What is the relationship between tower pressure and liquid level during hot oil transfer?
Thread Content
At the beginning of operation, when hot distillate oil is transferred, the liquid level in the tower rises – so how can the pressure at the top of the tower decrease? Moreover, the liquid level changes significantly, fluctuating up and down, making it difficult to control.
It wasn’t described clearly. What is the oil transportation process? What kind of fractionation towers are there?
The process of transporting hot oil involves establishing a circulation at the bottoms of each distillation column, with a heater being used at those bottoms to raise the temperature of the hot oil. Fractionation tower of anthracene hydrogenation unit
The load on the top cooler increases, the column pressure drops, and the liquid level at the bottom of the column rises.
If the load on the top cooler is high, shouldn’t that mean that the light components rise within the tower, causing the top pressure to increase and the liquid level at the bottom to decrease? Please offer your guidance, master. Thank you
