Title
(EN) METHOD AND APPARATUS FOR THE TREATMENT OF EFFLUENTS FROM PRODUCTION PLANTS OF EPOXY COMPOUNDS
(FR) PROCÉDÉ ET APPAREIL POUR TRAITER DES EFFLUENTS PROVENANT D'INSTALLATIONS DE PRODUCTION DE COMPOSÉS ÉPOXY
Abstract
(EN)
The invention relates to a process of abatement of the organic content of a depleted brine coming from epoxy compound production involving a vapour stripping step and a mineralisation with hypochlorite in two steps, at distinct pH and temperature conditions.
(FR)
L'invention concerne un procédé de réduction de la teneur organique d'une solution de saumure appauvrie provenant de la production de composés époxy qui implique une étape de strippage à la vapeur et deux étapes de minéralisation à l'hypochlorite dans des conditions de pH et de température distinctes.
