Increase the operating pressure of the distillation tower
Thread Content
From a simulation perspective, if the operating pressure of the distillation column is increased, how should the heat load at the top of the column change?
The tower top temperature decreases, and the load reduces.
Reply to 2# wsm1988: Could you explain the reason?
As pressure increases, the saturation temperature rises, so the top temperature of the tower increases. As pressure increases, the latent heat of condensation decreases, so the heat load decreases. If deep cooling is required, things get a bit more complicated.
As pressure increases, the latent heat of condensation decreases. How can this be explained? Are there any formulas or resources I can consult?
Reply to 4# emirateyi: How to explain latent heat of condensation? If the pressure at the top of the tower is high, the temperature must also be high; therefore, the heat load at the top of the tower should increase, right?
