 This research paper examined the development of a mobile carbon dioxide methane measurement system for use in industrial plants. It also assessed the accuracy of this system by comparing its results with those from a simulation model. The authors found that the system could accurately measure the concentration of both gases at different locations within the plants, and that it could be used to estimate the overall emissions from these plants.
