Abstract:
Disclosed are an oxidation reactor for manufacturing an aromatic carboxylic acid and a method of manufacturing the aromatic carboxylic acid using the oxidation reactor. The oxidation reactor includes a reaction chamber, a stirring shaft disposed along a geometric vertical axis of the reaction chamber, and at least two stirrers, each including stirring blades, each stirring blade having either a curved portion or a bent portion formed on an end of the stirring blade to enable fluid to flow in the reaction chamber while preventing the fluid from remaining in the reaction chamber, and each stirring blade being extended radially along a direction perpendicular to the vertical axis to be rotated.
Abstract:
Disclosed is an oxidation reactor for manufacturing terephthalic acid (CTA). In particular, in connection with manufacturing CTA by oxidizing para-xylene in the presence of air containing oxygen and acetic acid solvent, the present invention relates to location relationship among a gas reactant feeding location to feed air containing oxygen, a liquid reactant feeding location to feed para-xylene and a location of an impeller, and also relates to a new oxidation reactor, a structure of which is changed. The oxidation reactor of the present invention controls location relationship among a gas reactant feeding (120) location, a liquid reactant feeding (110) location, a product exhausting (140) location, a reflux (130) location and a location of an impeller (90) in consideration of a flowing pattern of gas reactant and liquid reactant and a distribution of formed CTA, thereby performing a reaction without a dead zone in the reactor, thus manufacturing CTA in a higher forming rate than before.
