According to the profile temperature shown in Fig. 2.a, the inlet wine temperature (experimental point
corresponding to the second stage) should be around 340-344 K in order to keep the column temperature
profile and to save energy consumption in the column reboiler. The lower temperatures obtained at the
top of the degasifying column are related with the high CO2 concentration there (see Fig. 2.b); in addition,
due to that the ethanol composition does not change drastically at the bottom of the column, the
temperature profile remains almost constant in this section
