Title:
気泡塔反応器型分解装置、及びその使用方法
Document Type and Number:
Japanese Patent JP6882182
Kind Code:
B2
Abstract:
A method for digestion of a crude terephthalic slurry obtained from oxidation of para-xylene in a bubble column reactor oxidation process is provided. The method is conducted in one or more bubble column reactors having one or more segregrated zones defined by horizontal baffles and particle flow through the digestion system is controlled to maximize conversion of partial oxidation intermediates to terephthalic acid while minimizing formation of other contaminant products. Temperature, oxygen flow and content as well as other process and equipment variables are controlled throughout the process to support formation of terephthalic acid. Also provided are bubble column digestion systems structured to conduct the digestion method.
