Methodology of methane emission accounting in petrochemical and chemical industries of China

Abstract

Abstract Nowadays, the whole greenhouse effect is becoming more and more serious. It is the common mission of mankind to curb global warming. As the world’s second largest greenhouse gas (GHG), the warming potential caused by methane (CH4) is not negligible, so it is imperative to calculate and reduce its emissions. For the lack of CH4 accounting methodology in China’s petrochemical and chemical industries, this paper proposes a CH4 accounting methodology based on the enterprise’s accounting boundary. Emission sources include CH4 emissions from fuel combustion., CH4 emissions from flare gas combustion, CH4 emissions from escape, CH4 emissions from anaerobic treatment of sewage, CH4 emissions from accidental venting. The research results are an important exploration for the accurate measurement of CH4 emissions from enterprises in China’s petrochemical and chemical industries, and also complement the research on China’s greenhouse gas accounting methodology.
