In this era of rapid technological advancement, natural gas—a clean, efficient, and widely used energy source—has permeated every corner of our lives. Yet, while offering convenience and efficiency, it also harbors significant safety risks. A gas pipeline leak can trigger severe accidents like fires and explosions, causing immense loss of life and property while inflicting irreversible environmental damage. Therefore, ensuring gas safety throughout production, transportation, and usage has become an urgent and critical challenge for society.

　　Among the various components of natural gas, tetrahydrothiophene (THT) serves as a common odorizer widely added to gas to enable timely detection of leaks. THT possesses a distinctive, pungent odor detectable even at extremely low concentrations, providing a crucial clue for early leak detection and prompt response. However, the concentration of tetrahydrothiophene is not constant; it is influenced by various factors such as gas production processes, storage conditions, transportation distances, and ambient temperatures. If the concentration is too low, it may fail to trigger timely alerts during leaks, leading to undetected safety hazards. Conversely, excessively high concentrations can irritate the respiratory tract and eyes, posing risks to human health.

　　As a major player in the energy sector, Sichuan Huayou Group Co., Ltd. deeply understands the critical importance of gas safety for corporate development and social stability. Throughout its long-term operations, the company has consistently prioritized safety, continuously exploring and innovating effective methods for gas safety management. With the continuous advancement of technology, traditional gas pipeline monitoring methods have become inadequate to meet the demands of modern gas safety management.
