Calcium Chloride Production Line

Product description: Calcium Chloride Plant | Calcium Chloride Production LineCalcium chloride is a white or off-white porous block, granular and powdery product. It is odorless, slightly bitter, highly hygroscopic and extremely deliquescent when exposed to air. It is easily soluble in water while releasing a lot of heat. Calcium chloride has a wide range of uses and is mostly used as a desiccant and dehydrating agent. Its aqueous solution is the main refrigerant for ammonia refrigerators. It can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze. It is used as antifogging agent and deicing agent in ports and airports, road dust collector and fabric fireproofing agent.The production methods of calcium chloride is hydrochloric acid and limestone method. The products are of good quality and widely used. At present, most of them are produced by by-product hydrochloric acid, mainly anhydrous calcium chloride.Process introductionReaction section: The hydrochloric acid sent from the tank area is added to the reaction tank containing limestone through the hydrochloric acid high-level tank. The hydrochloric acid reacts with the limestone in the tank to generate calcium chloride mother liquor, and the acidic calcium chloride solution generated by the reaction is put into the neutralization tank by self-flow. Add calcium hydroxide to the neutralization tank to neutralize excess acid. The neutralized calcium chloride solution is pumped to the filter press for continuous filtration, and the filtered clear liquid is put into the mother liquor receiving tank by self-flow. The mother liquor in the mother liquor receiving tank is pumped to the large storage tank of calcium chloride mother liquor for static storage. During the reaction, carbon dioxide will be released, and part of the tail gas such as hydrogen chloride will be entrained.

Calcium Chloride Plant | Calcium Chloride Production Line

Calcium chloride is a white or off-white porous block, granular and powdery product. It is odorless, slightly bitter, highly hygroscopic and extremely deliquescent when exposed to air. It is easily soluble in water while releasing a lot of heat. Calcium chloride has a wide range of uses and is mostly used as a desiccant and dehydrating agent. Its aqueous solution is the main refrigerant for ammonia refrigerators. It can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze. It is used as antifogging agent and deicing agent in ports and airports, road dust collector and fabric fireproofing agent.

The production methods of calcium chloride is hydrochloric acid and limestone method. The products are of good quality and widely used. At present, most of them are produced by by-product hydrochloric acid, mainly anhydrous calcium chloride.


Process introduction

Reaction section: The hydrochloric acid sent from the tank area is added to the reaction tank containing limestone through the hydrochloric acid high-level tank. The hydrochloric acid reacts with the limestone in the tank to generate calcium chloride mother liquor, and the acidic calcium chloride solution generated by the reaction is put into the neutralization tank by self-flow. Add calcium hydroxide to the neutralization tank to neutralize excess acid. The neutralized calcium chloride solution is pumped to the filter press for continuous filtration, and the filtered clear liquid is put into the mother liquor receiving tank by self-flow. The mother liquor in the mother liquor receiving tank is pumped to the large storage tank of calcium chloride mother liquor for static storage. During the reaction, carbon dioxide will be released, and part of the tail gas such as hydrogen chloride will be entrained. The acid waste gas generated by the reaction tank and the hydrochloric acid high-level tank is all collected and absorbed by the two stage tail gas absorption towers, and discharged after reaching the standard.

Chemical equation: 2HCl+CaCO3CaCl2+H2O+ CO2

Granulation section: the static calcium chloride mother liquor is sent to the circulation tank, and then pumped into the foam absorption tower to wash the high temperature tail gas from the granulation tower, and the calcium chloride dust and heat in the tail gas are recovered to  concentrate calcium chloride mother liquor. The concentrated calcium chloride mother liquor is pumped into the atomizing nozzle on the granulation tower, under the action of high temperature hot air, it is dried to form granular anhydrous calcium chloride, which is then cooled and screened for packaging. The high-temperature tail gas generated during the drying and granulation process is passed into the foam tower, and the circulating calcium chloride mother liquor absorbs part of the heat and calcium chloride dust, and then the tail gas is pumped into the tail gas cylinder by the tail gas fan for air emission.

  • Sodium Silicate Plant | Sodium Silicate FurnaceThe main raw materials of dry process sodium silicate production are soda ash and quartz sand. The process is batching, firing and melting.Process description1. Batching: batching can be divided into manual batching and automatic batching. Manual batching is manually weighing the quartz sand and soda ash according to the proportion of the formula, then put into the furnace to react through lifter. Automatic batching is automatically weighing the quartz sand and soda ash, then automatically put into the furnace to react through loader.2. Firing: after the materials are fed into the furnace, the chemical reaction is occurred at the high temperature of 1350-1450℃. The molten sodium silicate form glassy solid lumps by air cooling or water cooling. Finished products are sent to warehouses or stacked or cooled to normal temperature. The regenerative preheater is used in the design of the reflector. The air and coal gas can be separately preheated to 1100℃ and 900℃ by 1200℃ of flue gas from furnace, temperature of exhaust gas is reduced to below 180℃, so as to save energy and reduce consumption.3. Melting: if liquid sodium silicate is needed, the solid sodium silicate can be melted into liquid. There are two ways to melt, the water-cooled solid is melted by the rotary melting tank, and the air-cooled solid is melted by static melting tank.
