Abstract

We have developed correlations for the Henry's constant kH and thevapor-liquid distribution constant KD for 14 solute in H20 and six solutes in D20. The solutes considered are common gases that might be encountered in geochemistor the power industry. Solubility data from the literature were critically assessed and reduced to the appropriat thermodynamic quantities, making use of corrections for nonideality in the vapor and liquid phases as best they could be computed. While the correlations presented here cover the entire range of temperatures from near the freezing point of the solvent to high temperatures approaching its critical point, the main emphasis is on representation of the high-temperature behavior, making use of asymptotic relationships that constrain the behavior of kH and kD near the critical point of the solvent.
