Mainly include 1. Refrigerator, 2. Moving crystallizer, 3. Nitrate precipitation tank, 4. Centrifuge
To be precise, it’s not a crystallizer; rather, it should be a cooler. The formation and growth of crystals take place in the nitrate precipitation tank.
Freeze-denitration equipment (Kai Membrane process): Pre-cooler, halide replacement tank, freeze circulation pump, evaporator + refrigeration unit, nitrate precipitation tank, nitrate slurry feed pump, cyclone separator, centrifuge, dilute nitrate brine tank, dilute nitrate brine pump
Brine cooler, Analytical cooler, Pipe filter, Static mixer, Sodium sulfite buffer tank, Hydrochloric acid buffer tank, Brine intermediate tank, Safety filter, Cleaning solution filter, Raw brine storage tank, Nitrate-rich brine intermediate tank, Recycled brine tank, Cleaning solution tank, Pre-cooler, Evaporator, Brine mixing tank, Nitrite precipitation tank, Nitrate-poor brine tank, Cyclone separator, Membrane module, Sodium sulfite metering pump, Hydrochloric acid pump, Brine transfer pump, Hydrochloric acid metering pump, Raw brine transfer pump, Nitrate-rich brine transfer pump, Recycled brine transfer pump, Cleaning pump, Flushing pump, Nitrate-poor brine pump, Nitric slurry feed pump
How should the evaporator load for denitrification be calculated? ? Is there any information on this topic? ? Thank you
What is the typical water temperature of the mixed halide stream entering and leaving the evaporator? ? What is the required control accuracy? ? What is the typical water temperature for nitration? How often should it be flushed? ? Thank you
