Adsorption Processes in Gas Mask Filter Canisters: Practical Aspects, New Materials and Modeling
- 1.6k Downloads
Three topics are addressed related to adsorption processes in gas mask filter canisters. In the first section “practical aspects” two items are addressed: (a) the influence of the flow pattern, i.e. a breathing or pulsating flow versus continuous flow, on the breakthrough behavior; and (b) the risk of desorption: the possibility that adsorbed contaminants are released from the filter. The second section “new materials” deals with the use of carbon monoliths. The third section “modeling” discusses a gas mask model that has been implemented in a software tool that simulates chemical and biological incidents.
Keywords: Adsorption, gas mask, carbon monoliths, modeling, incidents.
