Description
Die Erfindung betrifft eine Flugstromvergasungseinrichtung, bei der Karbonatablagerungen an den Wärmeübertragerflächen von Wärmetauschern im Quenchwasserkreislauf minimiert sind.The invention relates to an entrainment gasification device in which carbonate deposits on the heat transfer surfaces of heat exchangers in the quench water circulation are minimized.

Zur Verbesserung der Effizienz des Vergasungsprozesses ist es von Vorteil, das Quenchwasser vor der Eindüsung in den Quencher vorzuwärmen. Bei dieser Aufwärmung kommt es allerdings zu der bekannten Ablagerung von Karbonaten der Härtebildner auf der Wärmetauscherfläche, die den Wärmeübergang behindern. Mit der daraus resultierenden geringeren Vorwärmung des Quenchwassers können die Rohgasparameter am Ausgang (
Bekannt sind die Entkarbonisierung des Prozesswassers durch Zudosierung von Ca(OH)2, die Vollentsalzung, die Verwendung von Ionenaustaucher und die Absenkung des pH-Wertes durch Zugabe einer preisgünstig verfügbaren Säure (HCl, H2SO4).The decarbonization of the process water by addition of Ca (OH) 2 , demineralization, the use of ion exchangers and the lowering of the pH by addition of an inexpensive available acid (HCl, H 2 SO 4 ) are known.

Für den der Erfindung zugrunde liegenden Einsatzfall der Quenchwasservorwärmung sind die zuvor genannten Verfahren jedoch nicht anwendbar bzw. nur mit sehr großem technischem und finanziellem Aufwand umsetzbar. Bei der Entkarbonisierung sind zusätzliche anlagentechnische Vorkehrungen zur Abscheidung der gefällten Karbonate zu treffen. Da auch Magnesium als Härtebildner gefällt werden muss führt die damit verbundene Anhebung des pH-Wertes des Prozesswassers/Quenchwassers zur Veränderung des pH-Wertes des Quenchprozesses, was Ablagerungen/Störungen des Rohgasweges nach dem Quencher zur Folge hat. Die Verwendung von Ionenaustauscher muss aufgrund der Feststoffbeladung des zu behandelnden Wassers ausgeschlossen werden. Auch die Verwendung der Säuren HCl oder H2SO4 ist nicht zielführend, da der Einsatz zu erhöhten Werkstoffanforderungen führt und zudem die Verwendung von H2SO4 die Gipsbildung befördert.However, for the invention underlying application of Quenchwasservorwärmung the aforementioned methods are not applicable or can be implemented only with great technical and financial effort. During decarbonisation, additional plant engineering measures must be taken to separate the precipitated carbonates. Since magnesium must also be precipitated as a hardener, the associated increase in the pH of the process water / quench water leads to a change in the pH value of the quench process, which leads to deposits / disruptions of the crude gas path after the quencher. The use of ion exchangers must be excluded due to the solids loading of the water to be treated. The use of the acids HCl or H 2 SO 4 is not effective because the use leads to increased material requirements and also promotes the use of H 2 SO 4 gypsum formation.
Der Erfindung liegt das Problem zugrunde, für eine Flugstromvergasungsanlage einen Quenchwasserkreislauf anzugeben, bei dem Karbonatablagerungen an den Wärmeübertragerflächen von Wärmetauschern minimiert sind, der nur geringen Aufwand erfordert und hinsichtlich Nebenwirkungen unproblematisch ist.The invention is based on the problem of specifying a Quenchwasserkreislauf for an entrained flow gasification plant, are minimized in the carbonate deposits on the heat exchanger surfaces of heat exchangers, which requires little effort and is unproblematic in terms of side effects.
Das Problem wird durch einen Quenchwasserkreislauf mit den Merkmalen des Schutzanspruchs 1 gelöst.The problem is solved by a Quenchwasserkreislauf with the features of the protection claim 1.
Erfindungsgemäß wird im Quenchwasserkreislauf einer Vergasungsanlage dem Quenchwasser nach der Druckerhöhung und vor der Erwärmung gezielt Kohlendioxid zugegeben.According to the invention, in the quench water circuit of a gasification plant, carbon dioxide is selectively added to the quench water after the pressure has been increased and before heating.
Die Erfindung macht sich die Erkenntnis zunutze, dass die Ursache der Ablagerungen die Störung des Kalk-Kohlensäuregleichgewichtes im Prozesswasser während des Aufwärmprozesses ist. Bei konstantem Druck wird mit der Erhöhung der Temperatur die Löslichkeit von Kohlendioxid verringert, während bei konstanter Temperatur mit der Druckerhöhung die Löslichkeit von Kohlendioxid erhöht wird. The invention takes advantage of the finding that the cause of the deposits is the disturbance of the lime-carbonic acid balance in the process water during the warm-up process. At constant pressure, the increase in temperature reduces the solubility of carbon dioxide, while at constant temperature as the pressure increases, the solubility of carbon dioxide is increased.
Unter Ausnutzung dieser druck- und temperaturabhängigen Löslichkeit von Kohlendioxid (CO2) in Wasser wird, nach der Druckerhöhung des Prozesswassers unter Verwendung einer Pumpe
Dem Vergasungsprozess ist generell eine Gasreinigungsanlage nachgeordnet, in der auch Kohlendioxid selektiv abgetrennt wird. Dieses Kohlendioxid steht kostenlos in ausreichender Menge zur Verfügung und es bedarf nur einer Verdichtung auf den Betriebsdruck des Prozesswassers zur Injektion in das Wasser. Das zugegebene Kohlendioxid verbleibt in dem geschlossenen Wasserkreislauf bzw. gelangt wieder in das Rohgas des Vergasungsprozesses, stellt somit keine zusätzliche Emissionsquelle dar.The gasification process is generally followed by a gas purification plant, in which carbon dioxide is selectively separated. This carbon dioxide is available free of charge in sufficient quantity and it only requires a compression to the operating pressure of the process water for injection into the water. The added carbon dioxide remains in the closed water cycle or gets back into the raw gas of the gasification process, thus represents no additional source of emissions.
