Process for determining the gas quality of sample gas e.g. fuel gas using spectroscopic process comprises determining the pressure and temperature of sample gas, forming spectral vector and multiplying spectral vector with factor vector
Process for determining the gas quality of a sample gas using a spectroscopic process comprises determining the pressure and temperature of the sample gas; forming a spectral vector S in a number of spectral regions by integrating values of the transmission spectrum of the gas; and multiplying the spectral vector S with a factor vector V obtained by calibration measurements of the spectral vector on calibrating gases of known properties and under known conditions to determine a physical parameter for the gas quality. Preferred Features: The factor vectors are determined by calibration measurements carried out on calibrating gases of known properties and under known conditions.
