distillation tower
Thread Content
When steam is suddenly added to a distillation tower, why does the temperature at the top of the tower rise while the pressure decreases?
Is it related to the gas-liquid equilibrium at this point?
Has the reflux pump at the top of your tower increased its capacity? The increased cold cycle leads to rapid cooling and phase change in the gas phase, resulting in low pressure!
The heavy components are vaporized in large quantities; since these heavy components condense easily, the tower pressure decreases.
The temperature rises because of the increased content of heavy components, while the pressure drops due to the decreased partial pressure of light components
