Abstract
In the present work, the method of evaluation of component composition of natural gas is based on the decomposition of Raman spectrum into spectra of the individual components is described. To implementing of this method the spectral ranges 250-2500 cm-1 and 3600-3700 cm-1 were selected. The Raman spectra of the main components of natural gas are presented. Results of Raman gas analyzer approbation on a real natural gas sample are presented. A comparison of the experimental results obtained with the results of chromatographic analysis demonstrates their good agreement. It is experimentally established that the given Raman gas analyzer can reliably determine the content of all molecular natural gas components whose content exceeds 0.005% for 100 s.
