Abstract

A method was invented to convert methane concentration at the surfaces emitting fugitive methane into methane emission rate. This method requires surface scan of methane concentration using handled devices such as flame ionization detector (FID) to measure the fugitive methane near-surface concentration based on which, the methane emission rate can be calculated using a correlation expressed in a mathematical form.
