Controlling Alumina/Caustic Ratio - Emerson

Electrical conductivity is used to control the addition of caustic to the digester to optimize the yield of dis-solved alumina in the process. The amount of caustic added in this step is proportional to the concentration of alumina in the stream. Controlling this alumina/ caustic (A/C) ratio in the digester is essential to the process.
