Advantages of Calcium Hypochlorite Plant

The advantage of LUVA Calcium Hypochlorite Plant technology is that through the recovery of salt and mother liquor, it uses an intermittent process to form uniform crystals, reduces energy consumption, and effectively reduces the amount of bleaching liquid, thereby reducing the price of chlorine conversion and the consumption of raw materials.

Salt recovery

32% NaOH and mother liquor are pumped into a reaction kettle according to a certain proportion, chlorine gas is introduced for reaction, and the temperature in the reaction kettle is controlled by cooling water at 12°C, so that the reaction kettle is in the form of NaCl crystals, and finally the NaCl crystals are separated by centrifugal separation. It can be mixed and dissolved with industrial salt in caustic soda plant and used in caustic soda plant.

Using intermittent process. During crystallization, the crystal particle size is more uniform than the continuous process, which is conducive to centrifugal separation and drying, also the energy consumption is low.

Mother liquor recovery

the Ca(ClO)2 and NaCl crystals are in equilibrium, and the concentration in the mother liquor is basically at a stable range. The NaCl concentration is ~20% and the Ca(ClO)2 concentration is 6~10%. The amount of bleaching liquid is about 4.8 tons/ton product, and it is difficult to handle such a large amount if directly sold. The effective chlorine conversion price is also relatively low and consumes a lot of raw materials. Using mother liquor reusing technology, the bleaching liquid will be reduced from 4.8 tons/ton product to 2.5 tons/ton product.
