Landfill gas (LFG), which is primarily composed of CH4, CO2, and N2, is produced from the anaerobic digestion of organic materials. To investigate the feasibility of the storage and transportation of LFG via the formation of hydrate, we observed the phase equilibrium behavior of CO2–CH4–N2 mixture h...
