When producing compound fertilizers using the amino acid method, what are the appropriate amounts of ammonia and sulfuric acid? Some people say to use 30 KG of ammonia and 30 KG of acid each, but I calculated that the losses would be quite high.
It should be 20 ammonia and 30 acid; part of the ammonia is absorbed by monoammonium phosphate and converted into diammonium phosphate. There is definitely some loss, but not much
Thank you. Is your main processing method the amino acid method?
Half is by the amino acid method, and half by conventional steam drum granulation. The amino acid method is rather complicated; although the yield per unit is high, the key factor is the price of sulfuric acid. The amino acid process and steam drum granulation can be carried out on the same production line; it’s better to choose the process with lower costs for production
What are the things to note regarding the start-up and shutdown of the amino acid process? If continuous driving is not possible, can the amino acid method be used?
