Abstract: A chemical composition analyzer may be used to optically determine and report chemical compositions associated with natural gases within a gas collection and transmission infrastructure. This analyzer includes a number of optical sensors which may be used to perform spectroscopic spectrographic analysis in order to determine the chemical composition of the natural gas. Additionally other sensors may be used to measure other physical properties associated with the natural gas. These sensors are tied to a data collection system wherein the output of the optical sensors and sensors used to measure the physical properties of the natural gas may be combined and processed in order to determine in a nearly continuous fashion the chemical composition associated with the natural gas at various locations within the gas collection and transmission infrastructure. This real time compositional analysis may be used to determine valuations of the gas or to optimize other processes or equipment configurations.

Abstract: Methods and systems for real time, in situ monitoring of fluids, and particularly the determination of both the energy content and contaminants in a gas or oil transmission facility, are provided. The system may include two separate scanning sources to scan two different, but overlapping, NIR ranges, or may involve two separate scans from a single scanning spectroscopy source. The first scan ranges from approximately 1550 nm up through 1800 nm and a second scan concurrently scans at a high resolution across a band from approximately 1560-1610 nm, the wavelength of interest for hydrogen sulfide (though similar scans are contemplated in alternative wavelength ranges for alternative contaminants). The second scan may provide very narrow (0.005 nm) step resolution over just the wavelength of interest for the contaminant and may scan at a substantially higher power level.
