Dear acid enthusiasts, what do you think is an appropriate concentration of acid in the drying tower? Please share your opinions and discuss it together
If it’s too high, the acid mist level will be high; if it’s too low, the water content will be high
What range do you usually keep it within?
It is determined based on the process conditions: if water balance can be controlled, operation is carried out at the acid concentration for absorption; otherwise, it is controlled at 93±0.5%
At a concentration of 93%, the acid concentration meter tends to malfunction; therefore, the acid concentration is usually increased to around 95% in order to avoid the inflection point of the acid concentration-conductivity curve.
Great, this is exactly the situation we’re facing now. Teacher Danzhi, which brand of dry acid concentration analyzer provides more accurate results these days?
We usually keep it between 92.5–93.5%
