Stabilizer tower operation
Thread Content
Why does the top temperature rise when the stabilizer column pressure increases?
This shouldn’t happen; generally, when the top temperature is high, the pressure should not be high, unless the cold return temperature is also high or a hot bypass is activated. The pressure is high; check whether the bottom temperature of the separation tower is too low, as this causes the C2 components to reach the stabilization tower. If the bottom temperature of the stabilization tower is too high, the pressure at the top of the tower will be even higher. Perhaps the temperature in the lower sections needs to be increased. Specifically, these parameters need to be considered together. If the temperature at the bottom of the distillation tower is not low, then one should look at the temperature after air cooling or cold reflux cooling, as well as the thermal bypass; it depends on the specific circumstances……
The conditions are too limited; there must be other parameter variations as well
More product rises at the bottom of the tower, causing an increase in pressure and temperature
Saturated vapor pressure – learn about it! Thank you
If the upward pressure is related to high bottom temperature, then the top temperature will also rise
If the feed to the stabilizer is increased and the bottom temperature remains unchanged, the load at the top of the tower increases and the pressure rises; if the top reflux remains unchanged, the temperature rises
Please clarify which of these two parameters changes first: the independent variable or the dependent variable
