Abstract

Se da a conocer u proceso y equipamiento optimizado para llevar a cabo la oxidacion en fase líquida de un compuesto oxidable. Tal oxidacion en fase líquida se lleva a cabo en un reactor de columna de burbujeo que contempla una reaccion altamente eficiente a temperaturas relativamente bajas. Cuando el compuesto oxidado es para-xileno y el producto de la reaccion de oxidacion es ácido tereftálico en bruto (CTA). Proceso que comprende oxidar un compuesto oxidable en fase líquida y reactor de columna de burbujeo. Reivindicacion 29. En un reactor de columna de burbujeo para hacer reaccionar una corriente predominantemente en fase líquida y una corriente predominantemente en fase gaseosa, la mejora que comprende: una envolvente de recipiente que define una zona de reaccion que se extiende a lo largo de un eje central, en donde dicha zona de reaccion tiene un extremo normalmente inferior y un extremo normalmente superior espaciados entre sí por una distancia axial máxima (L), teniendo dicha zona de reaccion un diámetro máximo (D), en donde dicha zona de reaccion tiene una relacion L:D de al menos aproximadamente 6:1; y una o más aberturas para gas para la descarga de dicha corriente en fase gaseosa dentro de dicha zona de reaccion, estando la mayoría del área abierta acumulada definida por la totalidad de dichas aberturas para gas ubicada dentro de aproximadamente 0,25 D de dicho extremo normalmente inferior de dicha zona de reaccion.An optimized process and equipment for carrying out the oxidation in the liquid phase of an oxidizable compound is disclosed. Such liquid phase oxidation is carried out in a bubble column reactor that contemplates a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product of the oxidation reaction is crude terephthalic acid (CTA). Process comprising oxidizing a liquid phase oxidizable compound and bubble column reactor. Claim 29. In a bubble column reactor for reacting a predominantly liquid phase stream and a predominantly gas phase stream, the improvement comprising: a vessel envelope defining a reaction zone that extends along a central axis, wherein said reaction zone has a normally lower end and a normally upper end spaced apart by a maximum axial distance (L), said reaction zone having a maximum diameter (D), wherein said reaction zone has an L: D ratio of at least about 6: 1; and one or more gas openings for the discharge of said gas phase current within said reaction zone, the majority of the accumulated open area being defined by all said gas openings located within approximately 0.25 D of said end normally lower of said reaction zone.
