Industrial enterprises take seriously the treatment of acidic gas emissions.
Wet scrubbing is common and effective way to capture acidic gases. In the scrubber, hydrofluoric acid is removed from the gas by reacting it with a caustic solution, for example, potassium hydroxide (KOH).
Vaisala K-PATENTS® Process refractometer is used for continuous in-line measurement of the KOH concentration in two locations:
The in-line measurement ensures safety operation, complete acid neutralization, and that no hydrofluoric acid (HF) acid enters the flare.
