✦ Synopsis


The definition of efficiency in a process of separation is discussed, and the various requirements that should be fulfilled by such a definition are enumerated. The formulae so far proposed in literature for expressing the separation efficiency are reviewed in the light of these requirements. A formula put forward by the author is found to satisfy them all. Its application is illustrated by means of two examples. R&umS--La definition du rendement d'un procede de separation est discutde, et les differentes exigences auxquelles doit r&pondre une telle definition sont CnumCmes. Les formules propodes jusqu'a present dans la litterature exprimant le rendement de separation sont consider6es tenant compte de ces exigences. Une formule mis au point par l'auteur s'est month satisfaisante sous tous les aspects. Deux exemples sont don&s pour illustrer l'application de la formule. Zusammenfassung-Es wird die Definition der Wirksamkeit eines Trennprozesses diskutiert und es werden die verschiedenen Forderungen aufgefiihrt, denen eine solche Definition geniigen muss. Unter diesem Gesichtspunkt werden die in der Literatur vorgeschlngenen Gleichungen betrachtet. Es zeigt sich, dass eine vom Autor mitgeteilte Formel alle aufgestellten Forderungen erfiillt. Ihre Anwendung wird an zwei Beispielen erliiutert. 1.
