Chemistry | Chlor-alkali | Optimization of the chlor-alkali process by online concentration measurements
An accurate control of the required hydrochloric acid and caustic soda concentrations through the whole chlor-alkali process is important and can easily be accomplished with Anton Paar's density sensor L-Dens 7400 and sound velocity sensor L-Sonic 5100.
The chlor-alkali process is an important method to produce many basic chemicals like, hydrochloric acid, caustic soda, chloride and hydrogen.
There are 3 existing chlor-alkali processes which are distinguished in the different kinds of anode-cathode materials and their type of membrane whereby the membrane cell process is the most common one.
