how to dry diesel with rock salt

[krecian]

can anyone help me in finding a manufacturer/package vendor who can design and supply diesel drying system using rock salts? diesel is having residual moisture, approx 500 ppm, (coming out from a co-alescer) to be dried to say 100 ppm.

You could dry it with sodium sulfate or solid causic if your volumes are small but you got me on the rock salt thing.

UOP, Des Plaines, Illinois could probably design it for you.

Google for "Dehydration with Dow Peladow". DOW offers a complete design and engineering package for designing your saltdryer yourself.

krecian,

Many licensors/EPCM companies can design salt driers. But some may not get involved with such a small poject. If that is the case, you would have to contact a salt vendor.

Newer designs seem to favour vacuum drying of diesel. It can dry down to about 50 ppm, and is better if you have the money, plot space and place to dispose of the off gas.

With salt drying you can use rock salt or CaCl salt. With rock salt you can only dry to a few degrees below the haze point. Thus, you may not be able to achieve 100 ppm. Salt drying also suffer from some operability issues, channeling, frequent draining, corrosion, effect of salt on downstream units, ect. It is still being used though.
