Can excessive water in the reflux tank lead to an uncontrolled pressure in it? Why
Cooling reflux is required at the top of the stabilizer; liquefied gas carrying water to the top of the tower causes fluctuations in the pressure there
The heat absorption of water is different from that of liquefied gas, which directly affects the top temperature of the tower; the top temperature in turn has a direct impact on the pressure at the top of the tower.
The liquefied petroleum gas reflux tank contains water because the deethanized gasoline flowing in it has water; the deethanized oil contains water due to a high oil-water interface level in the oil-gas separator at the outlet of the compressor upstream, or due to malfunctions of that interface level. The heat absorption rates of liquefied gas and water are different; the presence of water can cause pressure fluctuations in the liquefied gas return tank, affecting the operation of the stabilization system.
Stabilizer operation: when liquefied gas contains water, changes in the cooling load of the stabilizer affect the pressure
