Description
Verfahren zum Trennen von Gas- und Dampfgemischeu durch Absorption mittels ahtiver Kohle. Durch Absorption von Gas- und Dampf gemischen bzw. Teilen solcher mittels poröser (aktiver) Kohle kann man eine Trennung der Gemische in ihre Einzelbestandteile oder in Mischungen bestimmter Einzelbestandteile herbeiführen. Man kann beispielsweise entweder einen Teil des Gemisches der Kohle unabsorbiert passieren lassen, oder man kann das gesamte Gasgemisch auf eine lange Kohlestrecke aufladen, auf welcher sich die Einzelbestandteile in der Reihenfolge ihrer Ab- sorptionsfähigkeit verteilen, und kann dann bestimmte Teile der Absorptionsgtrecke ausschalten und den in ihnen absorbierten Teil durch Austreiben, Lösen oder sonstige Mittel wieder freimachen.Process for separating gas and vapor mixtures by absorption using active charcoal. By absorbing gas and vapor mixtures or parts of such by means of porous (active) charcoal, it is possible to separate the mixtures into their individual components or into mixtures of certain individual components. One can for example, either let pass a portion of the mixture of charcoal unabsorbed, or one can charge all of the gas mixture to a long carbon track, on which the individual components sorption spread in order of their waste and may then certain parts of the Absorptionsgtrecke off and the free the part absorbed in them by expelling, dissolving or other means.
Bei den eben beschriebenen Verfahren sird in jedem Falle zur ErreichLmg einer sicheren-und für eine gewisse Zeitdauer ausreichenden Wirkung und um nicht allzu häufig Kohleteile ausschalten zu müssen, große bis sehr ausgedehnte Schichten von Kohle notwendig, durch welche das Gemisch passieren muß, wobei es dann naturgemäß auch verhällnismäßig große Widerstände zu überwinden gilt.In the case of the methods just described, it is possible to achieve this in any case a safe effect and sufficient for a certain period of time and in order not to having to turn off coal too often, large to very extensive layers of coal necessary, through which the mixture must pass, whereby it then naturally there is also relatively great resistance to overcome.
Es wurde nun gefunden, daß man die Trennung in sehr viel vorteilhafterer Weise vornehmen kann, wenn man an Stelle einer dicken Kohleschicht eine dünnere Kohleschicht wählt, welche quer durch den Strom des Gemisches hindurchbewegt bzw. an welcher der zu trennende Strom vorbeigeführt wird. Hierbei wird es in der Regel vorteilhaft sein, die Kohleschicht endlos zu gestalten und sie bei ihrem Weitergang bis zur Wiederztiführung zu dem Strom des Gemisches bzw, nach Weitergang dieses Stromes zu entladen, was in beliebiger Weise erfolgen kann, sowie sie erforderlichenfalls wieder zu kühlen oder be- liebiger sonstiger Behandlung züi unterwerfen, um so den höchsten Grad dür Aufnahmefähigkuit wieder herbeizuführen. Durch Regelung des Vei#hältnisses der Schnelligkeit der Bewegung der Kohleschicht bzw. der Richtungsveränderung des Durebtritts des Gasdampfstromes zur Schnelligkeit des Durchtritts des Gasgemisches hat man es in der Hand, auf die Kohle entweder nur den am leichtesten absorbierbaren Teil des Gemisches aufzuladen oder außerdem noch den näch#,t leichteren usw.It has now been found that the separation can be carried out in a much more advantageous manner if, instead of a thick layer of carbon, a thinner layer of carbon is chosen, which is moved across the flow of the mixture or on which the flow to be separated is passed. In this case, it will usually be advantageous to make the carbon layer endless and to discharge it as it continues until it is returned to the flow of the mixture or after this flow has continued, which can be done in any way, and if necessary to cool it again or Working liebiger other treatment züi submit to bring about the highest level so Dür Aufnahmefähigkuit again. By regulating the ratio of the speed of the movement of the coal layer or the change in direction of the passage of the gas vapor flow to the speed of the passage of the gas mixture, one has the option of loading only the most easily absorbable part of the mixture onto the coal or also that part next #, t lighter etc.
Man kann auch mehrere derartig kontinuierlich arbeitende Absorptionsbänder hintereinanderschalten, entweder indem man die einzelnen Bärtelcr konzentrisch ineinanderschachtelt, oder indem man die Bänder unabhängig voneineiliander nacheinander folgen läßt. Man ist so in der, Lage, durch Regelung der Geschwindigkeit der einzelnen Ab sorptionsbäpder entsprechend den Absorptionsverhältnissen die einzelnen Bestandteile des Gemisches in beliebiger Weise und mit der größten Schärfe voneinander zu trennen. Von den einzelnen Bändern lassen sich dann die Einzelbestandteile des Gemisches kontinuierlich in beliebiger Weise isoliert gewinnen.It is also possible to connect several such continuously working absorption bands one behind the other, either by nesting the individual Bärtelcr concentrically one inside the other, or by letting the bands follow one another independently of one another. It is to be separated as in the, position, by regulating the speed of the individual From sorptionsbäpder corresponding to the absorption conditions, the individual components of the mixture in any desired way and with the highest sharpness from each other. The individual components of the mixture can then be isolated continuously in any desired manner from the individual strips.
Eine Trennung der Bestandteile eines Gemisches kann mittels des kontinuierlichen Bandes auch dadurch erfolgen, daß man zunächst auf ein Band oder je ein Band eine Mischung mehrerer Bestandteile des Gemisches auflädt und beim Abblasen mittels Wasserdampfs oder Gase unter Nutzbarmachung des Umstandes, daß hierbei die Einzelbestandteile in der umgekehrten Reihenfolge ihrer Absorptionsfähigkeit ausgetrieben werden, die einzelnen Fraktionen getrennt auffängt, entweder indem man vollständig getrennte Ströme des Austreibemittels durch das Band hindurchführt, - oder indem man einen Strom einführt und diesen an der Austrittstelle in mehrere Teile unterteilt.The constituents of a mixture can also be separated by means of the continuous belt by first loading a mixture of several constituents of the mixture onto a belt or one belt each and, when blowing off with steam or gases, making use of the fact that the individual constituents are in the In the reverse order of their absorbency, the individual fractions are collected separately, either by passing completely separate streams of the expelling agent through the belt, or by introducing a stream and dividing it into several parts at the exit point.
Nach dem neuen Verfahren gelingt es unter Vermeidung großer Widerstände und mii sehr geringer Kohlenmenge kontinuierlich und unter Ausnutzung der immer wiederhergestellten höchsten Reaktionsfähigkeit der Kohle, also mit vollgesteigertern Wirkungsgrad, die Gemische von Gasen und Dämpfen zu zerlegen. Von besbnderer Wichtigkeit ist auch der sehr geringe Raumbedarf, der zur Ausführung des Verfahrens erforderlich ist. Außerdem ist der Verbrauch des Ablademittels, wie beispielsweise Dampf, infolge der. nur dünnen Kohleschicht außerordentlich gering.The new process succeeds in avoiding great resistance and with a very small amount of coal continuously and always taking advantage of it restored highest reactivity of coal, so with fully increased Efficiency to break down the mixtures of gases and vapors. Of more importance is also the very small space required to carry out the process is. In addition, the consumption of the unloading means such as steam is due the. only a thin layer of carbon extremely small.
