摘要:
【目的】地下储气库具有大量压缩、过滤、计量等设备设施，阀门、连接件、开口管及法兰等设备密封点处易出现甲烷逸散甚至泄漏，不仅会增加储气库运行风险，甚至还会造成环境污染，但目前国内外尚缺乏地下储气库设备密封点逸散的有效量化方法及准确的逸散速率反演方程。【方法】以某地下储气库为研究对象，对储气库的分离区、计量区、井场以及进出站区等6个区域的2030个设备密封点进行实地测量，分析了甲烷逸散体积分数分布区间以及4类设备6个区域的泄漏概率。基于检测结果，修正了将甲烷逸散体积分数换算为甲烷逸散速率的反演方程，并量化了地下储气库地面设施密封点的逸散量。【结果】通过检测发现该储气库甲烷逸散体积分数高于0.01％的泄漏点约70个，主要分布在进出站区、自用气橇区、分离区，其中连接件、法兰、阀门、开口管占总泄漏点的比例分别为40％、26％、20％、14％。计算得到该储气库设备密封点逸散量约为2.4t/a，其中0.44％的设备密封点贡献了约90％的逸散量。将新修正后的反演方程与EPA（Environmental Protection Agency）反演方程、兰发聪校正反演方程进行对比，发现小口径的连接件与开口管两类设备的计算结果相近；对于阀门、法兰类大口径设备，新修正后的反演方程计算结果更大。【结论】新修正后的反演方程计算结果为设备的甲烷逸散总量，核算结果更加准确。同时，实现了反演方程的本土化，可为中国地下储气库设备密封点逸散总量的量化及地下储气库地面设施甲烷减排措施的制定提供依据。（图5，表5，参25）
Abstract:
[Objective] Underground gas storage involves significant equipment and facilities for compression, filtration, and metering. Methane escape or leakage may occur at the sealing points of valves, connectors, open pipes, flanges, and other equipment, leading to environmental pollution and operational risks. However, a method for quantifying methane escape from these sealing points and an inversion equation for the escape rate are not yet available both domestically and internationally. [Methods] This study took an underground gas storage as the example, with field measurements conducted at sealing points of 2,030 sets of equipment in six areas, including the separation, metering, well site, and inlet and outlet areas. The analysis examined the distribution intervals of methane escape volume fractions and the leakage probabilities for four types of equipment in these six areas. Based on the measurement results, the inversion equation for converting methane escape volume fraction into escape rate was revised to quantify the methane escape from the sealing points of surface equipment for the underground gas storage. [Results] Seventy leakage points with methane escape volume fractions exceeding 0.01％ were identified in the gas storage, primarily located in the inlet and outlet valve group area, gas skid area, and filtering & separation area. The proportions of leakage points at connectors, flanges, valves, and open pipes were 40％, 26％, 20％, and 14％, respectively. The calculated methane escape from the equipment sealing points of the gas storage was approximately 2.4 t/a, with 0.44％ of these points contributing to about 90％ of the escape. The revised inversion equation was compared with those from the Environmental Protection Agency (EPA) and Lan Facong, showing similar calculation results for small-diameter connectors and open pipes, while yielding higher results for large-diameter valves and flanges. [Conclusion] The calculation result of the revised inversion equation represents the total amount of escape from the equipment, providing a more accurate estimate of methane escape. In addition, the localization of inversion equation has been achieved, offering a basis for quantifying the total methane escape from equipment sealing points of underground gas storage in China and informing strategies to reduce methane emissions from surface equipment.
