Formulas for calculating internal energy saving in a fractionating column without preheating and with heating to boiling point of the initial mixture are given. Formulas are derived for calculating internal energy saving in various schemes of heating of the initial mixture by vapor stream in the rectifying section of the column. The optimum scheme ...

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 wa...

The heat consumptions during fractionation of a binary mixture using different versions of heat supply to the column were compared. The standard version of adiabatic fractionation was compared with real versions that approximate it to reversible fractionation by using distributive heat supply (and removal) along the height of the column and increas...
