After adding calcium hydroxide emulsion in the deammoniation process of soda ash production, is it necessary to let it stand for sedimentation? Or should it go directly into the ammonia stripper?

In soda ash production, after adding calcium hydroxide emulsion during the deamination process, is it necessary to let it stand for sedimentation? Or should it go directly into the ammonia stripper? What mainly affects scaling? Which hero can offer some guidance?
The OP has never worked at the soda ash plant? Ammonia steaming with lime milk does not require static sedimentation. The OP can refer to books such as “Technology of Soda Ash Production by the Ammonia-Soda Process” and “Engineering of Soda Ash”.
No, because the company has some sodium chloride on hand, and it also needs soda ash; therefore, it plans to set up a small-scale alkali production system

The ammonia-soda process cannot be miniaturized; for instance, the ammonia stripper relies on ample space to achieve high efficiency. In your case, it would be better to opt for small-scale diaphragm electrolysis to produce caustic soda and chlorine. The caustic soda can then be used to replace soda ash, or it can be reacted with carbon dioxide to produce soda ash. If interested, feel free to contact me via email at myben@126.com
If the scale is too small, it’s better to just buy it. The soda ash production process is lengthy, and environmental pressures are also increasing.
