Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei Benutzung von Wässern, die beim Einkochen im Dampfkessel, aber auch bei gewöhnlicher Temperatur und Druck Sauerstoff in Gasform entwickeln, tritt leicht eine Korrosion des Eisens ein. Diese Korrosion kann man verhindern, wenn man den Sauerstoff des Wassers entfernt.When using water that is boiled down in a steam boiler, but also with normal If temperature and pressure develop oxygen in gaseous form, corrosion easily occurs of iron. This corrosion can be prevented by using the oxygen of the water away.

Die Entfernung des Sauerstoffs kann man nun dadurch erreichen, daß man dem WasserThe removal of the oxygen can now be achieved by adding to the water

ίο schweflige Säure oder hydroschweflige Säure oder eine der Polythionsäuren (Di-, Tri-, Tetraoder Pentathionsäure) oder Schwefelwasserstoff, also kurz alle reduzierenden Schwefelverbindungen oder deren Salze in der theoretischen,ίο sulphurous acid or hydrosulphurous acid or one of the polythionic acids (di-, tri-, tetra or pentathionic acid) or hydrogen sulfide, So in short all reducing sulfur compounds or their salts in the theoretical,

!5 in der ungenügenden oder in der überschüssigen Menge hinzufügt. Die leichtere Aufnahme des Sauerstoffs durch diese Schwefelverbindungen, wobei diese eine Oxydation erfahren, kann man durch Zusatz von geringen Mengen aller katalytisch wirkenden Stoffe, wie z. B. Eisen-, Kupfersalze usw., noch erheblich beschleunigen. ! 5 in the insufficient or in the excess Add amount. The easier absorption of oxygen by these sulfur compounds, These can be oxidized by adding small amounts all catalytically active substances, such as. B. iron, copper salts, etc., still accelerate considerably.

So z. B. setzt man einem Wasser, das 7 g Sauerstoff in icbm enthält, etwa 46 g NaHSO3 oder etwa 56 g Na2 S O3 hinzu. Geringe Menge z. B. eines Kupfersalzes erleichtert die Aufnahme des Sauerstoffs erheblich. Oder man setzt obigem Wasser z. B. 20 g Na2 S oder andere Sulfide z. B. der Schwermetalle oder Sulfhydrate oder Polysulfide oder freien Schwefelwasserstoff in entsprechender Menge mit oder ohne Zufügung eines Katalysators hinzu.So z. B. one adds about 46 g of NaHSO 3 or about 56 g of Na 2 SO 3 to water that contains 7 g of oxygen in icbm. Small amount z. B. a copper salt facilitates the absorption of oxygen considerably. Or you put the above water z. B. 20 g Na 2 S or other sulfides z. B. the heavy metals or sulfhydrates or polysulfides or free hydrogen sulfide in the appropriate amount with or without the addition of a catalyst.
