Description

  

  



  Verfahren zum Verhindern von Korrosionen.



   Im Hauptpatent ist ein Verfahren zum Verhindern von Korrosionen beschrieben, nach welchem saure Dampfe und Gase nach dem Austritt aus der Flüssigkeit durch Mischung mit einer Base wenigstens chemisch neutral gemacht werden.



   Die Wirksamkeit dieser Neutralisation hängt ab von der innigen Mischung der Base mit den Dämpfen oder Gasen. Da es sich meistens um sehr geringe   Quantitäten    Base handelt, die eingeführt werden müssen, so kann es Schwierigkeiten bereiten, eine gute Verteilung in den Dämpfen oder Gasen zu erzielen. Um diese Verteilung zu erleichtern, wird gemÏ? vorliegender Erfindung die Base mit Zusatzdampf gemischt, der durch sein grösseres Volumen eine Verteilung der Base eventuell   unterZerstäubung derselben bewirkt.   



  Dieser Zusatzdampf kann in eine   Vorrich-    tung zur Einführung der Base eingeführt werden. Bei Vorhandensein eines   Brüden-      dampfkompressors    nach Fig. 4 des   Eaupt-    patentes entnimmt man mit Vorteil diesen   Zusatzdampf    der ersten Stufe a-uf der Saugseite, also zwischen Leitung 30 und   33.    Sollte der Druck nicht genügen, so kann man Dampf aus einer beliebig höheren Stufe des Kompressors entnehmen.   Der Zusatzdampf    ist in dieser Kombination nicht verloren, sondern beschreibt einen Kreislauf durch den Kompressor.



   In beiliegender Zeichnung wird beispielsweise das vorliegende Verfahren mit Benützung von   Dampfzusatz    aus einer Stufe eines Brüdendampfverdichters schematisch dargestellt. Aus Apparat 1 gehen die Br den durch Rohr 2   und Mischapparat    3 in den   Brüden-      dampfverdichter    4, werden dort verdichtet und durch Rohr 5 in die Heizkammer 6 des Apparates 1 geführt. In Leitung 2 wird durch Düse 7 Base in die Br den gespritzt.



  Die Base wird clurch das Rohr 8 zugeführt, das in die Dampfleitung 9 mündet, durch die   DampfzusatzvoneinerStufe    des Kompressors nach der Düse   geleitet wird. Dampf-    zusatz und Base kommen in der D se 7, welche in der Zeichnung beispielsweise das Mischorgan bildet, zur Mischung.



  



  Process for preventing corrosion.



   The main patent describes a method for preventing corrosion, according to which acidic vapors and gases are made at least chemically neutral after exiting the liquid by mixing with a base.



   The effectiveness of this neutralization depends on the intimate mixture of the base with the vapors or gases. Since it is mostly a matter of very small quantities of base that have to be introduced, it can be difficult to achieve good distribution in the vapors or gases. To facilitate this distribution, according to? In the present invention, the base is mixed with additional steam which, due to its larger volume, causes the base to be distributed, possibly with atomization of the same.



  This additional steam can be introduced into a device for introducing the base. In the presence of a vapor compressor according to FIG. 4 of the main patent, this additional steam is advantageously taken from the first stage a-uf the suction side, i.e. between line 30 and 33. If the pressure is not sufficient, steam can be obtained from an arbitrarily higher one Remove the compressor stage. The additional steam is not lost in this combination, but rather describes a cycle through the compressor.



   In the accompanying drawing, for example, the present method is shown schematically with the use of steam additive from a stage of a vapor compressor. The gases go from apparatus 1 through pipe 2 and mixing apparatus 3 into vapor compressor 4, where they are compressed and passed through pipe 5 into heating chamber 6 of apparatus 1. In line 2, base is injected into the Br through nozzle 7.



  The base is fed in through the pipe 8 which opens into the steam line 9 through which the steam addition is directed from a stage of the compressor after the nozzle. The addition of steam and base are mixed in the nozzle 7, which in the drawing, for example, forms the mixing element.
