Eine neue Packung für die Vakuumrektifikation

Abstract: Die Chemische Werke Hiils AG gibt als maximale Temperaturbelastung 140°C an. Sie ist aberim Dauerbetriebstark abhangig von der Zusammensetzung der angreifenden chemischen Produkte. Es sollten also in jedem Anwendungsfall beide Beanspruchungen gemeinsam kritisch erwogen werden. Ferner kann die Haltbarkeit einer Auskleidung leiden, wenn die beanspruchende Substanz Spuren von Medien enthalt, gegen die der Werkstoff nicht bestandig ist. Die Verarbeiter haben eine auf etwa zehnjahriger Erfah-rung basierende Bestand… Show more

“…For many years packed columns consisted of randomly dumped packings almost exclusively, with occasional applications of regularly stacked packings or pads of woven or knitted wire. In the late 1960s a partial trend away from random packings began when a special structured packing made of wire gauze was introduced by Sulzer Brothers in Switzerland (64). The indicated advantages of the structured packings were high mass-transfer efficiency and very low pressure drop.…”

“…A worthwhile new correlation for packed bed flooding appeared (65), and another paper dealt with the general aspects of gas-liquid flow in countercurrent contacting equipment (103). A new packing of the grid-type, suitable for vacuum service, was introduced (89).…”

“…Pressure drops have to be maintained at a reasonable level, and large specific areas can be offered with liquid flows fixed below the flooding capacity of the column. For the sake of intense transfer rates, structured packings have been developed, in particular to increase the effectiveness of gas-liquid separation in distillation towers (Sperandio et al, 1965). Such packings have been used for absorption of VOCs or CO 2 (Brunazzi and Paglianti, 1997;Aroonwilas and Tontiwachwuthikul, 1998;Dang Van et al, 1998;Wang et al, 2001), gas-liquid desorption, e.g.…”
