The report details the composition change of LNG as it weathers in a vehicle size tank. The composition methane number and stoichiometric air-fuel ratios each change with composition. The results show that the factor controlling weathering is the tank heat leak rate. Weathering occurs at a constant rate when plotted against tank volume, that is composition change is primarily a function of tank volume and the percentage of initial fill boiled off. Heat leak defines the rate at which weathering occurs.
