Abstract:
1. An apparatus for making peroxycarboxylic acid, comprising: (a) a first reagent vessel configured for containing hydrogen peroxide; (b) a second reagent vessel configured for containing a liquid carboxylic acid composition; (c) a reaction mixture conduit; (d) a first reaction catalyst column configured for catalyzing a reaction of the carboxylic acid composition and the hydrogen peroxide to produce peroxycarboxylic acid; (e) a first pretreatment column comprising a removable pretreatment cartridge and configured for removing metal ions from only the carboxylic acid composition; (f) a reagent conduit; (g) a peracid conduit; and (h) a safety system configured to provide a signal to allow intervention to avoid unsafe conditions due to active metal ion catalyzed decomposition of hydrogen peroxide, the safety system comprising
