Absorption of hydrophobic volatile organic compounds by a rotating packed bed / Chia-Ying Chiang in Industrial & engineering chemistry research, Vol. 51 N° 27 (Juillet 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 27 (Juillet 2012) . - pp. 9441-9445 Titre : Absorption of hydrophobic volatile organic compounds by a rotating packed bed Type de document : texte imprimé Auteurs : Chia-Ying Chiang, Auteur ; Yi-Ying Liu, Auteur ; Yu-Shao Chen, Auteur Année de publication : 2012 Article en page(s) : pp. 9441-9445 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Packed bed Volatile organic compound Résumé : The high development of industries leads to significant amount of waste hydrophobic volatile organic compounds (VOCs), and these have caused serious environmental concerns. Because of the physical properties of the hydrophobic VOCs, a hydrophobic absorbent is needed in order to make the process more efficient if absorption is considered. However, most of these absorbents have high viscosities which leads to a low mass transfer coefficient. Thus, a cross-flow rotating packed bed (RPB) was evaluated for the feasibility of absorbing the hydrophobic VOCs, xylene, and toluene, by silicon oil, a model hydrophobic absorbent. The result shows that the absorption percentage could be up to 98% within a second contact of liquid and gas.
