A liquid-gas phase reactor system including a slinger located in an upper section (headspace region) of a reaction vessel. The slinger comprises an upper horizontal surface including a plurality of vertically raised vanes extending radially outward along a curved path which effectively distribute liquid about the reactor vessel. A method for conducting an oxidation reaction using a liquid-gas phase reactor system is also disclosed. The disclosed reactor system and method have a broad range of applications but are particularly suited for the production of terephthalic acid.

Cette invention concerne un système réacteur à phase liquide-gaz comprenant un anneau gicleur placé dans une section supérieure (zone de vide) d'une cuve de réaction. L'anneau gicleur présente une surface horizontale supérieure comprenant plusieurs aubes orientées verticalement et s'étendant radialement vers l'extérieur le long d'un trajet incurvé permettant la répartition efficace du liquide autour de la cuve de réaction. Cette invention concerne un procédé permettant de mettre en oeuvre une réaction d'oxydation au moyen du système réacteur à phase liquide-gaz. Le système réacteur à phase liquide-gaz et le procédé susmentionnés peuvent être utilisés dans une large gamme d'applications mais ils conviennent plus particulièrement à la production d'acide térephtalique.
