Pérdida de ozono en líneas de flujo poliméricas: PVC y silicona

Abstract

The aim of this present study was to evaluate the interaction between the ozone and the pipe material used for transporting it, usually of polymeric material, to then determine ozone loss during the process. For this purpose, a mixture of ozone-oxygen was transported through two types of pipes, PVC and silicone, from the ozone generator to the point of collection. The ozone concentration in the gas mixture and volumetric flow of the gas stream were varied for each experiment. The ozone mass flow was measured at the point of collection, applying the iodometric method by indirect titration. Ozone loss was observed in both pipes. These losses are associated with the chemical reaction between ozone and the pipe material, as well as to the ozone self-decomposition.
