Regarding sodium sulfate
Thread Content
Gentlemen, let’s discuss whether a reaction between sodium sulfate and ammonium chloride can produce sulfuric acid
Our factory produces by-products such as sodium sulfate and ammonium chloride; their concentrations are low, so they cannot be sold. Discarding them contaminates the environment. If we could produce sulfuric acid AN, it would serve as a raw material for us. Dear sea friends, if it’s possible, resolving this major problem for our factory would be greatly appreciated.
The phase diagram data of this complex system should be studied, and then a method for crystallizing the product needs to be considered.
http://wenwen.soso.com/z/q174559717.htm, it seems a bit difficult. (NH4)2SO4 is insoluble in ethanol, propane, and ammonia. I’m not sure if the ammonia mentioned refers to ammonia water; if it is ammonia water, then it’s easier to deal with it. Do more experiments!
I don’t understand this area, so I’m learning from everyone!* ! ! !
It’s difficult; if it’s possible, it also requires a great deal of energy or other costs!
1# Wang Yibo: A direct reaction probably won’t work
Considering the solubilities of sodium chloride and sulfuric an at different temperatures should allow us to obtain sulfuric an; it’s just a matter of energy costs!
This manufacturing process is very difficult to implement; conventional methods certainly won’t work. Breaking the chemical bonds between sodium sulfate and ammonium chloride and forming new bonds to create sulfuric anhydride requires a large amount of energy, and such energy costs are definitely beyond what your company can afford. Additionally, conventional production equipment is not suitable for this process, and the investment required in such equipment would be enormous. For a product like sulfuric anhydride that does not have a high added value, the cost of producing it using this method will surely be higher than the market price. Moreover, as you mentioned, the purity of sodium sulfate and ammonium chloride in your company is not high, which means that the purification process will likely be even more complex, resulting in even higher costs.
This is a bit difficult, especially in this case – where is your factory located?
A direct reaction probably won’t work; if other conversion methods are available, it’s better to sell it instead. I’m thinking of treating ammonium chloride with carbonate first and then treating it with sodium sulfate – but if there’s anything wrong with this approach, that’s normal. Hehe,
