Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Gewinnung von Synthesegas aus den festen Brennstoffen, die von festen städtischen oder von festen industriellen Abfallen abgeleitet sind.The present invention relates to a process for obtaining synthesis gas from solid fuels derived from solid urban or solid industrial waste.
Die aus festen städtischen Abfällen abgeleiteten festen Brennstoffe (ublicherweise als "refüse derived fuel", "RDF" oder in Italien als "CSdR" bezeichnet) sind der leichteste brennbare Anteil an festen städtischen Abfallen, d.h. sie bestehen aus Kunststoffen, Papier, Holz und Textilien (möglicherweise ist organisches Material zugegen). Diese Brennstoffe weisen je nach Trenngrad und ihrem Feuchtigkeitsgehalt einen Nettoheizwert im Bereich von 10450 kJ bis 18850 kJ/kg (2.500 bis 4.500 kcal/kg) auf.Solid fuels derived from urban solid waste (commonly referred to as "refuse derived fuel", "RDF" or in Italy as "CSdR") are the most easily combustible fraction of urban solid waste, i.e. they consist of plastics, paper, wood and textiles (organic material may be present). These fuels have a net calorific value ranging from 10450 kJ to 18850 kJ/kg (2500 to 4500 kcal/kg), depending on the degree of separation and their moisture content.
Ein allgemeines Schema des Verfahrens zur Herstellung dieses RDF umfaBt die folgenden Vorgänge:A general scheme of the process for producing this RDF includes the following operations:
- Zerkleinerung des festen städtischen Abfalls;- Shredding of solid urban waste;
- magnetische Trennung;- magnetic separation;
- Luftsoftieren zur Trennung der leichten von den schweren Fraktionen;- Air softening to separate the light from the heavy fractions;
- Trocknen des Leichtnaterials;- Drying of the lightweight material;
- eventuelles Pelletisieren des entstehenden Produuts.- possible pelletizing of the resulting product.
Zu den vielen Faktoren zur Differentierung von RDF zählt neben der Zusammensetzung der als Ausgangsmaterial verwendeten festen städtischen Abfalle die zur Auswahl des abgeleiteten Brennstoffs verwendete Technologie.Among the many factors differentiating RDF are the composition of the municipal solid waste used as feedstock and the technology used to select the derived fuel.
Ein Verwendungszweck dieses RDF ist das Verbrennen in Boilern und vor allem in Zementfabriken.One use of this RDF is combustion in boilers and especially in cement factories.
Die Anmelderin hat nun gefunden, daß dieser RDF oder diese festen industriellen Abfälle unter geeigneten Bedingungen vergast werden können, um Synthesegas zu erhalten.The applicant has now found that this RDF or this solid industrial waste can be gasified under suitable conditions to obtain synthesis gas.
Die vorliegende Erfindung schafft daher ein Verfahren zum Vergasen der brennbaren Fraktion von festen städtischen oder industriellen Abfallen zur Ausbildung von Synthesegas durth Vergasen mit einem unter Druck stehenden sauerstoffhältigen Gas bei einer Mindesttenperatur von 1000º C, dadurch gekennzeichnet, daß es die folgenden Stufen umfaßt:The present invention therefore provides a process for gasifying the combustible fraction of solid urban or industrial waste to form synthesis gas by gasification with a pressurized oxygen-containing gas at a minimum temperature of 1000ºC, characterized in that it comprises the following steps:
- Zuführen der genannten brennbaren Fraktion und von technisch reinem Sauerstoff, der auf einen Druck von 0,1 NPa bis 10 MPa (eine Atmosphäre absolut bis 100 Atmosphären absolut) gebracht worden ist, im Gleichstrom zu einem adiabatischen Vergaser und- feeding the said combustible fraction and technically pure oxygen, which has been brought to a pressure of 0.1 NPa to 10 MPa (one atmosphere absolute to 100 atmospheres absolute), in cocurrent to an adiabatic gasifier and
- Waschen des gebildeten Synthesegases zur Abtrennung der sauren gasförmigen Komponenten.- Washing the synthesis gas produced to separate the acidic gaseous components.
Es wird sowohl im Falle von RDF als auch im Falle von festen industriellen Abfällen ein Nettoheizwert von mindestens 12560 kJ/kg (3.000 kcal/kg) und ein Feuchtigkeitsgehalt unter oder maximal gleich 30 % empfohlen.A net calorific value of at least 12560 kJ/kg (3000 kcal/kg) and a moisture content of less than or equal to 30% are recommended for both RDF and solid industrial waste.
Von den verwendbaren festen industriellen Abfällen sind insbesondere Altreifen zu erwähnen; es kam jedenfalls auch jede andere Art von industriellen Abfällen gewählt werden.Of the solid industrial wastes that can be used, old tires are particularly worth mentioning; however, any other type of industrial waste could also be chosen.
Was den Vergaserdruck betrifft, so liegt der bevorzugte Bereich bei Verwendung von RDF bei 1,5 MPa bis 5 MPa (15 bis 50 abs.atm) und bei Verwendung von festen industriellen Abfällen bei 0,1 MPa bis 5 MPa (1 bis 50 abs.atm).Regarding gasifier pressure, the preferred range is 1.5 MPa to 5 MPa (15 to 50 abs.atm) when using RDF and 0.1 MPa to 5 MPa (1 to 50 abs.atm) when using solid industrial waste.
Die Temperatur des Vergasers wird sowohl als Fnnktion des Feuchtigkeitsgehaltes des RDF oder der industriellen Abfälle als auch ihres Heizwertes und als Funktion der enge und der Temperatur des in das Verfahren eingespeisten Sauerstoffs bestimmt.The temperature of the gasifier is determined both as a function of the moisture content of the RDF or industrial waste and its calorific value and as a function of the pressure and temperature of the oxygen fed into the process.
Bevor der Sauerstoff in den Vergaser eingespeist wird, kam er auf eine Temperatur gleich der oder höher als die Temperatur dieses Vergasers vorgewännt werden.Before the oxygen is fed into the carburetor, it must be preheated to a temperature equal to or higher than the temperature of this carburetor.
Dieser Sauerstoff kann beispielsweise in einer Luftfraktionierungsvorrichtung oder in einer äquivalenten Vorrichtung hergestellt werden.This oxygen can be produced, for example, in an air fractionation device or in an equivalent device.
In einem solchen Fall kam die Verwendung eines Teiles des erhaltenen Synthesegases (wie z. B. etwa 10 %) als für den Betrieb dieser Luftfraktionierungsvorrichtung oder einer äquivalenten Vorrichtung erforderlichen Energiequelle vorteilhaft sein.In such a case, it may be advantageous to use a portion of the synthesis gas obtained (such as about 10%) as the energy source required to operate this air fractionation device or an equivalent device.
Die Behandlung des aus dem Vergaser austretenden Gases zur Entfernung der sauren Gase kam beispielsweise durch eine Waschstufe mit Nätriumhydroxid durchgeführt werden.The treatment of the gas leaving the gasifier to remove the acidic gases could be carried out, for example, by a washing stage with sodium hydroxide.
Weiters kann das Abkühlen des aus dem Vergaser austretenden Gases vor einer solchen Behandlung von Vorteil sein.Furthermore, cooling the gas exiting the carburetor before such treatment can be beneficial.
Es werden nun einige Beispiele angefikirt, um die Erfindung näher zu erläutern, ohne sie zu beschränken.Some examples are now given to explain the invention in more detail, without limiting it.
