.... This involves introducing a complex natural gas fluid blend and incrementally increasing the levels of hydrogen within the mix. By doing so, we aim to observe and quantify the deviations in results as hydrogen concentrations vary. This model not only serves as a theoretical exploration but also sets...

The study was initiated after observing quite large deviations between gas temperatures measured by a pipeline inspection tool (PIG) and simulated gas temperature profiles for two different pipelines in operation. In addition, noticeable deviations were observed among the different simulation...
