Title:
METHODS AND APPARATUSES FOR PHENOL FRACTIONATION IN A SINGLE DIVIDING WALL COLUMN
Document Type and Number:
WIPO Patent Application WO/2017/172617
Kind Code:
A3
Abstract:
This present disclosure relates to processes and apparatuses for use of a single dividing wall distillation column for phenol fractionation. More specifically, the present disclosure relates to processes and apparatuses for phenol fractionation by combining crude acetone column and cumene-AMS column into a single dividing wall distillation column. The proper allocation of steam or water injection, chemical treatment reactor and internal liquid phase separator, the positioning of the side draw enables high yield of acetone and phenol.
