Coking absorption tower flooding
Thread Content
Since the opening ratio of the absorption tower was increased, it often experiences flooding; how should it be operated?
Increase pressure, boost mid-section reflux and absorption dose
If possible, check the condition of the trays, as it is unlikely that salts will accumulate on the trays of the absorption tower
Isn’t it necessary to calculate the corresponding backflow rate based on the porosity? Otherwise, if the vapor phase volume becomes too large, it will definitely cause problems in the tower.
Increase the backflow rate, because when the porosity increases, more gas rises upward; this creates an imbalance between the gas and liquid phases, which in turn leads to tower flooding
It is because when the porosity is increased, the corresponding backflow rate also has to increase; otherwise, the gas phase cannot be held back.
