Study on the improved method for natural gas analytical system performance evaluation

Abstract With the advancement of natural gas energy measurement methods by domestic governments, enterprises, and users, GB/T 28766-2018 Performance Evaluation of Natural Gas Analysis Systems has received increasing attention and widespread application since its release and implementation in 2018. However, most of the gas chromatography used domestically employs a single-point calibration function for sample analysis and cannot implant true regression functions, which significantly limits the application of the standard. Based on the standard method and the current state of the domestic natural gas industry, this paper proposes an improvement measure for the standard method and validates the improved method through actual measurements. The performance evaluation data from nine chromatography demonstrate that the proposed method can effectively identify equipment with issues.
