Enhancing the throughput of membrane emulsification techniques to manufacture functional particles / Qingchun Yuan in Industrial & engineering chemistry research, Vol. 48 N° 19 (Octobre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 19 (Octobre 2009) . - pp. 8872–8880 Titre : Enhancing the throughput of membrane emulsification techniques to manufacture functional particles Type de document : texte imprimé Auteurs : Qingchun Yuan, Auteur ; Nita Aryanti, Auteur ; Gemma Gutiérrez, Auteur Année de publication : 2009 Article en page(s) : pp. 8872–8880 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Membrane  emulsification  system  Cross-flow  Rotating  membrane  technology Résumé : Formulation technologies increasingly demand the manufacture of droplets with user-controlled size and size distributions for applications in emulsions, capsules, and semisolid particulates. These are used in various functional consumer products. This paper introduces methods to enhance throughput for two types of membrane emulsification system, using cross-flow and rotating membrane technology. Modification of the interaction between the dispersed phase and the surface of the membrane, the inner wall of the pores (through control of hydrophobicity), pore orientation, and pore shape is demonstrated to increase emulsion droplet productivity. Such methods can also be deployed in the production of capsule materials using emulsion precursors. The possible mechanisms underlying the enhancements are discussed. It is concluded that noncircular pores can offer significant process benefits for the production of uniform droplets and semisolid particulates. It is demonstrated that the droplet formation rate can be doubled through optimization of the orientation of noncircular pores in a rotating membrane process.
