Concentration processes Lime Soda.Process. Lime (CaO) reacts with a dilute (10—14%), hot (100°C) soda ash solution in a series of agitated tanks producing caustic and calcium carbonate.Although dilute alkaH solutions increase the conversion, the reaction does not go to completion and, in practice, only about 90% of the stoichiometric amount of lime is added.

How Is Lemon Juice Concentrate Made? A Brief Overview of the Process
The concentration process typically involves two main methods: evaporation and freezing. Evaporation Method. In the evaporation method, the juice is heated in large stainless-steel tanks. The heat causes the water in the juice to evaporate, leaving behind a more concentrated lemon juice. The evaporated water is collected and removed from the ...
