In aviation, ethylene glycol (EG) or propylene glycol (PG) are used as de-icing and anti-icing fluids that keep the atmospheric ice from accumulating on an aircraft’s surfaces during the flight.
After the de-icing on the ground, the used liquid is captured into the containment system to prevent the streams contamination.
Vaisala K-PATENTS® process refractometer is for monitoring:
The in-line process refractometer is also used for measuring the final concentration after the dehydration process before the glycol is returned to storage.
