  • Auxiliary filter for enhanced chemical protection
    Patent number: 11794140
    Abstract: A process and device for enhancing the chemical protection capability of a collective protection filter whereby the process stream exiting the collective protection filter is passed through an Auxiliary Filter. The auxiliary filter containing an ammonia removal media, such as zirconium hydroxide impregnated with zinc chloride (ZnCl2/Zr(OH)4), an oxidizing media, preferably zirconium hydroxide impregnated with potassium permanganate (KMnO4/Zr(OH)4), and a methyl bromide removal media, preferably activated carbon impregnated with triethylenediamine (TEDA/carbon). The auxiliary filter and process are configured to remove toxic industrial chemicals including NH3, NOx (mixtures of NO and NO2) and CH2O, and CH3Br.
