On-line monitoring of odorant in natural gas mixtures of different composition by the infrared absorption spectroscopy method

摘要

This paper reports on the results of research aimed at solving the problem of on-line monitoring of odorant in natural gas mixtures in order to make the odorization process effective and ensure the safety of main gas pipeline exploitation. Our results show that using the infrared absorption spectroscopy method is promising for this purpose. Using radiation sources operating in the spectral range 6-15 mu m allows us to obtain an odorant detection sensitivity of approximately 5 ppm in gas mixtures of different composition.
