Definitions

  • the retention time for the aqueous mixture within the reaction chamber should be generally sufficient to achieve the desired degree of oxidation. In some embodiments, the retention time is above about one hour and up to about eight hours. In at least one embodiment, the retention time is at least about 15 minutes and up to about 6 hours. In one embodiment, the aqueous mixture is oxidized for about 15 minutes to about 4 hours. In another embodiment, the aqueous mixture is oxidized for about 30 minutes to about 3 hours.
  • bench scale wet oxidation tests were performed in laboratory autoclaves.
  • the autoclaves differ from the full scale system in that they are batch reactors, where the full scale unit may be a continuous flow reactor.
  • the autoclaves typically operate at a higher pressure than the full scale unit, as a high charge of air must be added to the autoclave in order to provide sufficient oxygen for the duration of the reaction.
  • the results of the autoclave tests provide an indication of the performance of the wet oxidation technology and are useful for screening operating conditions for the wet oxidation process.

Abstract

L'invention concerne un système et un procédé pour le traitement de courants de traitement. Un catalyseur médie un procédé d'oxydation humide à températures élevées et pressions élevées pour le traitement d'au moins un constituant indésirable dans un mélange aqueux. Un catalyseur peut être choisi pour sa solubilité à un niveau de pH détecté du mélange aqueux. En variante, un niveau de pH du mélange aqueux peut être réglé pour solubiliser un catalyseur choisi et/ou maintenir le catalyseur choisi sous une forme soluble. Un dispositif de commande en communication avec un capteur de pH peut être configuré pour générer un signal de commande pour régler le niveau de pH du mélange aqueux en réponse au capteur de pH enregistrant un niveau de pH hors d'une plage de solubilité de pH prédéterminée pour un catalyseur choisi.
