IMPROVEMENTS IN APPARATUS FOR PERFORMING THE IMMISCIBLE REFRIGERANT FREEZE PROCESS FOR PURIFYING WATER

摘要

Plant for performing the immiscible refrigerant freeze process for purifying water has a crystallizer section with two sub-sections. The first sub-section forms a refrigerant injection zone in which ice crystal slurry is produced. The second sub section forms a disengagement zone in which entrained refrigerant is removed from the slurry and ice crystals are allowed to grow before transferring the slurry to the brine separating and washing section of the plant.
