Cat® Methane Number Calculator is a brand new app for your mobile phone or tablet to allow quick, convenient calculations of methane number, heating value and other natural gas parameters without needing to use your laptop or complicated software. Standard gas samples are pre-loaded or you may enter your own sample from your job site.

This app allows you to enter the constituents of your gas sample in Mole percentages and calculate the Cat® methane number, heating values, inert ratios, compressibility factor, Stoich A/F ratios, specific gravity and specific heat ration in both English and metric. It is loaded with these standard fuels: Coal Seam, Field Gas, Methane, Low Energy, Natural Gas and Propane. You can save your own custom fuels within the app for future reference.

Cat® Methane Number Calculator is a tool designed to help users determine the methane number of a gaseous fuel blend. The methane number is a crucial indicator of a fuel's resistance to knocking or detonation in gas engines. Knocking can cause significant engine damage and reduce its efficiency. The calculator utilizes the fuel's composition, specifically the percentage of each component gas (like methane, ethane, propane, butane, carbon dioxide, and nitrogen), to estimate the methane number. This number then helps operators and engineers determine if the fuel is suitable for use in their specific gas engine. If the methane number is too low, adjustments to the fuel blend or engine settings might be necessary to prevent knocking. The tool typically includes a database of gas properties and employs thermodynamic calculations to accurately predict the methane number. By providing a reliable methane number estimation, the Cat® Methane Number Calculator enables users to optimize engine performance, extend engine life, and ensure safe and efficient operation with various gaseous fuels.
