Heat regeneration tower top reflux pump
Thread Content
The reflux pump at the top of the purification thermal regeneration tower keeps suffering from cavitation, and the cause cannot be identified. Does anyone have any good solutions?
Would it help to raise the liquid level in the reflux tank a bit?
It may be that H2S gas present in the liquid vaporizes upon entering the pump, thereby causing cavitation; a pipeline can be installed from the pump to the inlet of the reflux tank on the acidic gas/methanol pipeline. We have set up this pipeline; I’m a new trainee, so my opinions are for reference only :)
