pH prediction in concentrated aqueous solutions under high pressure of acid gases and high temperature
چکیده انگلیسی
An extended model for pH prediction in oil and gas environments has been developed. Accurate pH calculations for high pressure and high temperature applications depends mainly on CO2 and H2S partial pressures, the ionic strength, the chemical composition of the solution, and the temperature. Accounting for the non-ideal behaviors of liquid and gas phases allows pH calculations up to 200 °C, 2000 bar total pressure, and ionic strengths up to 5 mol L−1. The results are consistent with experimental measurements and with other models reported in the literature.
