Calcium Chloride |
| |
Calcium Chloride is a white crystalline salt. It is very soluble in water, extremely hygroscopic and liberates large amount of heat during water absorption and on dissociation it forms series of hydrates containing one, two, four and six moles of water per mole of Calcium chloride.
Raw Materials:
Lime stone- CaCO3
Hydrochloric acid |
| |
Manufacturing Process:
Calcium Chloride is obtained by direct neutralization of lime stone with hydrochloric acid
CaCO3 + 2HCl = CaCl2 + H2O + CO2
Consumption Norms |
| |
Calcium Chloride Manufacturing Process
Solvay process |
- Chemical Process of high purity limestone and salt brine to produce soda ash and Calcium Chloride
- CaCO3 + 2NaCl ---> Na2CO3 + CaCl2
- Produces a wide range of concentrations of both High Grade Liquid and Dry forms
|
| HCl Process |
- Reaction of HCl and Limestone (or other source of Calcium)
- Produces a wide range of concentrations of both High Grade Liquid and Dry forms
|
| Natural Brine |
- Often pumped out of underground naturally occurring sources
- Strength of liquid generally weaker and often inconsistent
- Contains impurities primarily in the form of other Chlorides
- Rarely find capability of producing Dry Forms
|
| Strengthened Brine |
- Natural Brine is processed generally with heat to increase concentration and consistency
|
| Brine Purification |
- Natural Brine is processed to remove impurities
|
Bi-Product
Calcium Chloride can be produced as a bi-product or waste of a chemical process |
| Major Other Uses: |
- In oil and gas well drilling
- As a coagulant in rubber Manufacturing
- As an accelerator in the ready mix concrete industry
- In de-icing during winter
- As drying agent, food additive and also in pharmaceuticals
