However, due to the calcium chloride is not easy to form a stable porous material, with the ammonia gas contact area is small, and the adsorption, desorption process is easy to swell, agglomerate, thus making it difficult to put into practical use in that regard. The process of absorption of chlorine in lime solution atomization impeller mechanical absorption indoors. After absorption of chlorine lime calcium chloride dihydrate, into the reactor, so that calcium hypochlorite decomposed into CaCl2 again. Part of the catalytic residues of calcium hypochlorite when the temperature is newly added 353K decomposition. CaCl2 containing lye output contains magnesium, SO4 2-, aluminum, iron and other impurities, and subject to purification treatment. To make lye plus BaCl2 SO4 2- generate BaSO4 precipitate removed. When the solubility of calcium chloride at pH10, lye is added to CaO, magnesium will occur Mg (OH) 2 precipitates calcium chloride, and aluminum hydroxide and iron hydroxide in pH3 or 4:00 began to precipitate. Purified treated lye filtered machine and after-containing CaCl2 400 ~ 450g / L of suspension solution. The suspension was fed to the atomization dryer, with hot air drying of about 573K, and dried, yielding the calcium chloride containing about 5% moisture. This method of chlorine up to 98% recyclable. The role of calcium chloride _ Haixu Chemical (certified) _ Taizhou calcium provided by Shouguang City Chemical Co. Haixu. Shouguang Haixu Chemical Co.
