Abstract:

By using the independently developed high-temperature/high-pressure reactor,CO2 water solubility has been tested under different temperatures,pressures and salinities. The results show that the water solubility of CO2 increases with pressure under a certain temperature, while it declines with the increase of temperature under a certain pressure. However, when temperature is above 100℃ and pressure is around 22 MPa,the solubility is prone to decrease with increasing temperature under a low pressure (less than 22 MPa) and the solubility is prone to slightly increase with increasing temperature under a high pressure(greater than 22 MPa). Besides, under a certain temperature and pressure,CO2 water solubility decreases with the increase of water salinity. On the basis of measured and existing data, a new model has been built to calculate CO2 water solubility precisely by modifying the parameters of PR-HV EOS. In comparison to other models, its accuracy is higher with an average relative error of 2.69%.

Key words: high temperature and high pressure, CO2, solubility, theoretical model
