On-line analysis of CaO in Sodium
Carbonate plant
Continuous information on the accurate concentration of active CaO in the column is of vital importance to the economic operation of a Sodium Carbonate plant
The continuous information on the accurate concentration of active CaO in the column is of vital importance to the economic operation of the plant Hence the requirement of the operators to have this information available frequently and quickly as the results will enable the technicians to stay in close contact with the process and run it at its optimum

Attempts have been made to have this analysis done by pH measurement, but insufficient accuracy, as well as lack of validity of the pH probe to do a direct measurement made the analysis not suitable for optimal production.
Similarly even non-specific density monitoring has been attempted, without success.
The only method having the right degree of accuracy is still titration, but the route via the lab is too time consuming.
The best possible option next is to have a device which could run the analysis on-line, while utilising the titration method.
This is a realistic option with the Applikon Process Analyser ADI 2040, which offers a variety of superb titration methods.
Titration is one of the absolute methods, meaning it does not require cumbersome validation procedures, due to the steep change in pH at the EP, only the relative value is significant and used to calculate the ml quantity of titrant consumed.
The 2040 has the ability to run multiple titrations on multiple sample streams, simultaneously, and cuts reagent usage down to just 25% of what was previously associated with process titrators .
With its corrosion resistant polystyrene wet part and its even more rugged components this analyser will last numerous years, and provide a cornerstone contribution to the plant performance. Request a free brochure from Applikon Analytical ...
