Performance Evaluation of Online Analysis System for Natural Gas Energy Metering
Gas chromatograph online analysis system is the key equipment for energy measurement of natural gas,its accuracy and adaptability need to be evaluated.Taking a domestic online analysis system as the research object,experiments of technical indicators such as effectiveness,separation degree,repeatability and consistency of the test gas are carried out under the requirements of the standard,and the stability and difference experiments of the gas are carried out to be measured on site,and the feasibility of the analysis system for energy measurement is confirmed.The results shows that the separation degrees of methane and nitrogen,n-butane and isobutane in all the test gases meet the standards requirements,and the relative deviations of qualitative and quantitative repeatability of components are smaller than the standard requirements.The energy measurement results are not significantly different from those of foreign gas chromatographs.The research results can provide practical reference for the localization of online analysis system.
