Embodiment 1
[0076] Control the temperature at 50°C, weigh 0.01g of surfactant sodium bis(2-ethylhexyl) succinate sulfonate (AOT), dissolve it in a mixed solvent composed of 1g of water and 10g of ethanol, and add it to a visual container , adjust the electromagnetic stirring speed to 100rad / min, and the CO in the gas storage tank 2 Into the visible container, until the pressure in the visible container is 19MPa, the added CO 2 mass, i.e. m 2 -m 3 The value is 85.0g, the volume of the visible container is increased through the intermediate container, and the curve of the system pressure and the resistance value of the photoresistor is recorded as figure 2 As shown, it can be concluded that the cloud point pressure of the system is 10.2MPa, restore the initial state of the visible container, increase the volume of the visible container through the intermediate container again until the pressure reaches 10.2MPa, and a total of 27.2mL of water is discharged from the intermediate container,...
Embodiment 2
[0078] Control the temperature at 50°C, weigh 0.02g of surfactant sodium bis(2-ethylhexyl) succinate sulfonate (AOT), dissolve it in a mixed solvent composed of 1g of water and 10g of ethanol, and add it to a visual container In the process, the electromagnetic stirring speed is adjusted to 200rad / min, and the CO in the gas storage tank is 2 Into the visible container, until the pressure in the visible container is 19MPa, the added CO 2 mass, i.e. m 2 -m 3 The value is 86.2g, the volume of the visible container is increased through the intermediate container, and the curve of the system pressure and the resistance value of the photoresistor is recorded as image 3 As shown, it can be concluded that the cloud point pressure of the system is 13.6MPa, restore the initial state of the visible container, increase the volume of the visible container through the intermediate container again until the pressure reaches 13.6MPa, and a total of 9.0mL of water is discharged from the int...
Embodiment 3
[0080] Control the temperature at 60°C, weigh 0.03g of surfactant sodium bis(2-ethylhexyl)succinate sulfonate (AOT), dissolve it in a mixed solvent composed of 1g of water and 10g of ethanol, and add it to a visual container In the process, the electromagnetic stirring speed is adjusted to 500rad / min, and the CO in the gas storage tank is 2 Into the visible container, until the pressure in the visible container is 19MPa, the added CO 2 mass, i.e. m 2 -m 3The value is 85.2g, the volume of the visible container is increased through the intermediate container, and the curve of the system pressure and the resistance value of the photoresistor is recorded as Figure 4 As shown, it can be concluded that the cloud point pressure of the system is 16.0MPa, restore the initial state of the visible container, increase the volume of the visible container through the intermediate container again until the pressure reaches 16.0MPa, and a total of 0.72mL of water is discharged from the int...
