Description
Gegenstand der vorliegenden Erfindung ist ein Verfahren zum nassen Entfernen von Schwefeldioxid aus Rauchgasen unter Verwendung einer Kalkstein enthaltenden Absorpti onsmittelsuspension, bei demThe present invention relates to a method for wet removal of sulfur dioxide from flue gases using an absorbent containing limestone onsmittelspension, at which
- a) im Sumpf einer Vorstufenabsorption im pH-Bereich von 4 bis 5 durch Einleiten von Luft in die Suspension Sulfit zum Sulfat oxidiert und grobkörniger Gips als feststoffreiche Suspension aus dem System ausge schleust wird,a) in the swamp of a precursor absorption in the pH range of 4 to 5 by introducing air into the suspension Oxidized sulfite to sulfate and coarse-grained gypsum as high-solids suspension out of the system is smuggled
- b) in einer Nachstufenabsorption im pH-Bereich von ca. 6 das Schwefeldioxid des Rauchgases durch die Absorp tionsmittelsuspension als Sulfit gebunden und diese in einem Ablauf separat aufgefangen und in den Vor ratstank für die Absorptionsmittelsuspension zurück geführt wird,b) in a post-stage absorption in the pH range of approx. 6 the sulfur dioxide of the flue gas through the absorber agent suspension bound as sulfite and this collected separately in one process and in the fore Council tank back for the absorbent suspension to be led,
- c) die Wasserverluste der Vorstufenabsorption durch den feststoffarmen Überlauf des Absorptionsmittels aus geglichen,c) the water losses of the precursor absorption by the low solids overflow of the absorbent compared
- d) die Wasserverluste der Nachstufenabsorption durch das Waschwasser einer nachgeschalteten Tropfenabschei dung ausgeglichen werden.d) the water losses due to post-stage absorption the wash water of a downstream droplet separator be balanced.
Ein derartiges Verfahren ist beispielsweise bekannt aus der DE-OS 30 11 592.5. Derartige Anlagen werden von der Anmelderin seit Jahren angeboten und gebaut. Bei diesen Anlagen sind in einem Turm von unten nach oben überein ander gebaut der Sumpf der Vorstufenabsorption, die Sprühanlagen für die Vorstufenabsorption, die schüssel artige Vorrichtung zum separaten Auffangen der Absorp tionsmittelsuspension der Nachstufenabsorption, die Sprüheinrichtungen der Nachstufenabsorption sowie die Tropfenabscheidung. Such a method is known for example from DE-OS 30 11 592.5. Such systems are used by the Applicant offered and built for years. With these Systems are in a tower from bottom to top others built the swamp of precursor absorption, the Sprayers for pre-stage absorption, the bowl like device for collecting the Absorp separately agent suspension of post-stage absorption, the Sprayers of post-stage absorption as well as the Drop separation.
Dieses Verfahren und diese Vorrichtungen haben sich ausgezeichnet bewährt. Sie weisen jedoch den Nachteil auf, daß bei Rauchgasen mit hohem Chloridgehalt ein unerwünscht hoher Anteil des Chlorids auch in die Nach stufenabsorption gelangt. Ein hoher Chloridgehalt in der Absorptionsmittelsuspension der Nachstufenabsorpti on ist jedoch unerwünscht und kann das Absorptionsver mogen der Suspension beeinträchtigen. Der Chloridgehalt des Rauchgases wird bei diesen Verfahren an sich voll ständig von der Vorstufenabsorption abgefangen, jedoch wird durch den Rauchgasstrom stets eine gewisse Menge des Absorptionsmittels der Vorstufenabsorption in den Kreislauf der Nachstufenabsorption mitgerissen, so daß auf diesem mechanischen Wege Chlorid in die Absorpti onsmittelsuspension der Nachstufenabsorption gelangt.This method and these devices have become proven excellent. However, they have the disadvantage on that with flue gases with a high chloride content undesirably high proportion of the chloride also in the night step absorption arrives. A high chloride content in the absorbent suspension of the post-stage absorpti however is undesirable and can absorb the absorption may affect the suspension. The chloride content the flue gas itself becomes full in these processes constantly intercepted by precursor absorption, however is always a certain amount due to the flue gas flow of the absorbent of the precursor absorption in the Cycle of post-absorption absorbed, so that in this mechanical way chloride into the absorpti onsuspension of the post-stage absorption.
Die Erfindung hat sich daher zunächst einmal die Auf gabe gestellt, die Menge an mitgerissenem Chlorid aus der Vorstufenabsorption zu verringern und dadurch das Gesamtverfahren auch bei hohem Chloridgehalt des Rauch gases voll wirksam zu gestalten. Die Erfindung hat sich weiterhin die Aufgabe gestellt, den Verbrauch an Pro zeßwasser zu senken.The invention has therefore first of all the given the amount of entrained chloride to reduce the precursor absorption and thereby the Overall process even with high chloride content in the smoke make gases fully effective. The invention has continued the task of consuming Pro to lower zeßwasser.
Diese Aufgaben können überraschend einfach dadurch ge löst werden, daß die Rauchgase vor der Vorstufenabsorp tion einer Vorwäsche mit Meerwasser und/oder Salzwasser unterzogen werden.These tasks can be surprisingly simple be resolved that the flue gases in front of the pre-absorber prewash with sea water and / or salt water be subjected.
Konstruktiv bedeutet dies, daß vor der Rauchgasent schwefelungsanlage noch ein Vorwäscher mit Sprühein richtungen sowie einem Tropfenabscheider geschaltet ist, der mit Meerwasser und/oder Salzwasser betrieben wird. Constructively, this means that in front of the flue gas sulphurization plant still a pre-washer with spray directions and a droplet separator is operated with sea water and / or salt water becomes.
Es hat sich nämlich überraschenderweise herausgestellt,Surprisingly, it turned out
daß durch die erfindungsgemäße Vorwäsche mit Meerwasser und/oder Salzwasser der Gehalt an Chlorid und Fluorid in den Rauchgasen so stark verringert, daß in der ei gentlichen Rauchgasentschwefelungsanlage nahezu kein Chlorid und Fluorid mehr in der Gasphase vorhanden ist.that by the prewash according to the invention with sea water and / or salt water the chloride and fluoride content so greatly reduced in the flue gases that in the egg conventional flue gas desulfurization plant almost none Chloride and fluoride are more present in the gas phase.
Insbesondere um eine Verunreinigung der Rauchgasent schwefelungsanlage durch Meerwasser und/oder Salzwasser zu vermeiden, wird vorzugsweise zwischen der Vorwäsche und der Vorstufenabsorption eine Tropfenabscheidung durchgeführt. Der hohe Chloridgehalt von Meerwasser und/oder Salzwasser führt nicht zu der an sich zu er wartenden Erhöhung des Chloridgehaltes in Rauchgasen,In particular, contamination of the smoke gas sulfurization plant by sea water and / or salt water to avoid is preferably between the prewash and droplet separation of the precursor absorption carried out. The high chloride content of sea water and / or salt water does not lead to it itself waiting increase in the chloride content in flue gases,
sonder sogar zu einer nahezu vollständigen Auswaschung der Chloride und Fluoride aus den Rauchgasen.but even to an almost complete washout the chlorides and fluorides from the flue gases.
Das erfindungsgemäße Verfahren kann besonders vorteil haft dort eingesetzt werden, wo Meerwasser und/oder Salzwasser in ausreichenden Mengen zur Verfügung steht.The method according to the invention can be particularly advantageous be used wherever sea water and / or Salt water is available in sufficient quantities.
Durch die erfindungsgemäße Maßnahme der Vorwäsche mit Meerwasser und/oder Salzwasser vermindert sich der Be darf an Prozeßwasser erheblich, da die Rauchgase bei der Vorwäsche mit Meerwasser und/oder Salzwasser abge kühlt und mit Wasserdampf beladen werden und damit für die Rauchgasentschwefelung konditioniert werden. Nach dem Stand der Technik mußte diese Wassermenge zusätz lich als Prozeßwasser dem Verfahren zugeführt werden.The measure of prewashing according to the invention Sea water and / or salt water reduce the loading is allowed to process water considerably, since the flue gases at the prewash with sea water and / or salt water cools and be loaded with water vapor and thus for the flue gas desulfurization must be conditioned. To this amount of water had to be additional to the state of the art Lich the process water supplied to the process.
Insbesondere in südlichen Ländern mit hohen Kosten für Prozeßwasser, aber ausreichenden Mengen an Meerwasser und/oder Salzwasser ist dies ein wesentlicher wirt schaftlicher Vorteil. Aber selbst an Standorten mit ausreichenden Mengen von Prozeßwasser kann das erfin dungsgemäße Verfahren vorteilhaft eingesetzt werden, um einen chloridarmen bzw. chloridfreien Gips zu erhalten.Especially in southern countries with high costs for Process water, but sufficient amounts of sea water and / or salt water this is an essential host economic advantage. But even at locations sufficient quantities of process water can do this methods according to the invention are advantageously used to to get a low-chloride or chloride-free plaster.
Die Vorwäsche erfolgt dann mit einem künstlich herge stellten Salzwasser. The prewash is then carried out with an artificial herge provided salt water.
Durch die Absorption der Chloride und Fluoride aus den Rauchgasen sinkt der pH-Wert des Salzwassers und/oder Meerwassers. Es kann daher erforderlich sein, diesen gesunkenen pH-Wert anschließend durch Zugabe von Lauge zu neutralisieren. Bei Verwendung von Natronlauge ent steht weiteres Kochsalz. Bei Verwendung von Calciumhy droxid und/ oder Calciumcarbonat entsteht Calciumchlo rid, das ebenfalls problemlos in das Meer zurückgelei tet werden kann. Insbesondere durch den hohen Gehalt an Chlorid und den niedrigen pH-Wert des Meer- und/oder Salzwassers wird in der Vorwaschstufe praktisch kein Schwefeldioxid ausgewaschen, so daß auch aus diesem Grunde einer Rückleitung des benutzten Meerwassers ins Meer nichts im Wege steht.Due to the absorption of chlorides and fluorides from the Flue gases decrease the pH value of the salt water and / or Sea water. It may therefore be necessary to do so then the pH dropped by adding lye to neutralize. When using caustic soda ent there is more table salt. When using calcium hy droxid and / or calcium carbonate calcium chlo rid, which also easily returned to the sea can be tet. Especially because of the high content of Chloride and the low pH of the sea and / or Salt water is practically none in the prewash stage Sulfur dioxide washed out, so that from this Due to a return of the used sea water to the Nothing stands in the way of the sea.
Das erfindungsgemäße Verfahren ist in der anliegenden Fig. 1 näher erläutert.The method according to the invention is explained in more detail in the attached FIG. 1.
