Stirring steam in the catalytic fractionation tower
Thread Content
Can the stirring steam at the bottom of the catalytic fractionation tower be turned off?
The stirring steam at the bottom of the catalytic fractionation tower is typically used to aid mixing and promote heat transfer; its shutdown can affect the processing efficiency of the materials within the tower as well as the quality of the product. It is recommended to assess the specific impact first before deciding whether to discontinue it. .
As long as the quality of the steam is guaranteed, it should be used as much as possible, and at the highest possible level, provided that this does not cause the slurry pump to run dry. Why? Because it is necessary to keep stirring continuously in order to prevent catalyst particles and dust from settling. Even with stirring steam in use, it is not possible to guarantee that no dust will settle; the key is to ensure that the steam has high quality – it must be free of water. By the way, the slurry pump should be switched over regularly, and the slurry steam generators (two or more; if there’s only one, then ignore this advice) also need to be switched over regularly and kept warm as backups.

Why stop? Could you tell me? OP, what are the considerations?
Stop means moving towards energy conservation and reduced consumption; it cannot be stopped as it is due to the stirring action
