High pressure difference in the amine solution regeneration tower, leading to tower flooding
Thread Content
If the steam level rises slightly, the pressure difference in the regeneration tower increases, leading to a surge in pressure within the tower – is this related to high levels of hydrogen sulfide in the feedstock?
In simple terms: 1. The presence of thermostable salts; 2. The presence of impurities. Solutions: 1. You need to check whether thermostable salts are present in the solvent, and this is a rather complicated task. Using defoamers is also a temporary fix. 2. As for impurities, it is necessary to clean the heat exchanger and the filters at the inlet of the pumps promptly, and this cleaning process must be repeated multiple times.
It is estimated that the heat-stable salt content is too high; the amine solution is a system prone to foaming. Using floating valve trays inherently involves bubbling, which leads to flooding of the tower. Add me on WeChat.
I’ll provide you with a free test for thermostable salts and impurities; message me
It’s foaming. With thermally stable salts, high foaming usually doesn’t occur to such an extent; we should focus on impurities – does the lean solution have an activated carbon filter, and has the activated carbon become fragmented?
Sometimes steam fluctuations are fine, but other times even slight fluctuations are not acceptable

Putting aside everything else for now, change the background color of this DCS; otherwise, it’s too difficult for the operators.
Let’s go into more detail about the specifics. We’ve encountered this situation before; I’m not sure if it’s the same for you guys
