Abstract

Cette installation (10) comprend une installation principale (14) de production de peroxyde d'hydrogène à une concentration d'utilisation, agencée sur le site même de l'unité de traitement (12), et une installation de secours (16), destinée à alimenter l'unité de traitement (12) en cas d'arrêt de l'installation principale (14). L'installation de secours comporte une réserve (18) de peroxyde d'hydrogène à une concentration de stockage supérieure à la concentration d'utilisation et des moyens (20) de dilution du peroxyde d'hydrogène stocké, raccordés entre la réserve (18) et l'unité de traitement (12) permettant de réduire la concentration de stockage du peroxyde d'hydrogène jusqu'à la concentration d'utilisation.
