A Comprehensive Evaluation of Empirical Correlations for Computing the Solubility of Co2 in Water
نویسندگان
چکیده
A new correlation to estimate the solubility of carbon dioxide in water for the temperature interval of geothermal interest (from 25°C to 350°C) is proposed. This equation was derived from a comprehensive statistical analysis applied to an updated thermodynamical database containing experimental solubility data reported in the literature. In addition, it is also presented a useful equation to quantify the propagated error generated through the use of the new polynomial correlation developed. These equations will be implemented into a new geothermal wellbore simulator (under construction) for modelling the vertical-ascendant two-phase flow in geothermal wells.

Solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. Also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. Therefore,...
