Chemistry | NaOH | Inline sodium hydroxide concentration measurement on the example of naval closed loop scrubbers

An accurate control of the right sodium hydroxide concentration is an essential quality parameter for the efficiency of scrubbers. Anton Paar offers inline concentration measurement solutions by using the sound velocity sensor L-Sonic 5100 Version MON or the density sensor L-Dens 7400 Version INC.

NaOH Measurement

Sodium hydroxide solutions are applied in various industries and shades of dilution. Determining the concentration is an essential factor for the quality and effectiveness of different processes including the production of soaps, detergents, pulp, or in the alumina ore process.

Furthermore, sodium hydroxide plays an important role in the treatment of waste gas, where scrubbers are used to comply with the further enforced air pollution regulation. Aqueous NaOH solutions are used in the closed-loop scrubber to wash SOx contaminations out of the flue gas.

Anton Paar offers a wide range of measurement units to control the NaOH concentration during the dosage process, securing a safe operation of the scrubber. For continuous concentration measurements, Anton Paar’s L-Sonic 5100 Version MON and L-Dens 7400 Version INC provide a reliable solution.
