Sulfuric acid crystals
Thread Content
Our company uses 98% concentrated sulfuric acid for circulating water treatment and wastewater treatment; crystallization occurs when the temperature is low. What is the reason for this, and how can crystallization be prevented?
Switch to acid 93; acid 98 crystallizes at below 1.3 degrees
98 acid crystallizes at below 1.3 degrees
Consider using physical treatment methods for scale removal
When the temperature of concentrated sulfuric acid drops, it starts to crystallize; try using a solution with a lower concentration
Dilute the sulfuric acid; it needs to be diluted anyway in actual water treatment applications.
Experts say change it to 93%. Otherwise, if it’s cold in winter, your pipes will be under strain due to steam”
To prevent concentrated sulfuric acid from crystallizing, heat tracing pipes and insulation must be installed
