Abstract

We compared the heat consumption in the separation of binary mixtures by distillation (single evaporation) and rectification for mixtures with different levels of separation by distillation. The advantage of rectification over distillation was shown. The direct dependence of the internal energy saving in rectification on the minimum reflux ratio was established.
