基于包袋法的甲烷泄漏逸散排放监测核算方法准确性研究
Research on the Accuracy of Monitoring and Accounting Method of Methane Leakage Emission Based on Bag Method
摘要
Abstract
Aiming at the problems of imprecision and low accuracy in the calculation of default methane e-mission factors of equipment components,a bag-based monitoring and accounting model for methane leakage and escaping emissions of equipment components was constructed to study and analyze the impact of environ-mental temperature and measurement errors of environmental temperature,gas production flow,methane con-centration and atmospheric pressure on the accuracy of the model,and the accuracy of the monitoring and ac-counting method was verified by experiments.The results showed that the input parameter measurement error was controllable and the output error was acceptable in the range of-10～30℃.Under different experimental conditions,the absolute error of methane leakage emission monitoring and accounting was 18.4%at the maxi-mum,0.1%at the minimum,and 9.1%on average,which can meet the requirements of on-site monitoring and accounting in the range of the volume concentration of methane leakage of equipment components(0～100)%.The absolute errors of the experimental results were randomly distributed,but there were many negative errors.Ef-fective measures should be taken to reduce the systematic errors of the experimental verification platform.关键词
