The current research status of leak-age detection and repair(LDAR)technology in foreign countries from both the policy and technical perspec-tives,the similarities and differences in the technical guidance documents are pointed out,and the cost-effec-tiveness of conducting LDAR is analyzed.By analyzing relevant domestic policies and standards,the back-ground of LDAR implementation in urban gas plants and stations in China,and the specific process of LDAR implementation,the application of LDAR in urban gas plants and stations is studied.It is suggested to study the methane emission calculation formula conforming to Chinese localization characteristics.It is proposed that urban gas enterprises should comprehensively carry out LDAR and implement methane emission reduction measures in a planned manner to help complete the"dual carbon"strategic task.
