Abstract

This paper studies methane emissions reduction at natural gas transmission systems. A literature survey on the topic is presented along with some characteristic case studies. Such case studies reveal that a significant reduction of methane emissions at gas transmission systems may be achieved with application of best practices, resulting in a large impact on decarbonization and environmental protection efforts. At a characteristic case study, the maintenance plan optimization of the scraper traps along a gas transmission network reduced methane emissions by 90%. Quantification of methane emissions reduction at the presented case studies may serve as quick reference for similar applications. The analysis aims to contribute to better understanding of methane emissions sources and the adoption of emissions reduction measures at gas transmission systems.
