Abstract

La presente invencion se refiere a un proceso para calentamiento de un oxidizador secundario con vapor. Mas especificamente, la presente invencion se refiere a un proceso para calentamiento de un oxidizador secundario con vapor en un proceso para la produccion de un producto cristalizado. Un proceso para producir un producto cristalizado que comprende las siguientes etapas (a) la oxidacion en una zona de oxidacion primaria de una corriente de alimentacion de aromatico para producir una mezcla cruda de acido carboxilico; (b) oxidacion en una zona post oxidacion de la mezcla cruda de acido carboxilico en una zona post oxidacion en la presencia de vapor para formar un producto post oxidacion; (c) purificacion del producto post oxidacion para decolorizado del producto post oxidacion; y (d) cristalizacion en una zona de cristalizacion del producto post oxidacion para formar un producto cristalizado.
