Das Hauptpatent betrifft Füllkörper für Stoffaustauschkolonnen, bestehend aus einem Gewebe, dessen Schuß- und Kettfäden gleichen oder verschiedenen Durchmesser aufweisen, der höchstens 0,6 mm beträgt, wobei das Gewebe mindestens in Schuß- oder Kettfadenrichlung so ausgebildet ist, daß das Produkt eines sloffabhängigen Faktors A und eines strukturabhängigen Faktors B mindestens den Wert 38 hat, wobei der Faktor A gebildet ist aus dem Quotienten der Oberflächenspannung der Flüssigkeit gegen ihren Dampf (dyn/cm) zu der Flüssigkeitsdichte (p/cm3), multipliziert mit dem cos des Benelzungswinkels, und der Faktor B aus dem Verhältnis des Fadendurchmessers d zur lichten Maschenweite α gebildet ist.The main patent relates to packing for mass transfer columns, consisting of a fabric, the weft and warp threads of which have the same or different diameter, which is at most 0.6 mm, the fabric being designed at least in the weft or warp thread direction so that the product of a sloff-dependent factor A and a structure-dependent factor B has at least the value 38, where the factor A is formed from the quotient of the surface tension of the liquid against its vapor (dyn / cm) to the liquid density (p / cm 3 ), multiplied by the cos of the wetting angle, and the factor B is formed from the ratio of the thread diameter d to the clear mesh size α .
Kolonnen mit solchen Füllkörpcrn können zur Durchführung von Destillationen, Rektifikationen, Absorptionen, Extraktionen, zur Durchführung chemischer Reaktionen, wie ζ. Β Abtrennung isotoper Elemente, aus einem Stoff auf Grund einer chemischen Austauschreaktion u. dgl. verwendet werder.Columns with such packing elements can be used to carry out distillations, rectifications, Absorptions, extractions, to carry out chemical reactions, such as ζ. Β Separation isotopic Elements made of a substance due to a chemical exchange reaction and the like are used.
Werden Füllkörper aus Gewebe der vorstehend beschriebenen Art in derartigen Kolonnen verwendet, so müssen diese Füllkörper vor Betrieb nicht geflutet werden, da diese Gewebe selb-.tbenctzend sind.If packing made of fabric of the type described above is used in such columns, This means that these fillers do not have to be flooded before operation, as these fabrics are self-contained.

ergibt bei bestimmtem A und d zugleich einen Maximalwert für den Abstand α für die Maschenweite. Die Werte für die Dichte der Flüssigkeil und der Oberflächenspannung gegen die Dampfphase sind aber oft mit einer Unsicherheit behaftet. Man begegnet dieser Unsicherheit mit einer Verkleinerung Scr Maschenweite a. Damit wird der Zahknwert des Produktes A ■ B größer und hierdurch die Voraussetzung für die Selbst benetzung des Gewebes günstiger. Wenn die lichte Maschenweile jedoch sehr klein wird, bewirkt dieses einen unter Umständen stark verminderten Wirkungsgrad für den Stoffaustausch.at a certain A and d simultaneously results in a maximum value for the distance α for the mesh size. However, the values for the density of the liquid wedge and the surface tension against the vapor phase are often fraught with uncertainty. This uncertainty is countered by reducing the size of the mesh size a. This increases the tooth value of the product A ■ B and thus the prerequisite for the self-wetting of the tissue is more favorable. However, if the clear mesh width becomes very small, this may result in a greatly reduced efficiency for the mass transfer.

Daß das mit der Erfindung angestrebte Ziel durch Einhaltung der vorstehenden Forderung erreicht wird, konnte durch experimentelle Untersuchungen an einer Reihe von Geweben bestätigt werden.is guaranteed by a good exchange of substances. That the aim pursued by the invention through Compliance with the above requirement is achieved through experimental investigations a number of tissues can be confirmed.
In einem Ausführungsbeispiel der Erfindung sollen die Abmessungen eines Gewebes für die Füllkörper einer Rektifizkrkolonne bestimmt werden, in der ein Gemisch vi η cis-Dekalin/trans-Dekalin bei 100 C getrennt werden soll. Für die genannte flüssigkeit ist die DichteIn one embodiment of the invention, the dimensions of a fabric for the packing a rectification column can be determined in the a mixture vi η cis-decalin / trans-decalin at 100 ° C should be separated.

Setzt man diese Werte in die angegebene Formel A ■ B 2: 38 ein, so ergibt sich daraus, dali /ur Erreichung einer Selbst benetzung des Gewebes der Quotient ' ^ 1,2 sein muß.If these values are inserted into the given formula A · B 2: 38, it follows that the quotient must be '^ 1.2 to achieve self-wetting of the tissue.
Um einen guten Stoffaustausch zu erreichen, soll gemäß der vorliegenden Erfindung die Beziehung d- ^ 2,5 erfüllt sein.In order to achieve a good mass transfer, the relationship d - ^ 2.5 should be fulfilled according to the present invention.

Bei einem Drahtdurchmesser d = 0,016 cm ergibt sich dann für a — 0,010 cm.If there is an uncertainty factor, the ratio of d to α approximately 1.6 will be chosen in this ./ case. With a wire diameter d = 0.016 cm, the result for a is - 0.010 cm.
Während durch die eingangs angegebene Beziehung A ■ B ^ 38 bei gegebenem A und d eine Grenze für die größte Maschenweite α gegeben wird, bei der noch eine Selbstbenetzung des Gewebes verwirklicht werden kann, so gibt die vorliegende Erfindung bei gegebenem d eine untere Grenze für die Maschenweite α an, bei der lichte Maschenöffnungen von einer Größe gewährleistet sind, bei denen ein guier Stoffaustausch, in dem die Maschenöffnungen bedeckenden Flüssigkeitsfilm mit der Dampfphase von beiden Seiten her erfolgen kann. While the relationship A ■ B ^ 38 given at the beginning, given A and d , gives a limit for the largest mesh size α at which self-wetting of the fabric can still be achieved, the present invention gives a lower limit for the given d Mesh size α at which clear mesh openings of a size are guaranteed in which a good exchange of substances, in which the liquid film covering the mesh openings can take place with the vapor phase from both sides.
Vorteilhaft sind die Füllkörper so in der Kolonne angeordnet, daß die Kapillarwirkung in der Horizontalen auftritt, d. h., der engste Maschenabstand a soll zwischen zwei übereinanderliegenden horizontalen Drähten bzw. Fäden liegen.The packing elements are advantageously arranged in the column in such a way that the capillary action occurs horizontally, ie the narrowest mesh spacing a should lie between two horizontal wires or threads lying one above the other.
