Carbonized ammonia water carbon dioxide removal methods and processes
Thread Content
What are the existing mature processes for removing carbon dioxide using ammonium carbamate, and which of them are the most reliable? Here, the concentration of ammonia is 10%, and the carbon dioxide concentration is also around 10%. Are there any good methods to remove the carbon dioxide dissolved in the ammonia? Seeking advice.
Do we have to part? Is this a urea factory? Ammonia and carbon can be separated; if the amount is small, there’s no need to go through the process, as separation is too troublesome.
The quantity is large; there is no source for the ammonia solution. If needed, it can be shared.
Which factory produces the ammonia? In the case of a fertilizer plant, after ammonia and carbon are concentrated, they can be fed back into the fertilizer production equipment.
It’s not from a fertilizer plant; it’s ammonia produced by chemical enterprises through ammonia distillation.
The treatment technology for ammonia solution is not an issue; the key factor is whether this ammonia solution contains other impurities, as that determines its subsequent uses
Can’t simple desulfurization and denitration be used? The requirements for ammonia water should be quite low in that case.
Ammonia-based desulfurization for boilers should not present many problems, but caution is needed when using it for SCR denitration, as catalysts are expensive and delicate； It’s hard to say for sure that it will work for SNCR denitration; it’s unclear what impact unknown components may have on the boiler. Moreover, many systems use SCR as well. Even if these factors are taken into account, the equipment designed to use ammonia is usually made of carbon steel, and ammonia carbonate is highly corrosive, requiring materials such as 304L or even 316L ； If the original design used urea, it should work
