Abstract
Description
Verfahren und Vorrichtung zur Trocknung und Reinigung von Luft und anderen Gasen durch AdsorPtionsmittel Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Trocknung und Reinigung von Luft und anderen Gasen von Kohlenwasserstoffen, Kohlensäure und Aromaten mittels Kleselsäuregel, Molsieberl und anderen bekannten Adsorptionsmitteln sowie die Regenerierung der Adsorptionsmittel durch Zuführung von Wärme.Method and device for drying and purifying air and other gases by adsorbent The invention relates to a method and a Device for drying and cleaning air and other gases from hydrocarbons, Carbon dioxide and aromatics using silica gel, Molsieberl and other known ones Adsorbents as well as the regeneration of the adsorbents by feeding of warmth.
Es ist bekannt, daß die Lufttrocknung zur Erzielung eines Taupunktes bis zu ca. - 50 0Celsius mittels Kieselsäureelen in zwei Adsorbern wechselweise durchgeführt wird. Dabei wird der eine Adsorber beladen, während der andere durch Fuführung von Wärme desorbiert wird. Die Desorption des Gels wird hierbei unter Zuführung von ca. 150°Celsius erwärmten Dosorptionsgases durchgeführt. Besonders bei Luftzerlegungs anlagen ist es notwendig eine intensive Trocknung durchzufahren, um die Voraussetzungen fär einen Dauerbetrieb zu schaffen. Bei Gastrocknungsanlagen ist weiterhin bekannt, daß eine stufenweise Trocziung durch Auf teilung in einzelne Adsorrtionsschichten erfolgt. Dies kann auch mittels Zwischenkühlung der Luft erfolgen, was jedoch einen erheblichen apparatetechnischen flehrauBwand bedeutet.It is known that air drying is used to achieve a dew point up to approx. - 50 ° C by means of silica gel in two adsorbers alternately is carried out. One adsorber is loaded while the other is loaded Supply of heat is desorbed. The desorption of the gel is hereby under Feeding of approx. 150 ° Celsius heated dosing gas carried out. Particularly In the case of air separation plants, it is necessary to carry out intensive drying, to create the conditions for continuous operation. With gas drying systems is also known that a gradual Trocziung by dividing up into individual Adsorption layers takes place. This can also be done by means of intermediate cooling of the air, However, this means a considerable amount of equipment required.
Es ist-weiterhin die Anordnung von stufenweise hintereinander geschalteten Gelarten bekannt geworden.It is still the arrangement of one after the other Gelarten became known.
weitere Adsorptionsmitte:l zur Trocknung von Gasen und zur Erzielung eines Taupunktes bis ca. - 50 0Celsius sind Molekularsiebe, die neben der Adsorption von Wasserdampf in der Lage sind, z. B. Kohlensäure, Kohlenwasserstoffe und Äromaten zu adsorbieren.further adsorption agents: l for drying gases and for achieving of a dew point up to approx. - 50 0Celsius are molecular sieves, which in addition to the adsorption of water vapor are able to, for. B. carbonic acid, hydrocarbons and aromatics to adsorb.
Diese Adsorber werden ebenfalls wechselweise betrieben, um eine kontinuierliche Lufttrocknung und Reinigung z. B. bei Luftzerlegungsanlagen zu gewährleisten.These adsorbers are also operated alternately to ensure a continuous Air drying and cleaning e.g. B. to ensure air separation plants.
Molsiebe erfordern zur Regenerierung wesentlich höhere Aktivierungstemperaturen als Gele.Molecular sieves require significantly higher activation temperatures for regeneration as gels.
Um die Wärmeabstrahlung beim Regenerieren zu vermindern, werden die Adsorber mit einer Isolationsschicht umgeben oder doppelwandig ausgeführt. Isolationen vrirlLen einem schnellen Wiedereinsatz der Adsorber infolge verlngerter Abkühldauer entgegen. Außerdem steigen die Fertigungskosten.In order to reduce the heat radiation during regeneration, the The adsorber is surrounded by an insulating layer or has a double-walled design. Isolations prevent the adsorber from being used again quickly as a result of the extended cooling time opposite. In addition, the manufacturing cost increases.
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren und eine Vorrichtung zur adsorptiven Reinigung von Luft und Gasen zu gestalten, welche eine olJtimale Iufttrocknung und eine ökonomische Gasreinitgung und Regenerierung g.ewährleisten und den nergieaufwand der Refrenerierung durch die Anordnung der Adsorptionsmittel wesentlich senken.The invention is based on the object, a method and a To design a device for the adsorptive cleaning of air and gases, which a Ensure optimal air drying and economical gas cleaning and regeneration and the energy consumption of the regeneration due to the arrangement of the adsorbents significantly lower.
Erfindungsgemäß wird dies dadurch erreicht, daß das Verfahren zur Reinigung und Trocknung von Luft und Gasen mittels bekannten Adsorptionsmitteln wie Kieselsäukregel, I~olsieben und anderen Adsorptionsmitteln durchgeführt wird, und daß die Re-generierung der Adsorptionsmittel durch Wärmezuführung erfolgt, indem das zu trocknende und zu reinigende Gas zuerst einem adsorptiven Troclinungsmittel und danach -dem adir sorptiven Reinigu;tigsmittel zugeführt wird, wobei das Trocknungsmittel gleichzeitig als Isolationsmaterial des Adsorbers zur Verminderung von Wärmeverlusten während des Desorptionsprozesses dient, und daß das Gas bzw. die Luft zuerst durch die äußeren ringförmig angeordneten Adsorptionsmittel wie Z. B. Kieselsäuregel geleitet ird und danach den innen angeordneten Reinigungsmittelschichten, die z.B. aus Molsieben bestehen, zugeleitet wird, und daß die ringförmig angeordneten Adsorptionsmittel als Isolationsmantel verwender werden, und daß die den ringförmigen Querschnitt bildenden Wände zur Verminderung der flandgängigkeit mit Schikanen versehen sind, und daß das aufgeheizte Desorptionsgas zuerst dem Reinigungsmittel und danach dem Trocknungsmittel zugeführt wird, und daß hierbei die Reinigungsschichten durch die äußere Trocknungsschicht gegen Wärmeabstrahlung isoliert sind.According to the invention this is achieved in that the method for Purification and drying of air and gases using known adsorbents how silica rule, oil sieves and other adsorbents are carried out, and that the adsorbent is regenerated by supplying heat by the gas to be dried and cleaned first to an adsorptive drying agent and then -dem adir sorptive cleaning agent is supplied, wherein the drying agent at the same time as the insulation material of the adsorber to reduce heat losses serves during the desorption process, and that the gas or air passes through first the outer ring-shaped adsorbents such as silica gel ird and then the inside arranged cleaning agent layers, e.g. made of molecular sieves exist, is fed, and that the annularly arranged adsorbent be used as an insulating jacket, and that the annular cross-section forming walls are provided with baffles to reduce the ability to navigate the land, and that the heated desorption gas first the detergent and then fed to the drying agent, and that in this case the cleaning layers are insulated against heat radiation by the outer drying layer.
