Title:
DEVICE AND METHOD FOR SEPARATING OFF WATER AND RECOVERING A CARBOXYLIC ACID FROM REACTOR DISCHARGE DURING AN AROMATIC COMPOUND OXIDATION REACTION USING ENERGY DONATING COUPLED DISTILLATION
Document Type and Number:
WIPO Patent Application WO/2013/039288
Kind Code:
A1
Abstract:
The present invention relates to a method for separating off reaction-product water from reactor discharge during the oxidation of an aromatic compound, and for recovering a carboxylic acid used as a solvent within the reactor, and, more specifically, relates to a method for separating off reaction-product water from reactor discharge during the oxidation of an aromatic compound, and for recovering a carboxylic acid used as a solvent within the reactor, wherein, during the oxidation of the aromatic compound, the discharge from the reactor is led into two or more dewatering towers having different operating pressures, such that the condenser of one of the dewatering towers acts as the reboiler of another dewatering tower, thereby markedly reducing energy use.
