With the change of global energy consumption structure, natural gas as a clean low-carbon energy has been promoted and used by more and more countries.
However, with the aging of natural gas pipelines and equipment, natural gas leakage has become a major problem in the energy industry. Once a natural gas leak occurs, it not only wastes natural gas, but also poses a serious threat to safety, public health and air quality.
Therefore, the timely and accurate detection of natural gas leaks, the specific location of the leaks and the leaks, and the prevention of hidden dangers are very important.
Although several natural gas leakage monitoring technologies have emerged, each has its own drawbacks. One is a dedicated camera that can only sense methane in a short distance. This monitoring process is labor-intensive and does not fully reflect the large-scale methane leakage. The other is the display of a number of large-area leaks within a few kilometers from aerial or satellite images, but it does not show the details of the leak.
Recently, an independent research team in Boulder, Colorado, announced two new technologies that use laser frequency combs to detect natural gas leaks. This technology can not only provide real-time gas concentration sensitivity indicators but also determine the location of leaks.
It is reported that the ultimate goal of the team is to establish a monitoring system in which multiple laser sources can be strategically deployed around a natural gas production site. All laser sources point to the mid-infrared spectrometer at the center of the site. When the system's detection data is combined with the atmospheric model, it can provide real-time gas concentration sensitive indicators based on the double-frequency comb-like absorption spectrum generated when the leaked gas passes through the beam path. At the same time, the leakage characteristics can be determined based on the distribution characteristics of the system. position.
The rapid development of the global natural gas industry has also further promoted the development of the natural gas leakage monitoring market. According to relevant data, the global oil and gas leak detection market is expected to reach US$3.38 billion in 2022, with a CAGR of 2016-2022. It is 6.9%.
With the development of the natural gas leakage monitoring market, the development of natural gas leakage monitoring technology will be further promoted to safeguard the safe operation of the natural gas industry.
