| Abstract;"Injection of liquid CO2 in hydrate layers of natural gas is a promising technique to recover CH4 simultaneously segregating CO2 from the biosphere. This work examined the rate of the conversion of CH4-hydrate immersed in liquid CO2 to CO2-hydrate in a temperature range of 274-281K and the pressure range of 4-10 MPa. The recovery rate as the temperature increased, it decreased as the total pressure increased. At 10 MPa,281K, about 17% of the methane by CO2 was recovered after 300 hours and continues for long time. The configuration of the system should be investigated in a feasibility study, including the recovery system for methane [disposal of CO2, methane hydrate, CO2 hydrate,displacement]" (author abst.) |
