METHODS AND APPARATUSES FOR PHENOL FRACTIONATION IN A SINGLE DIVIDING WALL COLUMN

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. 本公开涉及使用单个分隔壁蒸馏塔进行酚分馏的方法和装置。本公开更具体涉及将粗丙酮塔和异丙基苯-AMS塔合并到单个分隔壁蒸馏塔中的用于酚分馏的方法和装置。蒸汽或水注入、化学处理反应器和内部液相分离器、侧取位置的适当配置能够实现丙酮和酚的高收率。
