Abstract
The objective of the project was to investigate the usefulness of FTIR (Fourier Transform InfraRed) absorption spectrometry for analysis of flue gas components. By means of a constructed apparatus for preparation of synthetic flue gas mixtures and a FTIR-spectrometer, infrared absorption spectrums of typical flue gas components/mixtures were recorded. A comparison of the IR-absorption spectrum of the different flue gas components, showed that only the components carbon dioxide and water had absorption at selective substance specific wave numbers. The absorption spectrum of all other flue gas components had interference from either water or carbon dioxide. However this interference could be reduced considerably by using spectrum subtraction or multivariate calibration with PLS (Partial Least Squares). Investigation of the relationship absorbency (at discrete wavenumbers) versus concentration of the different flue gas components, showed a nonlinear relationship for many substances. The limiting factor at which accuracy and sensitivity the respective flue gas components could be analysed, is in most cases depending on the water concentration in the sample. The FTIR-method can also with advantage be used for the analysis of hydrocarbons in the flue gas, eg methane and ethene. By optimization of the wave number resolution, type of radiation source, measuring path length
