Otherwise, it could lead to a sequential shutdown of the nitrogen stripping process. Answer: If the liquid level at the bottom of the hydrogen sulfide concentration tower is higher than that of the nitrogen stripping pipeline, liquid slugging will occur. This not only can damage the equipment but also causes the nitrogen stream carrying liquid to impact the tray plates, potentially leading to deformation or even destruction of those trays. Furthermore, when parked, the liquid level at the bottom of the hydrogen sulfide concentration tower is too high, allowing methanol to easily flow back along the stripping nitrogen pipeline. Therefore, the liquid level at the bottom of the hydrogen sulfide concentration tower should not be too high; otherwise, it will trigger a sequential shutdown of the gas stripping and nitrogen production processes. The liquid level should be kept as low as possible during shutdown.

If the liquid level at the bottom of the hydrogen sulfide concentration tower is higher than that in the nitrogen stripping line, a liquid slugging phenomenon will occur. This not only risks damaging the equipment, but also causes the nitrogen stream carrying liquid to impact the tray plates, potentially leading to their deformation or even displacement. Furthermore, when parked, the liquid level at the bottom of the hydrogen sulfide concentration tower is too high, allowing methanol to easily flow back along the stripping nitrogen pipeline. Therefore, the liquid level at the bottom of the hydrogen sulfide concentration tower should not be too high; otherwise it will lead to a sequential shutdown of the gas stripping process. When shutting down the system, the liquid level should be kept as low as possible

When the liquid level is higher than that of the gas nitrogen pipeline, liquid slugging can occur, which may damage the equipment; nitrogen gas containing liquid can impact the tray plates and cause deformation and damage. During shutdown, excess methanol can flow back into the nitrogen pipeline.
If the liquid level at the bottom of the H2S concentration tower is higher than that in the stripping line, liquid slugging will occur. This not only can damage the equipment easily but also causes the nitrogen used for stripping to carry liquid with it, which can lead to deformation or even displacement of the tower trays. Furthermore, when parking, the liquid level at the bottom of the H2S concentration tower is too high, allowing methanol to easily flow back through the gas lift pipeline. Therefore, when parking, it is essential to keep the liquid level at the bottom of the H2S concentration tower as low as possible.
