Empirical model for calculating vapor-liquid equilibrium and associated phase enthalpy for the CO2--O2--Kr--Xe system for application to the KALC process

An empirical model is presented for vapor-liquid equilibria and enthalpy for the CO2-O2 system. In the model, krypton and xenon in very low concentrations are combined with the CO2-O2 system, thereby representing the total system of primary interest in the High-Temperature Gas-Cooled Reactor program for removing krypton from off-gas generated during the reprocessing of spent fuel. Selected properties of the individual and combined components being considered are presented in the form of tables and empirical equations
