Natural gas hydrates, as a clean and green energy source, are widely distributed in extreme environments near the seabed. They release relatively low concentrations of carbon dioxide dissolved water. Therefore, precise detection changes concentration water is an effective means to accurately characterize distribution natural hydrates. Compared direct absorption spectroscopy near-infrared systems, tunable diode laser spectroscopy-wavelength modulation (TDLAS-WMS) system, which operates...
Methane, as an important component of oil-gas, provides valuable data reference for determining the origin oil-gas through its concentration variations, which is essential identifying new reservoirs. However, methane undergoes continuous changes during drilling processes, with a range variation reaching up to 80 dB or even higher. Therefore, achieving wide-range measurement great significance. We proposed single saturated absorption spectral line (SSLCM) method enhance sensing system. By...
