(57) Abstract :
Disclosed is an optimized process and apparatus for more afficiently a economically carrying out the liquid-phase oxidation of an
oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient
reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is
crude tefephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be
employed if the CTA were formed by a conventional high-temperature oxidation process.
