A process for preparing aromatic carboxylic acids by the exothermic liquid-phase oxidation reaction of an aromatic feedstock compound, wherein energy is efficiently recovered from the exothermic oxidation reaction, particularly by the use of a high efficiency distillation column for the removal of the carboxylic acid solvent and by the use of an expander for energy recovery from the high pressure offgas.
Procédé de préparation d'acides carboxyliques aromatiques par une réaction exothermique d'oxydation en phase liquide d'un composé aromatique d'apport au cours de laquelle l'énergie de la réaction exothermique d'oxydation est efficacement récupérée notamment du fait de l'utilisation d'une colonne de distillation à haut rendement pour extraire les solvants de l'acide carboxylique et d'un expanseur pour récupérer l'énergie des effluents gazeux à haute température.
