Why isn’t sulfuric acid used in coal coking?
Thread Content
Our company is engaged in the trading of sulfuric acid in Xinjiang. There are many coking enterprises in Baicheng, in southern Xinjiang – why don’t they use sulfuric acid? Do they all use other processes to treat ammonia?
The ammonia washing process eliminates the need for sulfuric acid, while the ammonium sulfate process uses sulfuric acid
Some coking plants produce concentrated ammonia water, while others produce anhydrous ammonia; since they do not produce sulfuric acid, they don’t need concentrated sulfuric acid either.
Theoretically, phosphoric acid is available, but it is used less in practice. The sulfuric acid process is more mature; you can visit some coking plants to get a better understanding of it.
