Description

Verfahren zur Geruchsverbesserung von Benzin Die Behandlung von Benzinen mit Natronlauge zur Entfernung unerwünschter Bestandteile ist ein viel angewandtes Verfahren in der erdölverarbeitenden Industrie. Man kann eine ähnliche, in manchen Fällen günstigere Verbesserung von Benzinen erreichen, indem man dieselben über mit Natronlauge getränkte aktive Kohle leitet.Process for improving the smell of gasoline The treatment of gasoline Using caustic soda to remove unwanted components is a widely used one Process in the petroleum processing industry. One can have a similar one, in some Cases achieve better improvement from gasolines by using the same over Active charcoal soaked in caustic soda conducts.

Es wurde nun gefunden, daß man vorteilhaft die Behandlung mit Lauge und A-Kohle in zwei Stufen durchführt, dergestalt, daß man in der ersten Stufe die Lösung der in Benzin enthaltenen schwefelhaltigen Verbindungen, insbesondere der Merkaptarne, in Natronlauge vornimmt und in der zweiten Stufe die auf solche Weise mit schwefelhaltigen Produkten beladene Natronlauge durch Berührung mit A-Kohle oder anderen Adsorbentien in einen für die Neuaufnahme schwefelhaltiger Produkte verwendbaren Ausgangszustand bringt. Das Verfahren arbeitet in folgender Weise: Das zu reinigende Benzin wird in einem Waschturm mit Natronlauge im Gegenstromprinzip gewaschen. Das Benzin tritt von unten in den Waschturm ein und wird dort durch geeignete apparative Maßnahmen fein verteilt, während die Natronlauge von oben eingebracht wird. Die am Boden des Waschturmes abgezogene Lauge wird in einem zweiten Waschturm, der mit A-Kohle gefüllt ist, von den in der Lauge angereicherten Merkaptanen befreit und dann wieder in den anderen Waschturm gedrückt, um dort weiteres Benzin zu raffinieren.It has now been found that treatment with alkali is advantageous and charcoal carries out in two stages, in such a way that in the first stage the Solution of the sulfur-containing compounds contained in gasoline, especially the Merkaptarne, made in caustic soda and in the second stage the in such a way Caustic soda loaded with sulphurous products from contact with charcoal or other adsorbents in one for the new absorption of sulfur-containing products brings usable initial state. The procedure works in the following way: The gasoline to be cleaned is in a washing tower with caustic soda using the countercurrent principle washed. The gasoline enters the washing tower from below and is there through suitable apparatus measures finely distributed, while the sodium hydroxide solution is introduced from above will. The lye drawn off at the bottom of the washing tower is transferred to a second washing tower, which is filled with activated charcoal, freed from the mercaptans enriched in the lye and then pushed back into the other washing tower to refine more gasoline there.

Dieser Kreislauf der Lauge, der sich hinsichtlich Umlaufgeschwindigkeit und hinsichtlich des Verhältnissec Lauge zu Kohle variieren läßt, sowie der variable Benzindurchsatz ermöglichen einen Einwirkungsgrad der Lauge auf das Benzin je nach dessen Gehalt an unerwünschten Bestandteilen, somit Einstellung optimaler Bedingungen. Das Verfahren ermöglicht auch eine Anpassung bezüglich des unterschiedlichen Gehaltes des behandelten Benzins an den verschiedenen Arten von Merkaptanen.This cycle of the lye, which is related to the speed of rotation and can vary with regard to the ratio of lye to coal, as well as the variable Petrol throughput allow the alkali to have an impact on the petrol depending on its content of undesirable components, thus setting optimal conditions. The method also enables an adaptation with regard to the different content of the treated gasoline in the different types of Mercaptans.
