Reason why the pressure at the top of the atmospheric pressure tower is close to the pressure in the reflux tank
Thread Content
There is usually a pressure difference; why have the two pressures become close recently?
Has the pressure difference decreased? It turns out that the temperature is relatively low, which results in an excellent cooling effect; as a result, the saturated vapor pressure decreases after cooling ； As the temperature rises, the cooling effect becomes slightly weaker, resulting in a higher saturated vapor pressure! To determine whether it’s correct or not, you can check the temperature after cooling!
But when I use air cooling, both the tower pressure and the tank pressure drop, and the pressure ends up being below the specified control values
But when I use air cooling, the tower pressure also drops, falling below the specified control values
It shouldn’t have much of an impact, right? ? Is there a control valve at the gas outlet on the top of the reflux tank?
Yes, but the pressure in the tank should not be higher than the pressure in the tower under normal conditions; moreover, it’s not clear whether this could cause backflow
