Problem of high liquid level in the air lift separation tank (very confused)
Thread Content
With all the gas lift operation parameters being normal, the pressure in the third liquid separation tank is decreasing while the liquid level in this tank is rising significantly. I’m not sure what could be causing this Is it related to the steam pressure fluctuations in the reboiler?
It might be related to temperatures of 1 or 2 degrees; check if there are any significant changes. Another factor to consider is whether the flow rate at the 3-degree outlet has increased, and it’s also possible that the amount drawn from the side line has decreased

I’m not sure if there’s a problem with your process pipeline design; we’ve had this issue before.
Check if the three-cooler is leaking

Reply 3# adsl121: There is definitely a strong connection between this and pressure fluctuations in the steam; another factor to consider is whether there is any cross-contamination in the heat exchangers. Could you explain in detail? What does it mean when there is a phenomenon of mutual heat transfer in a heat exchanger?
The reboiler equipment may leak internally, allowing steam to enter the tower.
Numbers 1, 2, and 3 refer to the first, second, and third stage condensers in the acidic water stripping unit of the single-tower pressurized side-stream extraction process; their main function is to separate water at high temperatures and remove sulfur at low temperatures, thereby purifying gaseous ammonia
