The plant provides for the drying and cooling of NaCl generated in the crystalization reactors and dewatered
in pusher centrifuges.
The wet NaCl is fed directly to the product receiving zone of the fluid bed dryer/cooler. The dryer works with
pure convective drying and cooling.
The drying and the cooling stage has its own filtration and compressing equipment included in the intake air
installation with individual air heating for the drying air.
After leaving the fluid bed dryer the exhaust air is cleaned by cyclone and wet scrubber dedusting system
before it is conveyed to the ambient.
