Chem. Eng. Japan, 13, 130 (1980 A method to estimate the composition of solid condensate from a binary vapor in fractional sublimation accompanied by an entrainer gas is derived, including an overall coefficient for condensation of the individual components. The coefficient was empirically correlated with gas flow rates, surface temperatures of condenser, and condenser dimensions. Good agreement between the estimated and observed compositions of the condensates was obtained for two eutectic-forming organic mixtures and one solid solution organic mixture.
