How does the tower temperature change when the pressure at the top of the distillation tower changes?
Thread Content
It refers to the change in temperature when the tower pressure changes, with all other conditions (such as steam volume, reflux, etc.) remaining unchanged We usually say that pressure increases temperature and boiling point (due to the increase in boiling point), but under pressure the components in a vaporized substance become lighter, while temperature reflects the properties of the material components; therefore, the temperature should decrease!

Generally, when the top pressure of the tower decreases, reboiling is increased; when the top pressure rises, reboiling is reduced. Of course, there are many control methods available, and the most effective one should be chosen.
