Fluctuations in the pressure of the stripping tower often lead to unstable feed flow rates
Thread Content
Fluctuations in the pressure of the sulfur-containing wastewater stripping tower often lead to unstable feed flow rates. The PID controller is functioning properly; is it a problem with the tower’s design? How can this be improved?
The feed is pumped in, with a control valve behind it
First, identify the reasons for the unstable pressure, and then think about how to improve it
The pressure is unstable, which is related to the heating system and the condensation system; the cause should be identified first.
I’m not aware of your operating parameters; the pressure fluctuations might be caused by an imbalance in heat within the tower system. Try adjusting the ratio of cold to hot feed to see if that helps. It is also possible that tower pressure fluctuations are caused by phase changes between gas and liquid due to oil present in the sulfur-containing wastewater. Trying to strengthen the oil removal – will it work?
