Zur Ermittlung von Gasbestandteile steht als bekanntes Verfahren die Messung mittels Gaschromatographen zur Verfügung. Dieses Verfahren liefert gute Ergebnisse, ist aber technisch kompliziert, verursacht hohe Investitions- und Betriebskosten und ist wegen der zeitverzögerten Auswertung für Online-Bestimmung bestenfalls eingeschränkt geeignet. Für industrielle Anwendungen, insbesondere für Regelungszwecke ist dieses Verfahren bezüglich der Ansprechzeit zu träge. Eine ständig laufende Onlinemessung der Gasbestandteile und der Gaseigenschaften ist insbesondere dann erforderlich, wenn diese Messwerte zur Regelung von kontinuierlich arbeitenden Vergaseranlagen eingesetzt werden sollen.to Determination of gas components is known as the method Measurement by gas chromatograph available. This method provides good results, but is technically complicated, causes high Investment and operating costs and is due to the time-delayed evaluation for online determination at best limited suitable. For industrial applications, especially for regulatory purposes is this Procedures regarding the response time too slow. One constantly ongoing online measurement of gas components and gas properties is especially necessary if these readings are for regulation be used by continuously operating carburetor systems should.
Weiterhin bekannt sind photometrische Verfahren zur Brennwertbestimmung mittels der Infrarotabsorption von Gasbestandteilen. Diese Messverfahren liefern online sehr genaue Messergebnisse für die im Gas enthaltenen Kohlenwasserstoffe – Methan CH4 und höhere –, Kohlenmonoxid CO, Schwefelwasserstoff SH2 sowie als nicht brennbare Bestandteile Kohlendioxid CO2 und Wasserdampf H2O. Nicht hinreichend genau gemessen werden können durch Infrarotabsorption homonukleare Moleküle, insbesondere die in den Brenngasgemischen enthaltenen Gase Stickstoff N2, der Wasserstoff H2 und der Sauerstoff O2.Also known are photometric methods for calorific value determination by means of the infrared absorption of gas components. These measuring methods provide online very accurate measurement results for the hydrocarbons contained in the gas - methane CH 4 and higher -, carbon monoxide CO, hydrogen sulfide SH 2 as well as non-flammable constituents carbon dioxide CO 2 and water vapor H 2 O. Can not be measured with sufficient accuracy by infrared absorption homonuclear Molecules, in particular the gases contained in the fuel gas mixtures nitrogen N 2 , the hydrogen H 2 and the oxygen O 2 .
Weiterhin bekannt ist ein Verfahren zur Messung von Erdgas bei denen die photometrische Messung durch die Messung weiterer Gaseigenschaften, z. B. der Wärmeleitfähigkeit, ergänzt wird und damit als homonuklearer Gasbestandteil der Stickstoffanteil N2 errechnet wird. Dieses Messverfahren ist damit jedoch auf ein bestimmtes Brenngas, das Erdgas, beschränkt, da Erdgas keine weiteren homonuklearen Bestandteile enthält (H2 und O2 sind im Erdgas nicht enthalten).Also known is a method for measuring natural gas in which the photometric measurement by the measurement of other gas properties, eg. B. the thermal conductivity, is supplemented and thus calculated as a homonuclear gas component of the nitrogen content N 2 . However, this measurement method is therefore limited to a specific fuel gas, the natural gas, since natural gas contains no other homonuclear constituents (H 2 and O 2 are not contained in natural gas).
Die
Gasbestandteile und die Gaseigenschaften von allgemeinen Brenngasen,
z. B. aus der Feststoffvergasung, kann mit diesen oben beschriebenen
bekannten Verfahren nicht online bestimmt werden. Allgemeines Brenngas
hat im Wesentlichen folgende Bestandteile (Die Angaben der Volumenprozente
beziehen sich hierbei auf mit Luft vergaste Biomasse):
Aufgabe der Erfindung ist es, ein Verfahren auf Basis von marktgängigen Infrarotdetektoren und weiteren Messgeräten ein Verfahren zu entwickeln, das eine kostengünstige Onlinemessung der Gasbestandteile von Brenngasen, z. B. aus Feststoffvergasung ermöglicht. Aufgabe der Erfindung ist es weiterhin, eine einfache und praktisch einsetzbare Messanordnung zu schaffen.task The invention is a method based on commercially available infrared detectors and other measuring devices to develop a process that provides a cost-effective online measurement of the gas constituents of Fuel gases, z. B. made possible by solid gasification. Object of the invention It continues to be a simple and practical measuring arrangement to accomplish.
Bei dem erfindungsgemäßen Verfahren zur Bestimmung der Gasbestandteile und der Gaseigenschaften von Brenngas werden folgende Komponenten eingesetzt:
- 1. Ein optisches System aus einem breitbandig emittierenden Infrarotstrahler (1 μm bis 6μm) und schmalbandigen Empfängern zur Messung der IR-Absorption der im Brenngas enthaltenen IR-aktiven Komponenten,
- 2. ein Kalorimeter zur Heizwertbestimmung,
- 3. eine Lambdasonde zur Bestimmung des Sauerstoffanteils,
- 4. ein Volumenflussmessgerät beliebiger Bauart,

- 4. a volumetric flow meter of any design,
- 5. a temperature measurement and
- 6. a pressure measurement
Dabei wird das Brenngas in dem Infrarotabsorptionsmesssystem einer Infrarotstrahlung im Frequenzbereich (1μm bis 6μm) ausgesetzt und für mehrere Wellenlängen oder spektrale Bereiche der vom Brenngas absorbierte Anteil erfasst.The fuel gas in the infrared absorption measuring system is exposed to infrared radiation in the frequency range (1 .mu.m to 6 .mu.m) and for several wavelengths or spectral ranges of the fuel gas absorbed share.
Grundlage des Messverfahrens ist, dass die zu bestimmenden Gase (mit Ausnahme der homonuklearen Bestandteile Wasserstoff Sauerstoff und Stickstoff) ein Dipolmoment besitzen, d. h. sie absorbieren elektromagnetische Strahlung.basis the measuring method is that the gases to be determined (except the homonuclear constituents hydrogen oxygen and nitrogen) have a dipole moment, i. H. they absorb electromagnetic Radiation.
Die
Absorption der einzelnen Gasbestandteile im nahen infraroten Spektralbereich
ist spezifisch für das
betreffende Gas und proportional zur Anzahl der absorbierenden Moleküle. Der
nicht absorbierte (transmittierte) Anteil der Strahlung lässt sich
nach dem Lambert Beerschen Gesetz bestimmen.
Mit:
- I
- = gemessene Intensität der Strahlung nach Absorption im Gas
- I0
- = Intensität der Strahlung vor Absorption im Gas
- N
- = Teilchenzahldichte in der Absorptionsstrecke
- μ
- = gasspezifischer Absorptionskoeffizient (wellenlängenabhängig)
- d
- = Länge der Absorptionsstrecke
- I
- = measured intensity of the radiation after absorption in the gas
- I 0
- = Intensity of the radiation before absorption in the gas
- N
- = Particle number density in the absorption path
- μ
- = gas-specific absorption coefficient (wavelength-dependent)
- d
- = Length of the absorption path
Im
Transmissionsspektrum im Wellenbereich zwischen 1 und 6μm existieren
Absorptionsbanden, die jeweils von den Gasbestandteilen herrühren. Die
Stärke
der Absorption ist direkt proportional zum Partialdruck des betreffenden
Gases.
Die Transmission der einzelnen IR-aktiven Bestandteile des Brenngases wird für jedes Gas einzeln in Abhängigkeit des Partialdrucks im Spektralbereich zwischen 1 und 6μm bestimmt. Aus der gemessenen Transmission wird mit Hilfe einer Eichung/Kalibrierung, der Partialdruck des betreffenden Gases bestimmt.The Transmission of the individual IR-active constituents of the fuel gas is for each gas individually depending the partial pressure in the spectral range between 1 and 6μm determined. The measured transmission is measured by means of a calibration / calibration, determines the partial pressure of the gas in question.
Die zur Bestimmung des Partialdrucks der Brenngasbestandteile verwendeten Spektralbereiche sind vorzugsweise:
- 1. 3,2–3,45 μm zur Bestimmung von CH4
- 2. 3,2–3,5 μm zur Bestimmung der höheren Kohlenwasserstoffe
- 3. 4,2–4,3 μm zur CO2 -Messung
- 4. 4,4–4,8 μm zur CO-Messung
- 5. 2,5–2,8 μm zur Messung des Wasserdampfes
- 6. 3,7–4,4 μm zur Messung des Schwefelwasserstoffs und
- 7. ein Referenzkanals, in dem alle gemessenen Gase nicht oder nur schwach absorbieren,
- 1. 3.2-3.45 μm for the determination of CH 4
- 2. 3.2-3.5 microns for the determination of higher hydrocarbons
- 3. 4.2-4.3 μm for CO 2 measurement
- 4. 4.4-4.8 μm for CO measurement
- 5. 2.5-2.8 microns for measuring the water vapor
- 6. 3.7-4.4 microns for the measurement of hydrogen sulfide and
- 7. a reference channel in which all measured gases do not absorb or only weakly absorb,
Dabei verhindert die Auswertung des Referenzkanals eine mögliche Verfälschung der Transmissionsmessung, die durch diffuse Streuung der Infrarotstrahlung aufgrund der Verschmutzung an Ein- und Austrittsfenster oder durch im Brenngas enthaltene Schwebstoffe wie Russ oder Staub entsteht.there the evaluation of the reference channel prevents possible corruption the transmission measurement, the diffuse scattering of the infrared radiation due to contamination at entrance and exit windows or through suspended matter contained in the fuel gas such as soot or dust is formed.
Die Überlagerung von Absorptionsbanden verschiedener zu messender Gase, wie z. B. den überlagerten Banden der verschiedenen CnHm oder die Überlagerung des CO2 Spektrums mit dem Spektrum von H2S werden wie folgt entfaltet. Die Anzahl und die Spektralbereiche der Infrarotempfänger werden so gewählt, dass die gemessene Gesamtabsorption hauptsächlich durch die Absorption nur der zu bestimmenden Einzelstoffe hervorgerufen wird und die Anzahl der gemessenen Spektralbereiche mindestens der Anzahl der zu messenden Einzelstoffe ist. Hieraus lässt sich ein Gleichungssystem aus m-Gleichungen mit n-Unbekannten (mit m >= n) aufstellen, das mathematisch gelöst werden kann. Ergebnis der Auswertung sind die Partialdrücke der IR-aktiven Einzelstoffe.The superposition of absorption bands of different gases to be measured, such. B. the superimposed bands of the different C n H m or the superposition of the CO 2 spectrum with the spectrum of H 2 S are unfolded as follows. The number and the spectral ranges of the infrared receivers are chosen such that the measured total absorption is mainly caused by the absorption of only the individual substances to be determined and the number of spectral ranges measured is at least the number of individual substances to be measured. From this a system of equations of m equations with n unknowns (with m> = n) can be established, which can be solved mathematically. The result of the evaluation are the partial pressures of the IR-active individual substances.
Zur vollständigen Bestimmung des Gasbestandteile müssen zusätzlich die Partialdrücke bzw. Anteile der homonuklearen Moleküle im Gasgemisch (Sauerstoff O2, Wasserstoff H2 und Stickstoff N2) bestimmt werden.
- – Hierbei wird der Partialdruck des Sauerstoffs O2 direkt mit einer Lambdasonde gemessen.
- – Für die Bestimmung des H2-Partialdrucks wird zunächst mit Hilfe des Kalorimeters der Heizwert des Gasgemischs bestimmt. Aus dem so gemessenen Gesamtheizwert lässt sich unter Abzug des Heizwertes der photometrisch ermittelten brennbaren Gasbestandteile der Heizwert des H2-Anteils errechnen und daraus wiederum der Partialdruck des H2-Anteils bestimmen.
- – Als letzte zu bestimmende Größe ist alsdann der Partialdruck des N2-Anteils zu bestimmen. Da außer dem N2-Anteil alle Partialdrücke der Einzelstoffe im Brenngas ermittelt sind, lässt sich der N2- Partialdruck aus der Differenz zwischen dem gemessenen Gesamtdruck und der Summe der anderen Partialdrücke ermitteln.
- - Here, the partial pressure of the oxygen O 2 is measured directly with a lambda probe.
- - For the determination of the H 2 partial pressure, the calorific value of the gas mixture is first determined with the help of the calorimeter. From the total calorific value measured in this way, the calorific value of the H 2 fraction can be calculated and deducted, subtracting the calorific value of the photometrically determined combustible gas constituents again determine the partial pressure of the H 2 share.
- - As the last variable to be determined, the partial pressure of the N 2 component must then be determined. Since, apart from the N 2 content, all partial pressures of the individual substances in the fuel gas are determined, the N 2 partial pressure can be determined from the difference between the measured total pressure and the sum of the other partial pressures.
Auf Basis dieser vollständigen Analyse der Brenngasbestandteile lassen sich weitere Gaseigenschaften wie die Wobbezahl und die Methanzahl mathematisch ermitteln.On Base of this complete Analysis of the fuel gas components can be further gas properties how to mathematically determine the Wobbe number and the methane number.
Die Bestimmung der Energiedurchflussmenge erfolgt mathematisch durch Multiplikation der gemessenen Durchflussvolumens mit dem gemessenen Heizwert.The Determination of the energy flow rate is mathematically by Multiplication of the measured flow volume with the measured Calorific value.
