Problems regarding the hydration process for producing heavy soda ash
Thread Content
Why is only the ammonia-soda process followed by hydration used to produce heavy soda ash? Is it not possible to hydrate the product after the ammonia-soda process to produce dense soda ash? Could you provide a detailed introduction?
No investigation, no right to speak. Who says that the ammonia-soda process can’t be used to produce hydrated heavy soda ash? Hubei Shuanghuan built a plant for producing hydrated heavy soda ash many years ago—around the year 2000, I believe. Currently, the stable output is also 20,000 tons per year. Maybe they even expanded production after I left. It’s just that the salt content is a bit inconsistent, but it still meets the **standards.

I just wanted to ask whether it’s possible to carry out hydration to produce heavy soda ash after the combined alkali process. I also consulted someone on this matter, and it is indeed feasible. However, the quality of heavy soda ash produced via hydration after the combined alkali process is much inferior compared to that produced using the ammonia-soda process
They can all be used to produce hydrated crystals. Tianjin Soda Plant has a patented technology for producing heavy-duty soda ash via liquid-phase hydration. The salt content and particle size of the product are both satisfactory. If you’re interested, feel free to look into it
In the ammonia-soda process, light ash is used together with water to produce heavy ash. The quality of this product is virtually no different from that produced via the ammonia-soda process. Our company has been using this method for over a year now; the key issue is finding a suitable disposal site for the displaced mother liquor
More than a decade ago, I worked on hydration; I designed my own hydration machine. Trade name for dense soda ash: High-quality dense soda ash.
Sodium bicarbonate can be produced by both the extrusion method and the hydration crystallization method.
The ammonia-soda process can produce heavy soda ash. Our company uses the solid-phase hydration method to produce heavy soda ash. Send the light ash to the hydrating machine; after adding water, send it to the heavy ash calcination furnace. Generate heavy alkali. Its steam uses low-pressure steam at 1.6 MPa. In production, the key is to control the water-to-lime ratio in the hydrator. That is, controlling the amount of water added to the hydrator.
