Abstract EN:
Faced with the demand of limiting the energy consumption, indoor air recycling has become an important matter. But the negative side of air recycling, pollutant accumulation and risk of inter contamination, requires an air treatment. Among available process for volatile organic compounds (VOCs), one pairing adsorption onto activated carbon and UV photocatalysis is proposed. We focus on the unknown aspect of this process, the combined influence of temperature and humidity. Our objectives are: to apprehend the treatment during operational changes and fluctuations of conditions; and to optimize a simulation program which can assist the conception phase of an industrial treatment unit.
