PVD Salt Production Via Brine Tank

This report contains a broad cost evaluation of PVD Salt via brine tank. Making a salt solution by flooding it with water is the first step in the procedure. The insoluble materials in the flooded brine are pumped out to a brine clarifier, where they settle to the bottom and are removed, leaving a clear brine solution that is then sent to a brine tank. In order to separate the magnesium and calcium salts present in addition to the salt in the brine tank, the necessary chemicals (like Sodium Hydroxide, Sodium Carbonate, Calcium Hydroxide) are added.

Following filtration, the brine is transferred to the last brine tank. From this tank, saturated brine is delivered to a continuous evaporation system, where it crystallises and is piped as slurry into a concentrate tank. After that, a hydro-cyclone battery is used to concentrate the salt slurry to a maximum of 50–60%.

This slurry is placed into a centrifuge, which produces salt cakes with 4-5% moisture. A smooth conveyor feeds the salt, which contains 4-5% moisture, to a fluid bed drier, where the iodisation is finished. The salt is fluidized by warm and ambient air in the Vibro fluid bed dryer before being dried and cooled. After that, a sieve machine receives the salt through a bucket elevator. The extra-large particles are gathered and transferred to the brine tank for ultimate re-dissolution.
