What are the differences in the quality of acid produced from smelting flue gas, pyrite, and sulfur?
This section contains relevant posts: How can concentrated sulfuric acid produced by sulfur-based acid production, pyrite-based acid production, and acid production from smelting flue gas be distinguished from one another? http://bbs.hcbbs.com/redirect.php?tid=247282&goto=lastpost
In the production of sulfuric acid from sulfur, sulfur is burned directly to produce sulfur dioxide fumes; as a result, there are almost no impurities in these initial fumes – no dust, arsenic, fluorine, or other impurities. Therefore, no purification process is required, and there is also no generation of acid mist. Water is present, though, in the form of moisture in the air. In contrast, when producing sulfuric acid from smelting fumes or pyrite, many impurities are present in the initial fumes after smelting and in the boiling furnaces, so a purification process is necessary to ensure that the required standards are met.
Acids made from sulfur can reach top quality
Smelting to produce acid. Acid production from pyrite can also achieve top-quality results
What was mentioned earlier are just the raw materials and production processes; the end products are all of the same type. As long as sulfuric acid is produced in accordance with certain product standards, there is no significant difference in quality. In fact, the most noticeable difference among sulfuric acid products is that the concentration of each batch can vary. As for what purity level to produce, this can be determined during the subsequent purification and impurity removal processes, and it has little to do with the raw materials or the main production process.
