A process is disclosed that relates to the removal of impurities and the recovery of mother liquor and wash filtrate from an oxidizer purge stream produced in the synthesis of carboxylic acid, typically terephthalic. More particularly, the process involves the removal of impurities and the recovery of a mother liquor and wash filtrate from an oxidizer purge stream and then routing the mother liquor and or wash filtrate to an oxidation zone.
La présente invention a pour objet un procédé d'élimination d'impuretés et de régénération de solution mère et de filtrat de lavage à partir d'un courant de purge oxydant produit au cours de la synthèse d~un acide carboxylique, en particulier téréphtalique. Ledit procédé a plus spécifiquement pour objet l~élimination d'impuretés et la régénération de solution mère et de filtrat de lavage à partir d'un courant de purge oxydant, suivies de la redirection de la solution mère et/ou du filtrat de lavage dans une unité d~oxydation.
