Evaluating fugitive emissions sensing technologies (22.RP1.0146)

Methane emission is the second largest portion of greenhouse gas emissions. During natural gas production and processing, of which methane is the main component, fugitive emissions, venting and incomplete combustion have been issues. Various measurement techniques have been tested on-site to monitor this problem, however, those results were deviating from each other. Therefore, it is necessary to understand the source of the gap and evaluate current methane emission sensing technologies.

This project will be implementing a commercial methane sensor (development kit, Bohr Limited) to test with nominated compositions of gas mixtures. The methane measurement will be followed by an uncertainty analysis of measurements and compared to those from well-established lab apparatus. The outcomes of this project will indicate a current limitation of methane sensing in the presence of a specific gas component, so it will also give guidance regarding the optimal installation point in a certain process unit, depending on expected working fluids. A cloud-based platform will be tested for remote data acquisition and visualisation.
