Description
Verfahren und Vorrichtung zur Trennung von Gasgemischen mittels periodisch
umgeschalteter Adsorber
Erhndtingsgetnäß ist eilte Verknüpfung des Verfahrensschrittes der Entladung eitles Adsorbers durch Frischgas finit demjenigen der unmittelbar anschließenden Beladung des anderen Adsorbers durch das itn ersten Adsorberteil angereicherte Frischgas heabsichtigt. 1)1e ausgetriebenen Bestandteile können unter Uniständen nach einer Reihe voll U nischaltun-en zwischen den Adsorbern als Kondensat altgeschieden und abgeführt Nverden. Die mit (lein Konzentrat abgeführte Adsorbatinenge entspricht ini Heharrungszustand der mit dein Frischgas nett zugeführten. Statt eilte Abscheidung von Kondensaten vorztineliritett, genügt es auch, nach eitler Reibe von LTinschaltungen zwischen den A(I-sorbern einen Teil des finit Desorbat angereicherten Frischgases zu entnehmen und einer weiteren Atireicherungsstufe zuzuführen. Die Entnahme kann je nach I# lüclitigkeit der angereicherten Bestandteile all verschiedenen Stellen der gespülten Adalso all wärmerer oder kälterer Stelle, erfolgen.Erhndtingsgetnäß is hasty linking of the process step Discharge of vain adsorber through fresh gas finite that of the immediately following Loading of the other adsorber by fresh gas enriched in the first adsorber part he intends. 1) 1e expelled constituents can under university stands after a Row of full U nischaltun-en between the adsorbers separated as condensate and taken away from Nverden. The amount of adsorbate discharged with a concentrate corresponds to ini steady state of the nicely supplied with your fresh gas. Instead of hurried separation of condensates vorztineliritett, it is also sufficient, after vain rub of LTin connections between the A (I-sorbers a part of the finite desorbate enriched fresh gas to be taken and fed to a further atire assurance level. The removal can depending on the volatility of the enriched constituents in all different places the rinsed Adalso in any warmer or colder place.
Nach einem weiteren 1:rtin(lungsgedanken kamt zur Rückget\ inneng der vom leas mitgeführten Wärme auf ((ei- Seite des Frischgaseintritts in den Adsorber ltzt\. des Restgasaustritts aus (lern anderen Adsorbe-i- noch je ein alt sich bekannter \V:it-mespeicher vorgesehen werden, wodurch sich die W:irineverluste auf ein Minimum verringern.After another 1: rtin (lungs thought came to the return the heat carried along by the leas on ((one side of the fresh gas inlet into the adsorber lately \. the residual gas outlet from (learn other adsorbe-i- still an old familiar \ V: it-mespeicher are provided, whereby the W: irine losses to a minimum to decrease.
Heizung und Kühlung kann erfindungsgemäß dauernd unter diesen Umständen betrieben werden. Nach einem weiteren Erhndutigsgedanken können auch die aufgewendeten Kältebeträge in rationellster «"eise ausgenutzt und Kälteverluste vermieden werden, wenn inan die Adsorbensmassen gleichzeitig zur Gasanreicherung und zur Speicherung von Wärme bzw. l11-älte verwendet. In diesem Fall arbeitcn die genannten l@fassett nach bekannter Speicherart int Temperaturgefälle, cl. 1i. also, daß das mit heißem Frischgas gespülte und dabei zunehmend erwärmte Adsorbens nicht ganz durchgeheizt und ((aß das finit altgekühltem Frischgas beaufschlagte und -zunehmend gekühlte Adsorbens nicht ganz durchgekühlt so (laß beide Speicher auch vor ihrer l'ntschalttin<@ noch ein wesentliches Tetnperaturgefälle aufweisen. Die Adsorbensmassen arbeiten also sowohl als Wärmespeicher als auch als Kältespeicher, wenn sie in der beschriebenen Weise betrieben werden.According to the invention, heating and cooling can be permanent under these circumstances operate. After a further thought, the expended Cooling amounts are used in the most efficient way and cooling losses are avoided, if inan the adsorbent masses for gas enrichment and storage at the same time used by heat and / or cold. In this case, the above-mentioned facets work according to known storage type int temperature gradient, cl. 1i. So that with hot Fresh gas flushed and increasingly heated adsorbent not fully heated and ((ate the finitely old-cooled fresh gas admitted and increasingly cooled Adsorbent not completely cooled so (leave both storage tanks also before they are switched on <@ still show a substantial temperature gradient. The adsorbent masses work so both as a heat store and as a cold store, if they are described in the Wise operated.
Zweckmäßig ist es, (laß zwischen Kühlvorrichtung und gespültem Adsorbens nach der letzten Phase der Spülung, also kurz v(»- der 1-inschaltung, eine solche Temperaturdifferenz zwischen Adsorbensendschicht und Kühlvorrichtung und eine so tiefe Temperatur der Kühlung eingestellt ist, daß nach Unischaltung des Gasstroms der Kältevorrat des tiefgekühlten angereicherten I#rischgases ausreicht, uni die Adsorption der von ihin mitgeführten angereicherten bzw. nach der Kondensation noch verbliebenen Gasbestandteile zu gewährleisten. Hierbei ist zu beachten, daß der Kiiltevorrat ausreichen muß, uni das .ldsorl)eiis genügend herunterzukühlen sowie die Adsorptionswärine der zu adsorbierenden Gasbestandteile zu decken. Ist daher mehr Gas zu adsorbieren, ist der Teinperattirsprung zwischen Kühlung und Adsorbens größer eitlzustellen. Andererseits inuß (las Teinperaturniveatt der Kühleinrichtung so tief eingestellt werden, daß die =Aufnahmefähigkeit der verwendeten Adsorbensmenge für die Bindung sämtlicher noch ini Gas verbliebenen angereicherten Gasbestandteile ausreicht.It is useful to (leave between the cooling device and the rinsed adsorbent after the last phase of flushing, i.e. briefly v (»- the 1 connection, such a Temperature difference between the adsorbent end layer and cooling device and a so low temperature of the cooling is set that after disconnection of the gas flow the cold supply of the deep-frozen, enriched irish gas is sufficient, uni the Adsorption of the enriched ones carried along by ihin or still after the condensation to ensure remaining gas components. It should be noted that the There must be sufficient coolant supply to cool down the .ldsorl) ice sufficiently as well as to cover the adsorption heat of the gas components to be adsorbed. Is therefore To adsorb more gas is the step between cooling and adsorbent greater vanity. On the other hand, the temperature level of the cooling device must be read be set so low that the = absorption capacity of the amount of adsorbent used for the binding of all enriched gas components still remaining in the gas sufficient.
Man kann die Erfindung derart ausführen, daß nian die Adsorbensschichten in nebeneinanderstehenden Adsorbern mit senkrecht stehender L:ingsachse vors vorerhitzten bzlv. voni tiefgekühlten Frischgas durchströmen läßt.The invention can be carried out in such a way that the adsorbent layers are nian preheated in adjoining adsorbers with a vertical longitudinal axis bzlv. allows frozen fresh gas to flow through.
Iin gespülten Adsorber wird dabei unter bestimmten Umständen besonders bei lüiheren Adsorbatkonzentrationen in den rückwärtigen noch kälteren Teilen des Adsorbens eilte vorübergehende Kondensation der ausgetriebenen llestandteile eintreten. Gleichzeitig wird dabei eitle gewisse @eiinischung der Kondensate stattfinden und eine gewisse Kondensatmenge vom Adsorbetls aufgesogen, wenn das Kondensat über gr<ißere Schichtlängen des Adsorbens abiv:irts wandern niuli, die 111,11) unter Umständen vermeiden will. U.s wird eialter das etwa anfallende Kondensat am Entstehungsort gesammelt und abgeführt. Das kann z. li. niit Hilfe von Altlenk-und Saiitinelblechen oder "hassen geschehen oder durch waagerechte oder schräge Anordnung der Adsorbensschichten, wobei die anfallenden Kondensate in der Nähe ihres Entstehungsc»-ts, z. 13. all der Unterseite der geneigten Behälter, gesammelt und abgeführt Nverden können. ('in (las Ablaufen der Kondensate zu beschleunigen und zu erleichtern, kann es zweckmäßig sein, in geeigiieteii Abständen, also dort, wo die Kondensate anfallen, die Adsorbensschicht zu unterbrechen litt(] eitle kurze Schicht aus Speichermassen mit in(*igliclist glatter Oberfläche einzuschalten, die nicht nur miiglichst wenig Kondensat aufsaugt, sondern auch niögliclist schnell abführt und damit der Ein« irkung des all diesen Stelle während des Spülvorgangs zunehmend wärmer werdenden Gases entzieht. bevor die Kondensate wieder verdunsten.In a purged adsorber, under certain circumstances, this becomes particularly important with lüiheren adsorbate concentrations in the rear even colder parts of the Adsorbent rushed to enter temporary condensation of the expelled oil components. At the same time, a certain amount of mixing of the condensates will take place and a certain amount of condensate is absorbed by the adsorbent if the condensate is larger than that Layer lengths of the adsorbent abiv: irts migrate niuli, the 111,11) under certain circumstances want to avoid. The condensate that may accumulate at the point of origin will age collected and discharged. This can e.g. left with the help of old steering and saiitinel plates or "hate happened or by horizontal or inclined arrangement of the adsorbent layers, whereby the resulting condensates in the vicinity of their origin, z. 13. all the underside of the inclined container, collected and discharged Nverden can. ('in (It can be useful to accelerate and facilitate the drainage of the condensates be at geeigiieteii intervals, i.e. where the condensates occur, the adsorbent layer to interrupt suffered (] vain short layer of storage masses with in (* igliclist to switch on a smooth surface that not only absorbs as little condensate as possible, but also niögliclist quickly leads away and with it the effect of all these Location withdraws increasingly warmer gas during the flushing process. before the condensates evaporate again.
