Abstract

The temperature dependence of separation factor has been investigated for fine purification of ammonia in batch packed distillation columns. For a number of binary ammonia-impurity systems, the separation factor as a function of temperature between the normal boiling point and the critical temperature passes through a maximum. The position of this maximum depends on the separation coefficient of the binary mixture.
