Description
Bei den beispielsweise für die Destillation und Rektifikation zur Inkontaktbringung von Flüssigkeiten und Gasen verwendeten Kontaktsäulen ist es bekanntlich zweckmäßig, den Kontakt zwischen Flüssigkeit und Gas nach Möglichkeit zu fördern und zu diesem Zweck die Flüssigkeit so weitgehend als möglich in einen Schaum zu verwandeln, dessen Blasen durch das Gas gebildet werden.For example, for distillation and rectification for bringing into contact Liquids and gases used contact columns, it is known to be expedient to the To promote contact between liquid and gas whenever possible and for this purpose to transform the liquid as much as possible into a foam, its bubbles formed by the gas.
Nun läßt sich z. B. bei den für die Rektifikation der flüssigen Luft verwendeten Säulen eine bessere Wirkung erzielen, wenn gemäß der Erfindung im oberen Teil, wo sich die verhältnismäßig stickstoffreichen Gase und Flüssigkeiten befinden, die Teller so angeordnet werden, daß sie mehr Flüssigkeit als in den anderen Teilen enthalten. Dieses läßt sich leicht dadurch erzielen, daß man entweder die Höhe des Überlaufstandes der Flüssig-Now z. B. in the columns used for the rectification of liquid air achieve a better effect if according to the invention in the upper part, where the relatively nitrogen-rich gases and liquids are located on the plates that they contain more liquid than in the other parts. This leaves can easily be achieved by either determining the height of the overflow level of the liquid
ao keit in jedem Teller oder die Oberfläche des Tellers oder beides zusammen erhöht; man wird somit beispielsweise den Durchmesser der Rektifikationssäule von ihrem unteren Teil an bis zu ihrem oberen Teil entweder allmählich oder stufenweise größer machen, während bisher alle Teile einer Säule, in welcher flüssige Luft oder mehr oder weniger sauerstoff- oder stickstoffreiche Flüssigkeiten unter ungefähr gleichem Druck rektifiziert werden, mit demselben Durchmesser ausgeführt werden.ao increased speed in each plate or the surface of the plate or both together; man thus, for example, the diameter of the rectification column is different from its lower one Make part up to their upper part either gradually or gradually larger, while so far all parts of a column, in which liquid air or more or less oxygen- or nitrogen-rich liquids are rectified under approximately the same pressure, be made with the same diameter.
Die durch diese Anordnung erhaltene bessere Wirkung dürfte auf den Unterschied in dem Zustand zwischen dem Schaum der stickstoffreichen Teile und dem Schaum der sauerstoffreichen Teile zurückzuführen sein; im allgemeinen soll die Flüssigkeitsmenge auf jedem Teller desto größer sein, je kleiner die Oberflächenspannung und je höher die Viskosität der Flüssigkeit ist.The better effect obtained by this arrangement is believed to be due to the difference in that State between the foam of the nitrogen-rich parts and the foam of the oxygen-rich Parts to be attributed; in general, the amount of fluid should be on each The larger the plate, the smaller the surface tension and the higher the viscosity the liquid is.
