The premium grade rock salt by Naturelle is usually used in oil refneries and petrochemical industry. In oil refineries, when direct stripping steam from the stripper column is released, the hydro-desufurization units for jet and diesel reqire coalesce and salt dryer. The salt dryer completely avoids product off specification in water and appears hazy.
Size and size distribution of the rock salt particles is very important
Small particles cause severe corrosion in downstream system due to salt carry-over. On the other hand, large sized particles have significantly less effect on the surface area.
