Effect of carbon dioxide on fuel stability under storage conditions

1. Carbon dioxide, when used as an inert gas medium for filling the free space in tanks and reservoirs, limits the sediment formation, wards off the formation of oxidation products and existent gum, and stabilizes the acid number and cloud point of the fuel. 2. The favorable stabilizing effect of carbon dioxide on fuel oxidation in storage is retained at gas-phase CO2 concentrations down to 60%.
