Anhydrous calcium chloride prills, chemical formula CaCl₂, is white thornshaped spherical granular product. Main industrial purity ≥94%, particle size 13mm / 35mm. Featured by strong hygroscopicity, exothermic dissolution, excellent freeflow property and lowdust performance. Compared with flake or powder calcium chloride, prills have less breakage during transportation and feeding, good permeability, widely used in multiple heavyindustry sectors.

1. Industrial Desiccant & Dehydrating Agent
Anhydrous CaCl₂ prills is a classic neutral inorganic desiccant. It can absorb moisture up to 300% of its own weight.
Gas drying: Fill drying towers and drying pipes for drying N₂, O₂, H₂, HCl, SO₂ and other neutral & acidic industrial gases. Not applicable for ammoniacontaining gas.
Organic liquid dehydration: Dehydrating agent for manufacturing alcohol, ester, ether and acrylic resin, removing trace water in organic solvents.
Container & warehouse moistureproof: Used for seafreight container dehumidification, warehouse storage dehumidification, preventing cargo dampdamage and metal rusting.
Prillshape advantage: Hard granular structure, low dust, not easy to pulverize, keep stable permeability when filled into towers, avoid channeling phenomenon.
2. Oil & Gas Drilling Industry
One of the core bulkconsumption scenarios for anhydrous calcium chloride prills.
Prepare highdensity calcium chloride brine, used for drilling fluid, completion fluid and workover fluid. Increase brine density, balance underground formation pressure, stabilize shale stratum, restrain clay swelling, prevent well wall collapse and leakage risk.
Reduce formation damage to oilgas reservoirs, suitable for onshore & offshore well operations.
Used as dehydrating agent for petrochemical processing.
3. Construction Industry: Concrete Accelerator & Antifreeze Agent
Dissolved calcium chloride solution can accelerate cement hydration reaction.
Earlystrength accelerator: Shorten concrete curing cycle, improve earlystage strength.
Winterconstruction antifreeze: Lower freezing point of water inside concrete, prevent mortar & concrete from frost crack under lowtemperature environment, enable winter pouring construction.
Note: Not recommended for steelreinforced concrete with strict anticorrosion requirement, chloride ion may cause steel bar corrosion.
4. Road Deicing, Antifreeze & Dust Suppression
Deicing & antifreeze: Dissolution releases large heat, greatly lower water freezing point. Work efficiently under20℃~30℃, applied for highway, port, parking lot, airport pavement snowmelting and antiicing. Prills spread evenly with low dust, convenient for mechanical spreading.
Dust control for mine & unpaved road: Absorb ambient moisture, keep road surface damp, bond dust particles. Widely used for mine yard, coal storage yard, gravel road, port dustsuppression & fogelimination. Reduce dust flying and improve site safety condition.
5. Refrigeration & Brine Refrigerant
Anhydrous calcium chloride dissolves in water to form stable calcium chloride brine, widely used as circulating refrigerant for refrigerators, coldstorage houses, icemaking workshops and lowtemperature chemical reaction units. Advantages: stable thermal conductivity, low cost, suitable for mediumlow temperature refrigeration systems.

6. WasteWater Treatment Industry
Supply calcium ion source, precipitate fluoride ion, phosphate ion in industrial wastewater.
Adjust waterbody ion strength, assist flocculationsedimentation process for printingdyeing, metallurgical wastewater.
Used for circulating water treatment of industrial equipment.
7. Metallurgy & Rubber & Other Industrial Applications
Metallurgy: Protective agent and refining agent for magnesiumaluminum smelting, remove impurity in molten alloy, improve finishedproduct quality. Rubber industry: Latex coagulant for rubber production. Papermaking & recycling paper: Deinking agent for wastepaper processing. Textile industry: Textile fireretardant agent.
