Zusammenfassung:	Damp sodium bicarbonate filter cake is pre-dried and calcined to produce light soda as in a process comprising a carbon dioxide ebullated fluid bed pre-dryer working in connected series relationship with a plurality of carbon dioxide ebullated fluid bed/bag filter calcination systems such that bicarbonate decomposition during pre-drying is minimized and the thermal treatment of small particles during calcination is optimized.
