Abstract: This study presents a computational tool for analyzing gas mixtures resulting from the integration of biomethane and hydrogen into natural gas networks. It calculates key properties, such as relative density, higher heating value and Wobbe index, based on composition, temperature and pressure, using the van der Waals equation to model real gas behavior. The tool also offers interactive 3D visualizations to explore how these properties vary under different conditions. With prediction errors below 0.5% at 20 atm, it provides a reliable basis for assessing technical feasibility, regulatory compliance and energy efficiency in the integration of alternative gases into existing networks.
