Zusatz zum Patente 186398 vom 13. Oktober 1906.Addendum to patent 186398 of October 13, 1906.
Patentiert im Deutschen Reiche vom 13. Januar 1911 ab. Längste Dauer: 12. Oktober 1921.Patented in the German Empire on January 13, 1911. Longest duration: October 12, 1921.
Bei der technischen Durchführung des im Hauptpatente geschützten Verfahrens, nach welchem die Darstellung von Salzsäuregas aus Kochsalz und Schwefelsäure in einem Medium von heißflüssigem Bisulfat erfolgt, hat sich gezeigt, daß die durch den Einlauf der Schwefelsäure in das heißflüssige Bisulfat erzeugten Strömungen das gleichmäßige Abfließen eines gut ausgearbeiteten Bisulfates erschweren. Sobald nämlich das aus der Retorte abfließende Bisulfat nicht genügend ausgearbeitet ist, treten in dem für den Abfluß des Bisulfates vorgesehenen, stark erhitzten Abflußrohre, welches nach oben gerichtet ist, Gasblasen auf, die den normalen Ablauf des geschmolzenen Salzes stören und durch ihren Gasdruck das geschmolzene Salz unregelmäßig, etwa in der Art einer Mammutpumpe nach außen befördern.During the technical implementation of the process protected in the main patent, according to which the representation of hydrochloric acid gas from table salt and sulfuric acid in one Medium of hot liquid bisulfate takes place, it has been shown that through the enema The currents of the sulfuric acid in the hot liquid bisulphate created the even drainage make a well-worked out bisulfate difficult. As soon as that from the retort outflowing bisulfate is not sufficiently worked out, occur in the for the drain the bisulphate provided, strongly heated drainage pipes, which are directed upwards, Gas bubbles that interfere with the normal flow of the molten salt and through their Gas pressure makes the molten salt irregular, somewhat like a mammoth pump convey outside.
Es wurde nun gefunden, daß man diese Störung am besten dadurch vermeidet, daß man die Umsetzung zwischen dem Kochsalz und der Schwefelsäure in die oberste Schicht des heißflüssigen Bisulfates oder noch besser auf die Oberfläche des flüssigen Bisulfates selbst verlegt.It has now been found that the best way to avoid this disturbance is that the reaction between the table salt and the sulfuric acid in the top layer of the hot liquid bisulfate or even better on the surface of the liquid bisulfate self-laid.
Es sinken dann die spezifisch leichten und noch stark sauren Schichten der Oberfläche, indem sich ihr spezifisches Gewicht langsam vergrößert, zu Boden und vereinigen sich mit den dort bereits befindlichen spezifisch sehr schweren Schichten von ausgearbeitetem heißen Bisulfat. Das Bisulfat fließt alsdann in langsamem, gleichmäßigem Strome von durchsichtiger, hellgelber Farbe ab und erstarrt beim Erkalten zu farblosem Bisulfat, das sich infolge seines geringen Eisengehaltes von dem gewöhnlichen Pfannensalze unterscheidet und sich vortrefflich zur Weiterverarbeitung auf Sulfat eignet.The specifically light and still strongly acidic layers of the surface then sink, as their specific gravity slowly increases, to the ground and unite with the specifically very heavy layers of elaborated hot already located there Bisulfate. The bisulfate then flows in a slow, steady stream of transparent, light yellow color and solidifies to colorless bisulphate when it cools, which, due to its low iron content, differs from the common pan salts and is excellent for further processing Sulphate is suitable.
Für die Durchführung des im Hauptpatente beschriebenen Verfahrens ist der gleichmäßige Ablauf des fertigen Bisulfates eine wesentliche Bedingung, da nur auf diese Weise eine Kontrolle des Prozesses, welcher eine scharfe Innehaltung des Beschickungsniveaus zur Voraussetzung hat, möglich ist. For the implementation of the process described in the main patent is the uniform Expiry of the finished bisulfate an essential condition, as only in this way one Control of the process, which requires a strict pause at the loading level, is possible.
