude phenol stream from a cumene based phenol production process are concurrently processed in a hydrocarbon removal unit to produce (i) a purified phenol stream comprising 95 to 99.9 wt.% phenol and (ii) an aqueous stream comprising water and byproducts of the phenol production process.
