The stripping steam pressure in the stripper decreases
Thread Content
As the title suggests, a decrease in the stripping steam pressure at the bottom of the stripper has what effects on the separation efficiency of the stripper and its operation? Thank you all
Since the steam pressure has decreased, can the flow rate be increased appropriately? In this way, the input energy and gas do not decrease, and the stripping effect can still be satisfied
Well, it’s one method, but it might reduce the processing capacity of the tower, right?
The steam pressure has decreased; after correction of the value shown on the instrument, it remains the same as when the pressure was high, so the stripping efficiency does not decrease.
With all other conditions unchanged, if the steam pressure decreases, the flow rate will drop as well; the enthalpy of the steam will decrease, and consequently the heating effect will be reduced. The observed phenomenon is a decrease in the temperature at the bottom of the tower, along with a reduced stripping efficiency. If it is pressure fluctuation, it is best to monitor tower pressure and temperature. If the steam pressure remains stable and it is necessary to increase the steam flow rate, then this flow rate cannot be determined based on empirical values; instead, adjustments must be made by referring to the tower pressure and temperature.
It mainly depends on the stripping temperature; if the temperature is too low, it’s not good as water will be carried along!
