Properties of amine solutions for desulfurization
Thread Content
The amine solution used for desulfurization is alkaline in nature. If liquefied gas carries this amine solution into the pre-alkaline washing tank, will it affect the concentration of the alkaline solution?
Although diethanolamine in the lean ammonia solution has two hydroxyl groups, its degree of ionization is lower than that of the alkaline solution; its basicity is much lower as well. Over time, the presence of this substance can have a diluting effect. There are also other complex factors at play, such as foaming in the lean solution, water vapor, and other components in liquefied gas reacting with the alkaline solution. Over time, the concentration of the alkaline solution will definitely decrease
Won’t a small amount of liquid going through have any effect?
A small amount is part of a process of quantitative change; it has not yet reached a qualitative change!
If alkali solution gets into the desulfurizer, will it affect the quality of the desulfurizer?
