Title:
PX OXIDATION REACTOR FOR PRODUCING TEREPHTHALIC ACID
Document Type and Number:
WIPO Patent Application WO/2010/081358
Kind Code:
A1
Abstract:
A PX oxidation reactor for producing terephthalic acid comprises a reactor shell (1). The reactor shell (1) is in tower shape and has an aspect ratio of 2.8~5. A distributed air intake device and a cyclonic air intake device are disposed at the bottom of the reactor shell (1). The distributed air intake device comprises outer ring air distributing tube (4) and inner ring air distributing tube (5), wherein the air distributing tubes (2) are in circle shape. The cyclonic air intake device comprises multiple cyclonic air intake tubes (3) which distributed around the vessel wall uniformly. Adopting combined air intake revolving device can force the fluid at the bottom of the reactor to rotate by adequate quantity of air, and the reactor has good air dispersion thus maintaining materials in normal suspension state. Moreover, adopting an aspect ratio between that of high temperature reactor and that of low temperature reactor can both avoid maldistribution phenomenon occurring in low temperature reactor and have less power consumption superior to high temperature reactor.
