At this paper approaches and results of computational and experimental studies in support of mass exchangers design with solid oxygen source is described. The performance of mass exchangers with the in-built pump and pneumatic type (discrete operating principle) is studied. Experimental studies of the performance mass exchangers was carried on a facility with a non-isothermal circulating coolant Pb-Bi (SSC RF-IPPE). The calculations were performed using empirical temperature dependences of oxygen solubility and dissolution rate coefficients of lead oxide in the Pb-Bi. Dissolution of lead oxide in the mass exchange apparatus was seen as a process of physical dissolution of the solid. The studies obtained dependence thermodynamic activity of oxygen at the outlet of the mass exchanger and its performance on the regime. It is shown that the calculation results are in good agreement with experimental data. Executed work confirms the possibility of estimation performance mass-exchangers, which is extremely important in creating mass-exchangers for a particular object, for example, the nuclear power plant, in order to select an optimal design and parameters of its work.
