acid is produced in the United States primarily by four basic methods: the chlorination of organic chemicals; the combination of hydrogen and chlorine; the saltsulfuric acid production process; and, as a coproduct in the manufacture of silica. Most hydrochloric acid is produced from the chlorination of organic chemicals with much

· Silica sand, also known as quartz sand, is mainly composed of silica( SiO2), which is the main raw material for making sand has ordinary silica sand, refined silica sand and high purity silica sand. The content of silica in ordinary silica sand is between 90% and 99%, the content of iron oxide is less than %, the content of silica in refined silica sand is between 99% and ...
Sulfuric acid is normally used due to its affordable cost and its availability. However, improper use of sulfuric acid can cause irreversible fouling of the resin with calcium sulfate. To prevent this occurrence, the sulfuric acid is usually applied at a high flow rate (1 gpm per square foot of resin) and an initial concentration of 2% or less.

· However, if no Sulfuric Acid is available, you can just use Hydrochloric Acid. Finally, all that is left to do is to transform the Silicic Acid into Silicon Dioxide. Silicic Acid readily decomposes into amorphous Silicon Dioxide when mildly heated. So, to summarize: Quart(sand) –> Sodium Silie –> Silicic Acid –> Silicon Dioxide. Final ...
