Abstract

The invention relates to a process and an apparatus for the adsorption or chemisorption of gaseous substances from an untreated gas stream as an addition to DE-C ... (P 3801913.2). As an addition to the main patent, moisture, preferably steam, is added to the untreated gas and/or the adsorbent and/or the mixture of both substances.

Description

Die Erfindung betrifft ein Verfahren zur Adsorption bzw. Chemiesorption von gasförmigen Stoffen aus einem Rohrgasstrom als Zusatzpatent nach Anspruch 1 des DE-PS . . . (P 38 01 913.2).The invention relates to a method for adsorption or chemisorption of gaseous substances from a pipe gas stream as an additional patent according to claim 1 of DE-PS. . . (P 38 01 913.2).

Im Oberbegriff des Hauptanspruches des Hauptpatents werden Eigenschaften der Adsorbentien erwähnt, die eine chemische Reaktion bewirken. Dies kann z. B. Feuchtigkeit sein, wenn nämlich die Gegenwart von Wasser für eine chemische Reaktion erforderlich ist.Properties are in the preamble of the main claim of the main patent of adsorbents mentioned that cause a chemical reaction. This can e.g. B. moisture, namely if the present of water is required for a chemical reaction.

In Weiterentwicklung des Hauptpatents wird deshalb vorgeschlagen, daß das Rohgas und/oder das Adsorbens und/oder Gemisch aus Rohgas und Adsorbens mit Feuchtigkeit beaufschlagt wird, wobei die Temperaturen derart eingestellt sind, daß der Taupunkt im Gas nicht unterschritten wird. Dabei kann das Frischadsorbens in feinstvermahlener Form dem Gasstrom zugegeben werden. Als Feuchtigkeit kann Wasser, eine entsprechende Lösung oder Dampf verwendet werden. Je nach Verfahrensablauf kann die Feuchtigkeit und/oder der Dampf in den Rohgasstrom in das Frischadsorbens oder in den rezirkulierenden Gasstrom eingegeben werden. Auch ist denkbar, die Feuchtigkeit während der Feinstvermahlung dem Adsorbens zuzugeben.In further development of the main patent, it is therefore proposed that the raw gas and / or the adsorbent and / or mixture Raw gas and adsorbent is subjected to moisture, the Temperatures are set so that the dew point in the gas is not undercut. The fresh adsorbent can finely ground form can be added to the gas stream. As moisture can use water, a suitable solution or steam will. Depending on the procedure, the moisture and / or the steam in the raw gas stream in the fresh adsorbent or in the recirculating gas flow can be entered. It is also conceivable to add the moisture to the adsorbent during the fine grinding.

Die Zeichnung zeigt einen Querschnitt durch den erfindungsgemäßen Gegenstand, wobei die angeführten Positionszahlen dem Hauptpatent entsprechen. The drawing shows a cross section through the invention Subject, the item numbers listed the main patent correspond.  

Hinzugefügt sind die Mühle 30 innerhalb der Adsorbensleitung 19, mit der Zufuhrleitung 19 a für das Frischadsorbens. Die Dampfzufuhrleitungen sind mit 31 beziffert, wobei die Leitung 31 a in die Mühle 30, die Leitung 31 b in die Adsorbensleitung 19, die Leitung 31 c in den Filterraum unterhalb der Filterschläuche 8 und die Leitung 31 d in die Rohgasleitung eingeführt sind.The mill 30 is added within the adsorbent line 19 , with the feed line 19 a for the fresh adsorbent. The steam supply lines are numbered 31 , line 31 a being introduced into the mill 30 , line 31 b into the adsorbent line 19 , line 31 c into the filter space below the filter bags 8 and line 31 d into the raw gas line.
