Function of the control valve on the overhead gas from the catalytic cracking separation tower
Our desorption tower does not have a control valve for the gas coming from the top of the tower; this gas goes directly to the air cooler and then to the compressor rich gas water cooler. :lol
It can be controlled when necessary; it has no effect during normal operation.
Yes, in the past it didn’t have that; even when we went out to study*, there was no such control valve. Ours was designed by Changling
In my opinion, installing a control valve allows for manual control of the pressure at the top of the distillation column; this enables rapid pressure control in case of an accident, thus maintaining normal operation of the three columns

It enables better control of tower pressure and improves the stability of the tower.
Currently, in the unit, the transfer of oil from the stripping tower to the stabilizing tower is carried out under self-pressure. In the absence of pressure control valves, when the pressure in the reabsorption tower drops, the pressure in the stripping tower also drops. This can affect the efficiency of the stripping process; in severe cases, it prevents the oil from the stripping tower from reaching the stabilizing tower under self-pressure, resulting in significant fluctuations in operations. So, you get it now, right?
