Abstract:
Manufacturing dry, free-flowing crystalline sodium carbonate peroxide by passing a gas stream at a temperature between 70. degree. and 150. degree. C into a drying zone containing moist sodium carbonate peroxide while maintaining the exit gas stream temperature between 50. degree. and 130. degree. C until the sodium carbonate contains between 0. 05% and 0. 5% by weight moisture, immediately passing the dried material into a cooling zone where the sodium carbonate peroxide temperature is lowered to between 0. degree. and 40. degree. C, and removing a dry, free-flowing, crystalline sodium carbonate peroxide product containing between 0. 001% and 0. 20% by weight moisture.
