Abstract

Gas/liquid systems (G-L systems) in which biochemical reactions or other process engineering steps are carried out, tend to form foam on free surfaces. In most cases, this is an interference because the foam creates non-uniform operating conditions in the G-L system and takes up space in the equipment item concerned intended for its proper use. Hitherto, foam control has been carried out essentially by means of physical foam destroyers which effect a reduction in the equilibrium quantity of foam, or by means of chemical foaming preventers. The latter can prevent the formation of foam by addition of surface-active substances which, however, in most cases also cause undesired (bio-)chemical effects. These disadvantages are avoided if, according to the illustrative example shown, free surface can form in the entire equipment, which is completely filled by the G-L system, only at the highest point in the region of high shear forces and centrifugal forces, preferably in degassing cyclones. If gas escaping here inflates liquid lamellae, these are destroyed in statu nascendi by centrifugal forces and shear forces of the spinning flow and forced back into the rotating L phase. In this way, the formation of foam is physically suppressed without detrimental side effects.

Description

Verfahren und Vorrichtung zur Entgasung von Gas-Liquid-SystemenMethod and device for degassing gas-liquid systems

ohne Schaumbildung 1. Stand der Technik Viele (bio-)chemische Reaktionen und verfahrenstechnische Grundoperationen werden in Gas-Liquid-Systemen (G-L-Systemen) durchgeführt. Das Gas ist in der Regel in möglichst kleine Blasen zerteilt (dispergiert), um große G-L-Phasengrenzfläche für die Stoffübertragung zwischen G- und L-Phase zu schaffen. Dabei kann es sich um den Eintrag einer Gaskomponente (z.B. 02) von der G- in die L-Phase, um den Austrag einer Gaskomponente (z.B. without foam formation 1. State of the art Many (bio) chemical reactions and basic procedural operations are carried out in gas-liquid systems (G-L systems) carried out. The gas is usually divided (dispersed) into the smallest possible bubbles, around a large G-L phase interface for mass transfer between G and L phases to accomplish. This can involve the entry of a gas component (e.g. 02) from the G- to the L-phase in order to avoid the discharge of a gas component (e.g.

Co2) aus der L- in die G-Phase oder auch um den Übergang von Staubpartikeln aus der G- in die L-Phase (z.B. bei Gas-Naßwäschern) handeln /1/.Co2) from the L to the G phase or around the transition of dust particles act from the G to the L phase (e.g. with gas wet scrubbers) / 1 /.

Je nach Gehalt an grenzflächenaktiven Substanzen (Tensiden) bildet sich an freien Oberflächen der G-L-Systeme beim Gasaustritt Schaum. Das kann erwünscht sein, wenn z.B. suspendierte Partikel aus der L-Phase ausgetragen werden sollen nach dem Prinzip der Flotation /2/. In den meisten Fällen ist die Schaumbildung jedoch unerwünscht, oft sogar sehr nachteilig; denn im Schaum stellen sich völlig andere Bedingungen ein als im G-L-System. So kann z.B. bei Bioreaktoren unzureichende Substrat-Versorgung aerober Mikroorganismen in den Lamellen auftreten; oder bei Chemiereaktoren können suspendierte Reaktanden, Katalysatoren oder Adsorbentien im stagnierenden Schaum festgehalten werden. In jedem Fall bilden sich im Schaum andere Stoffverteilungen und es finden andere physikalisch-chemische Vorgänge statt als unter den im G-L-System eingestellten Betriebsbedingungen. Hinzu kommt, daß der von Schaum erfüllte Raum dem G-L-System und damit den gewollten verfahrenstechnischen Vorgängen entzogen wird.Forms depending on the content of surface-active substances (surfactants) foam builds up on free surfaces of the G-L systems when the gas escapes. That can be desirable if, for example, suspended particles are to be discharged from the L-phase according to the principle of flotation / 2 /. In most cases there is foaming however undesirable, often even very disadvantageous; because in the foam turn completely different conditions than in the G-L system. In the case of bioreactors, for example, insufficient Substrate supply of aerobic microorganisms occur in the lamellae; or at Chemical reactors can contain suspended reactants, catalysts or adsorbents be held in the stagnant foam. Either way, they form in the foam other distributions of substances and other physico-chemical processes take place than under the operating conditions set in the G-L system. In addition, that the foam-filled space corresponds to the G-L system and thus the desired process technology Operations is withdrawn.

Bisher erfolgte die Bekämpfung des Schaums entweder durch mechanische Schaumzerstörer, die aber Wellendurchführungen erfordern (Giftigkeit, Explosionsgefahr, Sterilität) oder durch Zusatz chemischer Antischaummittel, die sich aber auf die Phasengrenzflächenbildung im G-L-System und auch auf die (bio-)chemischen Vorgänge ungünstig auswirken können.So far, the foam has been combated either mechanically Foam destroyers that require shaft penetrations (toxicity, risk of explosion, Sterility) or by adding chemical antifoam agents that affect the Phase boundary formation in the G-L system and also on the (bio) chemical processes can have an unfavorable effect.

Es ist ferner bekannt, zur Gasabscheidung aus G-L-Systemen Schwerkraftabscheider oder Zyklonabscheider zu verwenden.It is also known to use gravity separators for gas separation from G-L systems or a cyclone separator.

Schwerkraftabscheider bewirken im Gravitationskraftfeld nur weitgehende Entgasung bei sehr kleinen abwärts gerichteten L-Geschwindigkeiten, wie z.B. Bild 1 zeigt /5/. Allerdings führen sie nur zu geringen Druckverlusten.Gravity separators only have extensive effects in the gravitational force field Degassing at very low downward L-velocities, e.g. Bild 1 shows / 5 /. However, they only lead to low pressure losses.

Zyklonabscheider gemäß Bild 2 erreichen unter der Wirkung eines Zentrifugalkraftfeldes> das in der Regel mindestens 50 mal sts:rker ist als das Gravitationskraftfeld - oft auch noch verstärkt im Fallrohr (auch "Drallrohr" genannt) - eine wesentlich bessere Entgasung. Infolge der großen Dichtedifferenz werden dabei die Gasblasen B mit der Relativgeschwindigkeit wr in der Drallströmung nach innen und oben gedrängt. Auf diese Weise werden beispielsweise aus wässerigen Systemen Gasblasen mit Durchmessern dz 0,15 bis 0,) mm praktisch vollständig abgeschieden bei Druckverlusten von bp W 0,025 bis 0,05 bar.Cyclone separators according to Figure 2 achieve> under the effect of a centrifugal force field which is usually at least 50 times stronger than the gravitational force field - often reinforced in the downpipe (also called "twist pipe") - an essential one better degassing. As a result of the large difference in density, the gas bubbles become B is pushed inwards and upwards in the swirl flow with the relative speed wr. In this way, for example, aqueous systems become gas bubbles with diameters dz 0.15 to 0.) mm practically completely deposited with pressure losses of bp W 0.025 to 0.05 bar.

Bisher ist es üblich, Zyklonabscheider zur Entgasung von G-L-Systemen gemäß Bild 3 anzuordnen. Hier tritt von dem unten zugeführten Gasstrom G 1 bei Reaktor R 1 der Gasstrom G 2 aus, und zwar teils über die freie Oberfläche O im Reaktor, teils aus dem Zyklon Z. Dieser soll restliche Gasblasen aus dem abgehenden Liquid strom L 2 austreiben. Aufgabe des Zyklons ist dabei eindeutig verbesserte Gasabscheidung, nicht aber Verhütung von Schaumbildung. Sollte nämlich das System zum Schäumen neigen, so könnte sich Schaum ungehindert an der freien Oberfläche O im Reaktor bilden.So far it has been common to use cyclone separators for degassing G-L systems to be arranged according to Figure 3. Here comes from the gas stream G 1 fed in below at the reactor R 1, the gas flow G 2 from, in part via the free surface O in the reactor, partly from the cyclone Z. This is supposed to remove the remaining gas bubbles from the outgoing liquid Drive out current L 2. The task of the cyclone is clearly improved gas separation, but not the prevention of foam formation. If the system tends to foam, so foam could form unhindered on the free surface O in the reactor.

2. Ziel und Beschreibung der Erfindung Das Ziel der vorliegenden Erfindung ist hingegen, Entgasungen von G-L-Systemen so durchzuführen, daß dabei kein Schaum entstehen kann. Das Prinzip dieses Verfahrens und der zu seiner Durchführung geeigneten Vorrichtung wird anhand von Bild 4 beschrieben. Die (bio-)chemische Reaktion oder verfahrenstechnische Operation in einem G-L-System, das auch suspendierte Partikel oder sonstige disperse Phasen enthalten kann, findet hier als Beispiel in einem Schlaufenreaktor R statt. Er besteht aus dem zylindrischen Mantel 1 mit beliebig geformtem Boden 2 und einem konischen Kopf ), der sich nach oben zum Austrittsstutzen 4 hin verengt. Im Schlaufenreaktor R befindet sich ein konzentrisches Leitrohr 5, um das ein Umlauf - insbesondere der L-Phase - stattfindet /1/.2. Object and Description of the Invention The object of the present invention on the other hand, degassing G-L systems should be carried out in such a way that there is no foam can arise. The principle of this procedure and the one suitable for its implementation The device is described using Figure 4. The (bio) chemical reaction or procedural operation in a G-L system that also contains suspended particles or other disperse phases can be found here as an example in one Loop reactor R instead. It consists of the cylindrical shell 1 with any shaped bottom 2 and a conical head), which goes up to the outlet nozzle 4 narrowed down. In the loop reactor R there is a concentric guide tube 5, around which a cycle - especially the L-phase - takes place / 1 /.

Dieser Umlauf wird bewirkt durch Einblasen des Gasstroms G 1 über die G-Düse 6 am Boden des Reaktors hier in den Innenraum (Airlift-Antrieb), und/oder durch Injizieren des Liquidstroms L 1 über die L-DUse 7 mit hoher Geschwindigkeit von wLl > 20 m/s (Strahlantrieb) und/oder durch einen (hier nicht dargestellten) axialfördernden Rührer im Innenraum (Propellerantrieb). Die Antriebsarten können variiert werden z.B. durch Einblasen des Gases unten in den äußeren Ringraum oder Injizieren des L-Strahls von oben nach unten in den Innenraum; sie können aber auch miteinander kombiniert werden.This circulation is brought about by blowing in the gas stream G 1 over the G-nozzle 6 on the bottom of the reactor here in the interior (airlift drive), and / or by injecting the liquid stream L 1 through the L-DUse 7 at high speed of wLl> 20 m / s (jet propulsion) and / or by a (not shown here) axially conveying stirrer in the interior (propeller drive). The drive types can can be varied e.g. by blowing the gas down into the outer annular space or Injecting the L-beam into the interior space from top to bottom; but they can too can be combined with each other.

Entscheidend ist, daß der Reaktor voll erfüllt ist vom G-L-System, in ihm also keine freie Oberfläche vorhanden ist. Aus dem Reaktor R wird der G-L-Strom, bestehend aus G 2 + L 2 über den Austrittsstutzen 4 und eine ansteigende Leitung 8 dem Zyklon Z (oder auch mehreren parallel geschalteten Zyklonen) zugefördert.It is crucial that the reactor is fully fulfilled by the G-L system, there is no free surface in it. From the reactor R becomes the G-L stream, consisting of G 2 + L 2 via the outlet nozzle 4 and a rising line 8 fed to the cyclone Z (or several cyclones connected in parallel).

Im Zyklon Z - und gegebenenfalls auch noch im Fallrohr F - bildet sich die einzige freie Oberfläche 0 des G-L-Systems in der gesamten Anlage, über die allein der Gasstrom G 2 austreten kann, und zwar unter der Wirkung eines Zentrifugalkraftfeldes. Dieses kann erzeugt werden durch Tangentialeinlauf des G-L-Systems in den Zyklon, gegebenenfalls verstärkt durch Tangentialzufuhr eines schnellen L-Stroms, und/oder durch einen schnellaufenden mechanischen Rührer im Zyklon. Anstelle des Zyklons oder zusätzlich kann auch eine Zentrifuge zur Entgasung im Zentrifugalkraftfeld verwendet werden. In jedem Fall darf Gasaustritt aus dem G-L-System nur unter Einwirkung von Zentrifugalkraftfeldern stattfinden! Bläht austretendes Gas eine Flüssigkeitslamelle auf, so wird diese durch Zentrifugal- und Scherkräfte der Drallströmung in statu nascendi wieder zerstört und in das rotierende G-L-System zurückgedrückt. Es kann sich also kein Schaum bilden oder gar aufbauen.Forms in cyclone Z - and possibly also in downpipe F - the only free surface 0 of the G-L system in the entire system which only the gas flow G 2 can exit, under the action of a centrifugal force field. This can be generated by tangential entry of the G-L system in the Cyclone, possibly reinforced by the tangential supply of a fast L-stream, and / or by a high-speed mechanical stirrer in the cyclone. Instead of Cyclones or a centrifuge can also be used for degassing in a centrifugal force field be used. In any case, gas leakage from the G-L system is only allowed under action take place by centrifugal force fields! If escaping gas expands a lamella of liquid on, this is due to centrifugal and shear forces of the swirl flow in statu nascendi destroyed again and pushed back into the rotating G-L system. It can So no foam forms or even builds up.

Die erfindungsgemäße Betriebsweise ermöglicht aber auch z.B.The mode of operation according to the invention also enables e.g.

in Verbindung mit einem Entgasungskopf K gemäß Bild 5 den Gasstrom Gr, der von dem abwärts gerichteten L-Strom Lr in den Ringraum des Schlaufenreaktors R eingezogen wird, zu verringern und zugleich den Gasaustrag aus dem G-L-System im Zyklon Z wie zuvor ohne Schaumbildung durchzuführen.in connection with a degassing head K according to Figure 5 the gas flow Gr, that of the downward L-stream Lr into the annulus of the loop reactor R is drawn in to reduce and at the same time the gas discharge from the G-L system to be carried out in Zyklon Z as before without foam formation.

Entsprechend läßt sich die erfindungsgemäße Betriebsweise verbinden mit allen Apparatetypen, in denen G-L-Systeme behandelt werden, wie Begasungsrührkessel, Blasensäulen, modifizierte Schlaufenreaktoren, z.B. gemäß Bild 6. Hier wird in einem rechteckigen Schlaufenreaktorteil SR nur der Liquidstrom L 5 rezirkuliert, während der Gasstrom G 3 in einem nachgeschalteten Blasensäulenteil BS aufsteigt. Das am Kopf des SR-Teils austretende G-L-Gemisch L 4 + G 4 wird, z.B. mit einer G-L-Pumpe, dem BS-Teil unten zugeführt. Am Kopf des BS-Teils verläßt das Gemisch Lab + Gab den voll vom G-L-System verfüllten Reaktor SR + BS über den Zyklon Z. Hier besteht unter starkem Zentrifugalkraftfeld die einzige freie Oberfläche des Systems, an der ohne Schaumbildung - wie zuvor erläutert - Gab und Lab voneinander getrennt werden. Ein Teilstrom Lr kann ggf. rezirkuliert und mit L 1 dem SR wieder zugeführt werden, z<B. um eine erforderliche L-Strahlleistung für Dispergierung und Umwälzung einzubringen, wie das z.B. die G-L-Düse in Bild 4 und 5 zeigt.The mode of operation according to the invention can be combined accordingly with all types of equipment in which G-L systems are treated, such as stirred gas tanks, Bubble columns, modified loop reactors, e.g. as shown in Figure 6. Here, in one rectangular loop reactor part SR only the liquid flow L 5 recirculates while the gas flow G 3 rises in a downstream bubble column part BS. The on G-L mixture L 4 + G 4 exiting the head of the SR part is, e.g. with a G-L pump, fed to the BS part below. The mixture leaves Lab + Gab at the head of the BS part the SR + BS reactor, which is fully filled by the G-L system, via the Z cyclone the only free surface of the system under a strong centrifugal force field which without foam formation - as explained above - separated gab and rennet from one another will. A partial flow Lr can optionally be recirculated and fed back to the SR with L 1 become, e.g. a required L-beam power for dispersion and circulation as shown e.g. by the G-L nozzle in Figures 4 and 5.
