DISTRIBUTION OF SOLUTES BETWEEN COEXISTING STEAM AND WATER

For a thorough description of aqueous systems with coexisting liquid-vapor phases, it is necessary to have a means of describing the concentration of solutes in the two-fluid phases over a wide temperature range. A general procedure is presented which allows the description of the distribution ratio of solutes at infinite dilution (K(D)) between water and steam over all the range of coexistence of the two-fluid phases. The procedure has been employed for many different solutes, e.g., nonreactive gases, reactive gases, nonionic, and ionic solutes. For the gaseous solutes a formulation is given which allows the calculation of K(D) over the complete temperature range with good precision.
