Questions regarding the azeotrope temperature
Thread Content
In azeotropic distillation, why does the temperature T remain constant during vaporization once an azeotrope is reached at a certain pressure? Is the composition at the top of the azeotrope column the one corresponding to the azeotrope temperature?
Azeotropy lowers the boiling points of each component. Vaporization occurs once the boiling point is reached; vaporization requires heat energy, and a continuous supply of heat is needed to maintain this vaporization process, so that the temperature remains essentially constant. 【This is thermal energy balance】.
If it’s not an azeotropic system, why doesn’t the temperature remain constant? Is it simply because the boiling point of the azeotrope decreases? Thank you
