Abstract

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 increasing the number of theoretical stages. Adiabatic fractionation is characterized by the least heat consumption. This is explained by the increased internal energy saving in the column.
