In a process producing KCIO3 salt, 1000 kg/hr of a feed solution containing 20% by wt. KCIO3 (and traces of impurities) is feed to the evaporator which evaporates some water at 422K to produce 50% by wt. KCIO3 solution. This solution is then feed to a crystallizer at 32°C where crystals containing 96% by wt. KCIO3 are removed. The saturated solution from the crystallizer is recycled by the evaporator. Calculate the (a) amount of crystals produced and (b) amount of solution recycled. Solubility @ 32° C= 12 kg KCIO3 / 100 kg H2O
