Book excerpt: Cette étude s'inscrit dans le cadre de l'amélioration des connaissances liées à l'évaporation d'aérosols liquides semi-volatils collectés sur des filtres à fibres. Le phénomène d'évaporation d'aérosols collectés sur médias fibreux induit des problèmes de sécurité avec notamment une surexposition des salariés aux vapeurs, à l'aval des systèmes généraux de filtration de l'air. De plus, lors des contrôles des concentrations atmosphériques des aérosols, l'évaporation induit une sous-estimation de la phase particulaire de l'aérosol prélevé qui est problématique en termes de prévention de l'exposition. L'objectif de ces travaux a donc été de produire de nombreux résultats expérimentaux afin, d'une part, de compléter les rares présents dans la littérature et, d'autre part, d'améliorer les modèles théoriques développés précédemment. Deux approches expérimentales ont été menées afin d'identifier le processus d'évaporation d'un aérosol collecté. La première, nommée approche globale, permet de suivre l'évaporation de l'aérosol par la quantification des vapeurs à l'aval du filtre, au cours du temps. La seconde, nommée approche microscopique, étudie l'évaporation de gouttes collectées sur les fibres d'une fibre à l'échelle microscopique. Les deux approches réalisées lors de ces travaux s'accordent sur le fait que l'évaporation d'un aérosol liquide semi-volatil ne peut être modélisée par les modèles proposés par la littérature. Des hypothèses ont été avancées afin d'expliquer la divergence de cinétique d'évaporation entre la théorie et les expérimentations.

Book excerpt: Filtration of aerosols is omnipresent in our daily lives, in areas as diverse as health, the protection of people and the environment, and air treatment inside buildings. However, the collection of particles within a filter media is not, contrary to popular belief, linked to a simple screen effect. The phenomena involved are much more complex and require the consideration of aerosol interactions, filter media and process conditions to select the best fiber filter for a given application. Aerosol Filtration, book for students, hygiene or process engineers, fibrous media manufacturers, designers, and filtration system suppliers or users addresses the filtration of aerosols in six chapters. These chapters cover physics and aerosol characterization, the fibrous media, and efficiency and filter clogging by solid or liquid aerosols, with special attention to the filtration of the nanoparticles. - Analyses the behavior of fibrous media against solid and liquid aerosols - Presents models of efficiency and pressure drop - Introduces computing elements for estimating the lifetime of filters - Provides guidance for designing filters and predicting their behavior over time
