Table 2 Experimental conditions for CO2 displacement in CH4 tests.
From: Effect of CO2 injection pressure on enhanced coal seam gas extraction
CO2 injection pressure/MPa | CH4 adsorption volume/L | Original coal seam gas content /ml/g | CH4 saturation pressure (MPa) |
|---|---|---|---|
0.6 | 117.285 | 7.187 | 0.448 |
0.8 | 119.192 | 7.304 | 0.435 |
1.0 | 119.908 | 7.347 | 0.442 |
