Experimental determination of the solubilities of dissolver off-gas constituents in a Kr-85 recovery solvent (CCl/sub 2/F/sub 2/). Final report

The experimental determination of the solubility of the major off-gas constituent-Nitrogen was performed with a new solubility measurement apparatus. The new apparatus was designed, built and tested; an algorithm for thermodynamic consistency testing of P-T-x-y data for solubility systems was developed, and thermodynamically consistent Nitrogen-R-12 solubility data were taken. The Henry's Law constant for the Nitrogen-R-12 system can be represented by the equation ln H/sub N/sub 2/-R-12/ (atm) = 0.44 + 1.0708 lnT (/sup 0/K). The solubility data extend the range of known equilibrium data into a region where process equipment operate and are consistent with both other data at lower temperatures by other researchers and with regular solution theory.
