摘要： Die Erfindung betrifft ein Verfahren zur Rückgewinnung von Salzsäure aus konzentrierten Metallchloridlösungen, die einen hohen Eisenchloridanteil aufweisen, wobei das Eisen zumindest teilweise in dreiwertiger Form vorliegt. Diese Metallchloridlösungen fallen insbesondere bei der Säurelaugung von Erzen an.
Das erfindungsgemäße Verfahren umfasst die Schritte:
a) Sprühgranulation der Metallchloridlösung bei Temperaturen von 150 bis 300°C, bevorzugt 150 bis 250°C, wobei zumindest ein Teil des Eisenchlorids in Eisenoxid umgewandelt wird und ein Granulat sowie HCl-haltiges Gas entsteht, und HCl-haltiges Gas entsteht,
b) Pyrohydrolyse des in Verfahrensschritt a) entstandenen Granulats in einem Reaktor bei Temperaturen von über 550°C, bevorzugt über 800°C, wobei HCl-haltiges Gas entsteht,
c) Rückgewinnung überazeotroper Salzsäure (Konzentration >20 Gew.-%) aus den in den Verfahrensschritten a) und b) entstandenen HCl-haltigen Gasströmen.
Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass Lösungen mit hohem FeCl 3 -Gehalt verarbeitet werden können und dass ein Großteil der Wasserverdampfung bei niedrigen Temperaturen stattfindet und somit hohe Durchsätze in einer Anlage erreicht werden.

摘要： The present invention relates to a method for serial surface treatment of metallic components comprising aluminium surfaces, wherein an alkaline pretreatment is followed by a conversion treatment. According to the invention, the intention during the alkaline pretreatment is that a maximum value for the concentration of dissolved zinc is not exceeded, in order to ensure a sufficient quality of the corrosion-protective coating on the aluminium surface of the components following the surface treatment. In a preferred embodiment, the content of dissolved zinc is effectively held below the respective bath-typical maximum value of dissolved zinc by the addition of compounds constituting a source of sulphide ions. The functionality of the surface treatment can be additionally increased by likewise controlling the content of dissolved aluminium in the alkaline pretreatment such that, by adding compounds constituting a source for silicate anions, a threshold value for dissolved aluminium is not exceeded.

摘要： An embodiment of a method for recovering nitric acid from acid pickling solution includes introducing a treating material comprising at least one chemical into a pickling solution comprising free nitric acid. The treating material reacts with at least a portion of the free nitric acid in the pickling solution and produces NOx. A gas stream comprising at least a portion of the NOx is contacted with ozone, thereby forming oxidation products including nitrogen sesquioxide and nitrogen pentoxide. At least a portion of the nitrogen sesquioxide and nitrogen pentoxide is contacted with water, thereby forming nitric acid, and at least a portion of the nitric acid is collected.
