PROCESS AND PLANT FOR MANUFACTURING MONOHYDRATED SODIUM CARBONATE

摘要

1. Process for manufacturing sodium carbonate monohydrate, according to which anhydrous sodium carbonate and water are mixed with an aqueous suspension of sodium carbonate monohydrate crystals at a temperature below the transition point of sodium carbonate monohydrate to anhydrous sodium carbonate, the resulting mixture is homogenised and the crystals of sodium carbonate monohydrate are separated, characterised in that, to mix the anhydrous sodium carbonate with the suspension, the anhydrous sodium carbonate is introduced in a suspension zone in which a vortex is created.
