Verfahren zum Auswaschen und Wiedergewinnen von flüchtigen Lösungsmitteln, wie
Benzol, Benzin, Äther usw., aus diese enthaltenden Gasen.
Es ist bereits bekannt, flüchtige Stoffe, wie Benzol, Benzin, Äther, Alkohol, Azeton usw., aus sie enthaltenden Gasgemischen, wie Koksofengas, Abgase von Kunstseidefabriken, Erdgase usw., dadurch zu gewinnen, dass man diese Gase mit hydrierten Naphthalinkohlenwasserstoffen, wie Tetralin oder
EMI1.1
und die flüchtigen Stoffe durch Destillation unter Rückgewinnung des Waschmittels freimacht.
Der Gegenstand der vorliegenden Erfindung betrifft ein Wasch-und Wiedergewinnungsverfahren für solche Gase, wobei an Stelle der hydrierten Naphtalinkohlenwasserstoffe die Hydrierungsprodukte der Phenole, z. B. das unter der Bezeichnung Hexalin in den Handel gebrachte Hexahydrophenol, in gleicher Weise verwendet werden.
Diese Stoffe vereinigen infolge ihrer Konstitution die Eigenschaften der Naphtalinkohlenwasserstoffe und der Phenole und sind daher besonders dann geeignet, als Waschflüssigkeiten zu dienen, wenn es sich darum handelt, Gemische von flüchtigen Stoffen aus den sie enthaltenden Gasen auszuwaschen.
Ihre Verwendung empfiehlt sich daher in vielen Fällen, in denen man bisher mit einem Waschmittel nicht das Auslangen fand und entweder auf vollständige Rückgewinnung eines Bestandteiles verzichten musste oder aber zur Anwendung mehrerer Waschmittel gezwungen war.

Methods for washing out and recovering volatile solvents such as
Benzene, gasoline, ether, etc., from gases containing them.
It is already known that volatile substances, such as benzene, gasoline, ether, alcohol, acetone, etc., from gas mixtures containing them, such as coke oven gas, exhaust gases from rayon factories, natural gases, etc., are obtained by treating these gases with hydrogenated naphthalene hydrocarbons, such as Tetralin or
EMI1.1
and clears the volatiles by distillation to recover the detergent.
The subject matter of the present invention relates to a scrubbing and recovery process for such gases, in which the hydrogenation products of the phenols, e.g. B. the hexahydrophenol marketed under the name Hexalin, can be used in the same way.
As a result of their constitution, these substances combine the properties of naphthalene hydrocarbons and phenols and are therefore particularly suitable for use as scrubbing liquids when it comes to washing mixtures of volatile substances from the gases they contain.
Their use is therefore recommended in many cases in which one detergent was previously not sufficient and either had to forego complete recovery of one component or was forced to use several detergents.
