Hello,

I am specifying a new salt tower for kerosene drying. We will use coarse sodium chloride as media, upflow operation. I am looking some existing designs that have a grating/screen and four layers of different sizes of gravel or ceramic balls to support the salt. What exactly the gravel/ceramic balls are for and how to determine what sizes are required?

Thanks!

Roberto

For Salt drier you need not to provide any support for salt.

Just dump the salt inside the vessel thats it.

I am handling this way our salt drier since 2006.

The support balls are there not so much to support the salt but to provide a method of distributing the inlet fluid (if you don't have a distributor pipe). It also takes up space that isn't salt and is reusable when you change the salt bed, reducing slightly the salt requirements (although I can't see that being a huge cost.


If you simply fill the vessel with salt and the liquid has to distribute through the salt initially, it will increase the risk of channelling, which will reduce the effective life of the salt bed.
