Description

Verfahren zum Auswaschen von Benzol aus Kokereigasen o. dgl. mittels Paraffinöls In neuerer Zeit ist zum Auswaschen des Benzols aus Kokereigasen o. dgl. an Stelle des aus dem Steinkohlenteer stammenden Waschöles Paraffinöl vorgeschlagen worden, das unter anderen aus Braunkohlenteer gewonnen werden kann. Die anfängliche Waschwirkung des Paraffinöles ist größer als die des aus Steinkohlenteer gewonnenen Waschöles, doch zeigt das Paraffinöl die unangenehme Eigenschaft, im Laufe der Zeit an Waschwirkung einzubüßen und überdies in den Wäschern Verschmutzungen anzusetzen, die nur schwer zu entfernen sind.Method for washing benzene from coke oven gases o. The like. Means Paraffin oil In more recent times, benzene has been washed out of coke oven gases o. suggested instead of the washing oil derived from coal tar, paraffin oil which can be obtained from lignite tar, among other things. The initial one The washing effect of paraffin oil is greater than that of coal tar obtained Washing oil, however, the paraffin oil shows the unpleasant property over time to lose the washing effect and, moreover, to accumulate soiling in the washers, difficult to remove.

Tun zeigen sich allerdings auch bei dem aus Steinkohlenteer gewonnenen Waschöl ähnliche Erscheinungen; auch bei diesem läßt die Waschwirkung mit der Zeit nach, und die Wäscher zeigen Verschmutzungen. Diese Vorgänge sind mit einer Erhöhung des mittleren Molekulargewichtes des Steinkohlenteerwaschöles verbunden und werden auf verschiedene während des Waschprozesses unerwünschterweise aus dem Gase aufgenommene (absorbierte) Stoffe zurückgeführt. Als Mittel gegen die Waschölverdickungen sind die Anwendung niedriger Abtriebtemperaturen und eine Destillation im Vakuum bekannt.However, action can also be seen in the case of coal tar extracted Appearance similar to washing oil; Even with this, the washing effect decreases with time after, and the scrubbers show soiling. These operations are with an increase of the mean molecular weight of coal tar washing oil and are to various undesirably absorbed from the gases during the washing process (absorbed) substances returned. As a means against the washing oil thickening are the use of low stripping temperatures and distillation in vacuo are known.

Der Erfinder konnte feststellen, daß diese Mittel zur Verhütung der Verschmutzungen in den Wäschern bei den Paraffinölen ohne Erfolg blieben, er führte dieselben vielmehr darauf zurück, daß die im Gase enthaltenen Teerbestandteile von dem Paraffinöl angelagert (adsorbiert) werden, und schlägt gemäß der Erfindung als Mittel zur Verhütung der Wäscherverschmutzungen die mechanische Reinigung des Paraffinöles von den adsorbierten teerigen Verunreinigungen vor. Zu einer solchen mechanischen Reinigung können bekannte Einrichtungen, wie Ruhebehälter oder Filterpressen, Anwendung finden. Diese Reinigungseinrichtungen können in einen aus dem Hauptstrom des Paraffinöles abgezweigten Teilstrom oder Teilkreislauf eingeschaltet werden. Die Entfernung der Verunreinigungen kann aber auch intermittierend vorgenommen werden, so daß eine gewisse Menge Paraffinöl gereinigt und dann wieder in den Kreislauf zugegeben wirdThe inventor was able to determine that these means for the prevention of Soiling in the washers with the paraffin oils was unsuccessful, he led the same rather back to the fact that the tar components contained in the gas of the paraffin oil are attached (adsorbed), and proposes according to the invention as Means for preventing the laundry soiling the mechanical cleaning of the paraffin oil of the tarry contaminants adsorbed. To such a mechanical one Known devices, such as resting tanks or filter presses, can be used for cleaning Find. These cleaning devices can be integrated into one of the main flow of paraffin oil branched off partial flow or partial circuit are switched on. The removal of the Impurities can also be made intermittently, so that a a certain amount of paraffin oil is cleaned and then added back into the circuit
