Process for drying sodium carbonate peroxide

摘要

Manufacturing dry, free-flowing crystalline sodium carbonate peroxide by passing a gas stream at a temperature between 70 DEG and 150 DEG C into a drying zone containing moist sodium carbonate peroxide while maintaining the exit gas stream temperature between 50 DEG and 130 DEG 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 DEG and 40 DEG C, and removing a dry, free-flowing, crystalline sodium carbonate peroxide product containing between 0.001% and 0.20% by weight moisture.
