As a service to readers who understand German, French English, the abstracts for the Refereed Papers in this issue Comments on Fluid-Intrusion Determining the Pore-Size Media by Peter R. Johnston:

Measurements for Distribution in Filter Pages 455-459

Stellungnahme zu Fkissigkeitsintrusionsmessungen zur Bestimmung der PorengroSenverteilung bei Filtermedien von F! R. Johnston Die PorengriiBenverteilungen bei Filtermedien werden durch Fltissigkeitsintrusionsmessungenermittelt. Zahlreiche Messungen lassen allerdings auf Verteilungen schlierjen, die nicht den Erwartungen entsprechen. Das vorliegende Referat untersucht, mit welcher Art von Verteilungen bei einem Filtermedium zu rechnen ist, das eine willkijrliche Anordnung von Partikeln enthalt bzw. bei einer feinporigen Membran, die nach der LbsungsmittelguBmethode erzeugt wurde. Das Referat fijhrt schlief3lich eine Reihe von Beispielan auf, bei denen eine bestimmte Art von Flijssigkeitsintrusion nicht die erwartete willkurliche Verteilung aufweist, wahrend die zweite den Erwartungen entspricht, solange bestimmte Bedingungen erfullt sind. (5 sn., 6 abb., 15 ref.) Commentaires sur les mesures par intrusion de fluid pour la determination de la distribution porometrique des medias filtrants par J. R. Johnson Les distributions porometriques dans les medias filtrants sont determinees par mesure d’intrusion de fluide. Mais beaucoup de mesures conduisent a des distributions qui different de ce qui est attendu. Cet article examine quelles sortes de distributions sont attendues dans un milieu contenant un ensemble aleatoire de fibres ou de particules, ou dans une membrane microporeuse produite par la methode d’inversion de solvant. Nude se poursuit en montrant des exemples oti un type de mesure par penetration fluide echoue a montrer la distribution porometrique attendue alors qu’un autre type reussit, pour autant que certaines conditions soient realisees.(5 pags., 6 figs., 15 refs.) Comentarios sobre medidas con la entrada de fluido, para determinar la distribution de tamafios de poros en medios filtrantes. por P R. Johnston Se determinan las distribuciones de tamaiios de poros en medios filtrantes por medidas de entrada de fluido. Muchas de indican distribuciones diferentes de estas medidas expectation. Esta ponencia resena 10s tipos de distribuciones esperadas en un medio de cojunto aleatorio de fibras 6 particulas, 6 en una membrana microporosa, producida de metodo de vaciar con solventes. Se muestran ejemplos, en 10s cuales una medida no revela la distribution aleatoria esperada; otro exhibe este fenomeno mientras se llena 10s requisitos necesarios. (5 pags., 6 figs., 15 refs.) High Temperature Filtration in the Process Industry by Dr. -Ing Wolfgang Peukert: Pages 461-464 Hochtemperaturfiltration in der weiterverarbeitenden lndustrie von Dr. Ing. Wolfgang Peukert Die Hochtemperaturfiltration bietet bei der industriellen Weiterverarbeitung verschiedene Vorteile im Hinblick auf die Erhohung der Verarbeitungseffizienz, die Warmertickgewinnung und den Schutz von Geraten und Anlagen. In der weiterverarbeitenden lndustrie gibt es eine Reihe von interessanten und anspruchsvollen Anwendungsgebieten. Das vorliegende Referat enthalt eine Beschreibung der experimentellen Untersuchungen mit einem Keramikund zwei Metall-HochtemperaturFilterelementen (gesintertes Vlies und Gewebebeutel). Alle drei Arten von Filterelementen sind auf einer Pilotanlage im Labor bei verschiedenen Filtrationsgeschwindigkeiten bis zu 2.5 m/Minute und Temperaturen zwischen Raumtemperatur und 600°C getestet worden. Betriebstechnische Unterschiede zwischen den

or Spanish better than follow in these languages.

Keramik- und Metallfiltermedien werden von Messungen des sowie des Restdruckabfalls der Druckabfallverhaltens Filterelemente abgeleitet. In Bezug auf Metallfilterelemente ist ein zusatzlicher Parameter zu berucksichtigen, d.h. die Anderung der Struktur des Filtermediums im Verhaltnis zur Temperatur. Zur Sicherstellung eines auf lange Sicht stabilen Betriebs van Hochtemperatur-Kerzenfiltern ist ein gut ausgelegtes Pulsostrahl-Regenerierungssystem von ausschlaggebender Bedeutung. Gravimetrisch und optisch durchgefuhrte Reingasmessungen zeigen bei Vliesstrukturen aul3erst niedrige Reingaskonzentrationen im Bereich von nur wenigen pg/m3. Hijhere Werte im Bereich von IO mg/m3 wurden unter Verwendung von gewebten Metallbeutein erzielt. Gewebte Metallbeutel sind urn einiges billiger als gesinterte Metallvlieselemente.(4 sn., 6 abb., 4 tab., 3 ref.) Filtration a haute temperature dans I’industrie des procedes par Dr. Ing. Wolgang Peukert. La filtration a haute temperature dans les processus industriels offre divers avantages comme I’augmentation de I’efficacite du pro&de, la recuperation de chaleur et la protection des installations. Des applications extremement interessantes sont trouvees dans I’industrie des procedes. Cet article decrit les recherches experimentales effect&es avec un ceramique et avec deux types d’elements filtrants metalliques pour hautes temperatures (structure de molleton fritte et poches tissees). Les trois elements ont ete testes sur un filtre pilote de laboratoire a differentes vitesses de filtration jusqu’a 2.5 m/min et a des temperatures variant entre la temperature ambiante et 600°C. Les differences de comportement entre ceramique et medias filtrants metalliques sont deduites des mesures de la montee de la chute de pression ainsi que de la chute de pression residuelle des elements filtrants. Dans le cas des elements filtrants metalliques, un parametre additionnel doit etre consider& a savoir les modifications de la structure du media avec la temperature. Pour un fontionnement stable a long terme des filtres a bougies a haute temperature, un systeme de regeneration a jet pulse de bonne conception est essentiel. Des measures gravimetriques et optiques operees sur gaz epure montrent pour les structures des molletons des concentrations extremement basses de I’ordre de quelques pg/m3. Des valeurs plus elevees de I’ordre de 10 mg/m3 ont ete obtenues avec les poches en metal tisse. Celles-ci sont raisonnablement moins cheres que les elements metalliques frittes. (4 pags., 6 figs., 4 tab., 3 refs.) Filtacion a alta temperatura de gases en las industrias de proceso por Dr. Ing. Wolfgang Peukert Filtration a alta temperatura de gases en 10s procesos industriales ofrece ventajas en terminos de eficiencia creciente, recuperacion de calor, y protection de instalaciones de planta. Se hallan aplicaciones muy interesantes y absorbentes en las industrias de proceso. Este articulo presenta investigaciones experimentales con elementos de ceramic0 a alta temperatura y dos tipos de metal (vellon fusionado y sacos tejidos). Se han examinado en un laboratorio 10s tres tipos de elementos en un filtro piloto, con diferentes velocidades de filtration hasta 2.5 m/min, y temperaturas en el rango entre ambiente y 600°C. Se derivan las diferencias entre medios filtrantes de ceramic0 y de metal, de medidas de la caida de presion, y de la caida residual de presion de 10s elementos filtrantes. En el case de elementos de metal, se debe considerar un pardmetro adicional - el cambio de estructura del media con temperatura. Una cosa esencial para el funcionamiento firme a la larga de filtros de vela a alta temperatura, es un sistema bien arreglado de regeneration con chorro pulsado. Medidas por metodos gravimetricos y opticos, de gas limpio dan, con las estructuras vellon, concentraciones muy bajas de gas limpio, en la gama de unos pocos pg/m3. Se han obterido valores mas altos (unos 10 mg/m3) con sacos de metal tejido. Los sacos tejidos son was baratos que elementos de metal fusionado. (4 pags., 6 figs., 4 tab., 3 refs.)
