Separation of Hydrogen Isotopes by Multicomponent Distillation
Separation of liquefied gas mixtures by fractional distillation may be accomplished in either a continuous or batch operation. Continuous distillation is preferred for large feed mixtures of nearly constant compositions. On the other hand, the batch method is more suitable for separating relatively small feed mixtures of widely varying compositions. Steady state conditions with regard to temperature, pressure, and composition characterize the continuous system while in a batch system all of these parameters change continuously with time. As an extension of earlier work1 on the separation of hydrogen-deuterium mixtures, this paper deals with the batch separation of a mixture containing all six possible isotopic modifications of hydrogen.
