Method for Enhancing Sodium Bicarbonate Flowability |
| 摘要 |
A process for producing crystalline sodium bicarbonate, comprising: feeding dried sodium bicarbonate solids with a mass flow rate to a fluid bed cooling unit, wherein said cooling unit comprises at least one cooling element through which flows a cooling fluid; flowing a fluidization gas stream in the fluid bed cooling unit to fluidize the dried sodium bicarbonate solids, in order for the dried sodium bicarbonate solids to be in thermal contact with the at least one cooling element; withdrawing a sodium bicarbonate product from the fluid bed cooling unit; and adjusting the temperature of the cooling fluid flowing through the at least one cooling element in order for the sodium bicarbonate product to have an outlet temperature of 95° F. or less, preferably less than 90° F., when being withdrawn from the fluid bed cooling unit. |

1. A process for producing crystalline sodium bicarbonate, comprising:
feeding dried sodium bicarbonate solids with a mass flow rate to a fluid bed cooling unit, wherein said cooling unit comprises at least one cooling element through which flows a cooling fluid,; flowing a fluidization gas stream in the fluid bed cooling unit to fluidize the dried sodium bicarbonate solids, in order for the dried sodium bicarbonate solids to be in thermal contact with the at least one cooling element; withdrawing a sodium bicarbonate product from the fluid bed cooling unit; and adjusting the temperature of the cooling fluid flowing through the at least one cooling element in order for the sodium bicarbonate product to have an outlet temperature of 95° F. or less when being withdrawn from the fluid bed cooling unit. |
