“…The Raman spectroscopy could be an alternative solution to those mentioned above. Raman spectroscopy has a wide scope of application in many fields of the oil and gas industry [15][16][17][18][19][20][21]. There is the possibility to apply this technology to oil and refinery products research, but in terms of research in natural gas engineering, analysis of natural gas composition is challenging from the Raman spectroscopy application point of view.…”

“…Pressure growth causes also a shift of a characteristic band of a given vibration. Performing a similar analysis for a set of samples with different molar fractions allows one to create a intelligent algorithm which enable characterization of reservoir fluid through Raman spectra comparison [17,20,26,[29][30][31][32][33]. This knowledge is fundamental for further reservoir fluid analysis.…”

“…Excellent agreement with reference gas chromatography measurements was found. In recent years, Buldakov et al [60,61] developed a Raman analyzer for natural gas characterization as well. They obtained similar sensitivity (~0.01%) using a multi-pass arrangement and a 2-W laser (532 nm).…”

Most commercial gaseous and liquid fuels are mixtures of multiple chemical compounds. In recent years, these mixtures became even more complicated when the suppliers started to admix biofuels into the petrochemical basic fuels. As the properties of such mixtures can vary with composition, there is a need for reliable analytical technologies in order to ensure stable operation of devices such as internal combustion engines and gas turbines. Vibrational spectroscopic methods have proved their suitability for fuel characterization. Moreover, they have the potential to overcome existing limitations of established technologies, because they are fast and accurate, and they do not require sampling; hence they can be deployed as inline sensors. This article reviews the recent advances of vibrational spectroscopy in terms of infrared absorption (IR) and Raman spectroscopy in the context of fuel characterization. The focus of the paper lies on gaseous and liquid fuels, which are dominant in the transportation sector and in the distributed generation of power. On top of an introduction to the physical principles and review of the literature, the techniques are critically discussed and compared with each other.

“…Those techniques usually give a performance increase of several orders of magnitude, but unfortunately they are not applicable for noninvasive sensing through the material of a container. Among already developed Raman gas sensors based on an optical cell containing the gas under analysis and a dispersive spectrometer, we note the applications to fuels and gas composition analysis [11][12][13][14][15]. Data from the literature [16] can provide an interesting overview about the ultimate sensitivity performance which can be reached with state-of-the-art components and a single-pass optical cell coupled with a dispersive spectrometer; for both nitrogen and oxygen, this is in the hundreds of ppm range.…”

A non-dispersive approach for a Raman gas sensor

Although Raman spectroscopy is widely used on solids and liquids, its application on gaseous samples is far less commonplace due to technical issues related to dealing with very weak signals over a strong background. A demonstration of a possible approach for a simple, noninvasive Raman-based gas detector is presented and evaluated. This setup is meant to perform nitrogen and oxygen gas concentration measurements through Raman scattering working with optical filters instead of the traditional spectrograph and a lighting-grade 532 nm diode-pumped solid state laser as the pumping source. An industrial-grade CMOS camera is used as the detector, taking full advantage of the low noise and spatial resolution of this device. The system has been tested for both oxygen and nitrogen in a gas flow cell. Nitrogen measurement in a glass vial is reported in order to demonstrate and show some of the advantages that could be obtained with the use of an imaging detector instead of a single pixel one. The reported measurements show that even without using a dispersion spectrometer, this approach enables an indicative, noninvasive gas detection through glass vials with significant rejection of the elastic scattering contribution.
